Provides a unified API for counting tokens across 6+ LLM providers (OpenAI, Anthropic, Gemini, Mistral, Groq, DeepSeek) by wrapping each provider's native tokenization logic or implementing compatible algorithms. Uses provider-specific token encoders (e.g., tiktoken for OpenAI, claude-tokenizer for Anthropic) behind a normalized interface, allowing developers to swap providers without changing token-counting code. Handles model-specific tokenization differences (e.g., different BPE vocabularies, special token handling) transparently.
Unique: Zero-dependency design that bundles provider-specific tokenizers locally rather than making API calls or requiring external services, enabling offline token counting with no network latency or rate limits
vs alternatives: Faster and more cost-effective than calling each provider's API for token counts, and more accurate than generic BPE approximations because it uses provider-native encoders
Automatically calculates monetary cost for each LLM API request by multiplying token counts (input + output) by provider-specific pricing rates. Maintains an internal pricing table for each provider and model, updated to reflect current pricing. Supports both streaming and non-streaming requests, calculating costs incrementally as tokens arrive. Returns cost breakdowns (prompt cost, completion cost, total) alongside token counts, enabling per-request cost visibility without manual billing API queries.
Unique: Calculates costs at request granularity (not just at billing cycle end) by embedding pricing logic directly in the request path, enabling real-time cost visibility and per-request decision-making without external billing API calls
vs alternatives: Provides immediate cost feedback per request (vs. waiting for monthly bills), and integrates cost calculation into application logic (vs. external billing dashboards that lack real-time granularity)
Tracks token usage and cost for streaming LLM responses by intercepting and counting tokens as they arrive in chunks, rather than waiting for the complete response. Maintains running totals of prompt tokens, completion tokens, and cost as the stream progresses. Works by wrapping streaming response handlers or middleware to parse token counts from provider-specific stream metadata (e.g., OpenAI's usage field in stream deltas). Enables cost visibility before streaming completes, supporting early termination or cost-aware stream handling.
Unique: Intercepts streaming responses at the middleware level to extract and aggregate token counts from provider-specific stream deltas, enabling cost visibility before stream completion without buffering the entire response
vs alternatives: Provides real-time cost feedback during streaming (vs. batch cost calculation after completion), and supports cost-aware stream termination (vs. passive cost tracking)
Integrates with LLM client libraries (OpenAI SDK, Anthropic SDK, etc.) via middleware or wrapper patterns to automatically inject cost tracking into every API call without modifying application code. Intercepts requests before they're sent and responses after they're received, extracting token counts and calculating costs transparently. Supports both callback-based and promise-based middleware patterns, and works with async/await code. Accumulates costs across multiple requests, enabling application-level cost aggregation and reporting.
Unique: Implements transparent middleware integration that hooks into provider SDKs at the request/response level, enabling automatic cost tracking without modifying application code or requiring explicit cost calculation calls
vs alternatives: Reduces boilerplate compared to manual cost tracking in every LLM call, and provides automatic aggregation vs. requiring developers to manually sum costs
Aggregates costs across multiple requests and provides structured reports broken down by time period, model, provider, or custom categories. Maintains running totals and supports queries like 'total cost in last hour', 'cost by model', 'cost by provider'. Implements in-memory cost accumulation with optional export to JSON or CSV for external analysis. Supports custom tagging of requests (e.g., by user, feature, or endpoint) to enable cost attribution and chargeback scenarios.
Unique: Provides in-memory cost aggregation with flexible grouping (by model, provider, time, or custom tags) and export capabilities, enabling cost attribution and analysis without requiring external analytics infrastructure
vs alternatives: Simpler than integrating external analytics platforms, and supports custom tagging for cost attribution (vs. provider dashboards that only show aggregate costs)
Manages a versioned pricing table for all supported models across all providers, allowing developers to update rates as providers change pricing. Supports both built-in default pricing (updated with library releases) and custom pricing overrides for specific models or providers. Implements a configuration API to set custom rates programmatically, and supports loading pricing from external sources (JSON files, environment variables, or APIs). Tracks pricing version to enable cost recalculation with historical rates if needed.
Unique: Provides a configuration API for custom pricing overrides with version tracking, enabling organizations to use negotiated rates and maintain audit trails without modifying library code
vs alternatives: More flexible than hardcoded pricing (supports custom rates), and simpler than building a separate pricing service (built-in configuration management)
Implements budget tracking and enforcement by monitoring cumulative costs against user-defined spending limits. Supports per-request budget checks (reject requests that would exceed budget), per-session limits, and per-time-period limits (e.g., daily, monthly). Provides callback hooks or event emitters to trigger alerts when costs approach or exceed thresholds. Integrates with cost tracking to enable real-time budget enforcement without external services.
Unique: Implements in-process budget enforcement with real-time alerts, enabling cost control without external services or API calls, and supporting request-level budget checks for immediate cost prevention
vs alternatives: Faster and more responsive than external budget services (no API latency), and enables request-level enforcement (vs. post-hoc billing alerts)
Analyzes historical cost and token usage data to recommend the most cost-efficient models for specific use cases. Calculates efficiency metrics (cost per token, cost per request, tokens per dollar) for each model and provides rankings. Supports filtering by quality constraints (e.g., 'recommend models with >90% quality score') or latency constraints. Enables A/B testing by comparing costs across models for the same prompts or use cases.
Unique: Analyzes historical cost data to generate model recommendations with efficiency rankings, enabling data-driven model selection without external analytics platforms
vs alternatives: Provides automated recommendations based on actual usage patterns (vs. manual comparison), and integrates with cost tracking for seamless analysis
Crawls 11+ heterogeneous platforms (Zhihu, Weibo, Bilibili, Twitter, Reddit, HackerNews, etc.) and RSS feeds using platform-specific scrapers, normalizes disparate data schemas into a unified NewsItem model, and deduplicates content across sources using fuzzy title matching and URL canonicalization. The system maintains platform-specific metadata (rank, heat value, engagement metrics) while presenting a single normalized feed, enabling cross-platform trend detection that would be invisible within individual platform silos.
Unique: Implements platform-specific crawler modules with unified NewsItem schema and fuzzy deduplication across 11+ heterogeneous sources (Chinese + international), rather than relying on single-platform APIs or generic RSS parsing. Maintains platform-specific metadata (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) for weighted hotspot scoring.
vs alternatives: Covers more platforms (especially Chinese social media) with deeper metadata extraction than generic RSS aggregators, and provides unified deduplication across sources unlike single-platform monitoring tools.
Implements a multi-stage filtering pipeline that matches news items against user-defined keywords using regex patterns, required word lists, and excluded word lists. The system applies frequency-based scoring (keyword occurrence count) combined with platform hotspot weights to rank filtered results. Configuration is stored in frequency_words.txt with support for regex patterns, AND/OR/NOT boolean operators, and per-keyword weighting. Filtering occurs at collection time (reducing storage) and again at report generation time (enabling dynamic reconfiguration without re-crawling).
Unique: Combines regex pattern matching with frequency-based scoring and platform hotspot weighting (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) in a two-stage pipeline (collection-time and report-time filtering). Supports dynamic reconfiguration without re-crawling by applying filters at report generation.
TrendRadar scores higher at 58/100 vs ai-cost-meter at 39/100.

Search the match graph →© 2026 Unfragile. Stronger through disorder.
vs alternatives: More flexible than simple keyword matching (supports regex and boolean logic) and more efficient than semantic filtering (no LLM overhead), making it suitable for real-time filtering at scale.
Detects newly emerged topics by comparing current crawl results against historical data stored in the system. Topics are marked as 🆕 (new) if they appear for the first time in the current crawl or if their hotspot rank increased significantly compared to previous crawls. The system tracks topic emergence velocity (how quickly a topic rises in rankings) and flags topics with unusual acceleration. New topic detection is performed at report generation time, enabling dynamic detection without re-crawling. The system maintains a historical hotspot index for comparison.
Unique: Detects new topics by comparing current hotspot rankings against historical data, marking topics with significant rank increases as 🆕. Tracks emergence velocity to distinguish breaking news from sustained trends.
vs alternatives: More efficient than semantic similarity detection (no LLM overhead) and more accurate than simple first-appearance detection (accounts for re-emerging topics), but requires historical baseline data.
Provides a web-based UI for editing TrendRadar configuration files (config.yaml, frequency_words.txt, timeline.yaml) with real-time validation and preview. The editor supports: (1) syntax highlighting for YAML and regex, (2) validation of keyword patterns (regex compilation check), (3) preview of filtered results based on current keyword configuration, (4) drag-and-drop channel configuration, (5) schedule preview (shows next 10 execution times). Changes are validated before saving, preventing configuration errors. The editor is optional; users can edit config files directly.
Unique: Provides web-based configuration editor with real-time validation, regex preview, and schedule visualization. Enables non-technical users to configure TrendRadar without editing YAML files.
vs alternatives: More user-friendly than manual YAML editing and provides validation feedback, but adds operational complexity compared to file-based configuration.
Integrates LiteLLM to provide vendor-agnostic AI analysis and summarization of filtered news items. Users configure their preferred LLM provider (OpenAI, Anthropic, Ollama, local models, etc.) once in config.yaml, and the system automatically routes analysis requests to that provider. The AI analysis capability includes: (1) automated summarization of long articles into key points, (2) sentiment analysis (positive/negative/neutral), (3) trend prediction based on historical patterns, and (4) custom analysis prompts. Analysis results are cached to avoid redundant API calls and can be pushed directly to notification channels.
Unique: Uses LiteLLM abstraction layer to support any LLM provider (OpenAI, Anthropic, Ollama, local models) with single configuration, enabling provider switching without code changes. Caches analysis results to reduce redundant API calls and costs.
vs alternatives: More flexible than hardcoded OpenAI integration (supports any LiteLLM provider) and cheaper than dedicated sentiment analysis APIs (can use local models), but slower than rule-based sentiment analysis.
Leverages LiteLLM to translate news content from source languages (primarily Chinese) to target languages (English, etc.) on-demand. The system detects source language automatically (via langdetect or similar), caches translations to avoid re-translating identical content, and batches translation requests to reduce API calls. Translations are stored alongside original content, enabling bilingual reports and multi-language notification delivery. Translation can be triggered at collection time (all news) or report time (only filtered news).
Unique: Implements provider-agnostic translation via LiteLLM with automatic language detection, content-based caching, and batch request optimization. Stores translations alongside originals for bilingual report generation.
vs alternatives: More flexible than dedicated translation APIs (supports any LiteLLM provider) and cheaper than commercial translation services when using local models, but slower than specialized translation APIs.
Implements a notification abstraction layer supporting 9+ delivery channels (WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc.). Each channel has a provider-specific formatter that converts normalized news items into channel-appropriate messages (e.g., WeChat card format, Telegram markdown, email HTML). The system batches notifications atomically—all news items for a report are sent as a single batch to each channel, ensuring consistency and reducing API calls. Message formatting respects channel constraints (character limits, attachment limits, etc.) and supports templating for customization.
Unique: Implements atomic message batching across 9+ heterogeneous channels with provider-specific formatters and constraint-aware truncation. Single configuration enables simultaneous delivery to WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc. without code changes.
vs alternatives: Supports more channels (especially Chinese platforms like WeWork, Feishu) than generic notification services, and batching reduces API calls and spam compared to per-item notifications.
Exposes TrendRadar's data and analysis capabilities as an MCP server, enabling AI agents and LLM applications to query trends, perform analysis, and generate insights through natural language. The MCP server implements tools for: (1) querying filtered news by keyword/date/platform, (2) retrieving trend statistics and hotspot rankings, (3) running custom analysis on news subsets, (4) generating reports in various formats. Clients (Claude, other LLM agents) can invoke these tools via MCP protocol, enabling conversational exploration of trends without direct database access. The server maintains state across multiple requests, allowing multi-turn conversations about trends.
Unique: Implements full MCP server exposing trend data and analysis tools to LLM agents, enabling conversational queries and multi-turn analysis workflows. Maintains state across requests and supports complex tool invocations (filtering, analysis, report generation).
vs alternatives: Enables conversational access to trends (vs. API-only access) and integrates with LLM agent workflows (vs. standalone tools), but adds operational complexity compared to simple REST APIs.
