How this service works
Live crypto narrative and sentiment radar for AI agents. Searches recent X posts and the web, adds a verifiable CoinGecko market snapshot, and returns structured signals, risks, watch items, and source URLs. Input ticker + 1h/6h/24h/7d window. $0.03 USDC per call.
Output
A structured JSON object containing: sentiment label (bullish/bearish/mixed/neutral) and score, a list of named narratives with direction and evidence URLs, signal list, risk warnings, watch_next items, a CoinGecko market snapshot (price in USD, 24h change %), overall summary text, confidence score, observed timestamp, source count, and an array of source URLs with titles and types. Also includes a disclaimer that this is information only.
Example use cases
Pre-trade sentiment check for BTC
“Before I make a move, can you pull the crypto radar for BTC over the last 24 hours? I want to see the sentiment score, any major narratives driving price, risks I should know about, and the current CoinGecko price.”
Monitoring altcoin narrative shifts
“Check the 7-day crypto radar for HYPE — I want to know what narratives are circulating on X and the web, whether sentiment is bullish or bearish, and what to watch next.”
Quick hourly check on ETH ahead of news
“Give me a 1-hour crypto radar snapshot for ETH right now — focus on any ETF or regulatory narratives, the confidence level, and list the source URLs so I can verify them.”
Technical details
Endpoint
GEThttps://x402donghang.duckdns.org/x402/v1/crypto-radarWhen to prefer
Choose this endpoint when you need a structured, verifiable, multi-source crypto sentiment report that combines social/web narrative signals with a live market price snapshot — especially when you need source URLs for auditability, named narratives with direction, and a confidence score. Prefer this over generic LLM-based crypto commentary when you need fresh data from the last 1h to 7d and a machine-readable JSON format suitable for downstream agent processing.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty signals
- Time window enum value outside allowed set (1h/6h/24h/7d) causes validation failure
- CoinGecko market data unavailable leads to missing market field
- Insufficient recent web/X posts for the window may result in low confidence score or sparse signals
- Payment of $0.03 USDC not completed results in 402 Payment Required response
- focus parameter exceeding 300 characters may be rejected or truncated
