How this service works
Pay-per-call BTC/ETH briefs via x402
Output
A JSON object containing BTC's current price, 14-day RSI, 20-day and 50-day simple moving averages, a trend score and signal label (e.g. 'neutral'), RSI state, sentiment classification, fear & greed index value, 24-hour and 7-day percentage price changes, and an informational disclaimer.
Example use cases
Morning crypto portfolio check
“What's Bitcoin looking like right now? Give me the price, trend signal, and whether RSI is in neutral, overbought, or oversold territory.”
Automated trading signal monitor
“Check the BTC brief and tell me if the trend score and RSI suggest a neutral, bullish, or bearish posture — I want to decide whether to rebalance today.”
Sentiment-aware market summary
“I'm writing a quick crypto update — what's the current Bitcoin fear & greed index, sentiment classification, and how much has BTC moved in the last 24 hours and 7 days?”
Technical details
Endpoint
GEThttps://x402-research-iota.vercel.app/api/brief/btc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a compact, all-in-one Bitcoin market snapshot including technicals (RSI, SMAs), trend signals, and sentiment (fear & greed index) in a single cheap call ($0.03 USDC). Prefer it over general market data APIs when you want pre-computed trend classification and sentiment bundled together without assembling multiple data sources yourself.
Side effects
- Payment not completed or x402 authorization fails — endpoint returns 402 Payment Required
- Upstream price/sentiment data provider is unavailable — may return stale or error response
- Malformed request or unsupported asset path — returns 404 or 400
- Network timeout from Vercel serverless cold start — retry typically resolves
