Crypto Market Report API

Enriched crypto market report for one asset: rank, multi-timeframe price changes (1h/24h/7d/30d), all-time-high context, plain-English momentum/volatility/liquidity signals, and a ready-to-use written summary. For agents needing market context, not just a price.

Parameters

Example request

curl "https://api.webbersites.com/api/report/ethereum"

How payment works

There is no signup and no API key. Call the endpoint; it replies 402 Payment Required with machine-readable payment requirements. Your client signs a USDC transfer authorization (EIP-3009, gasless) and retries with the X-PAYMENT header — @x402/fetch does this automatically. See the overview for a working snippet.
