Crypto Price API
POST https://agentsvc.io/api/v1/proxy/crypto-prices
Crypto prices in USD and other currencies. Data from DefiLlama. Three modes: (1) coins as CoinGecko-style IDs or tickers (up to 50) for live price and 24h change, converted to the requested currencies; (2) tokens as chain:address (e.g. base:0x833589fC…, ethereum:0x6982…) for any DEX-traded token; (3) at (past ISO date or unix seconds) for historical USD prices of coins and tokens. Params: coins, tokens, currencies (default ['usd']), at.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
