How this service works
Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.
Output
A normalized JSON response containing current exchange rate(s) for the requested cryptocurrency pair(s), sourced from public market data providers with edge-caching and multi-source fallback applied.
Example use cases
Real-time BTC price check
“What's the current Bitcoin to USD exchange rate right now? Use that keyless crypto data API that charges a cent per call.”
DeFi bot price feed
“Fetch me the latest ETH/USDC exchange rate so my trading bot can decide whether to rebalance — I need a fresh price without setting up any API accounts.”
Portfolio valuation snapshot
“I need the current exchange rates for BTC and ETH in USD to calculate the value of my crypto holdings — grab them from the pay-per-call data source.”
Technical details
Endpoint
GEThttps://x402.santyvv.com/api/crypto/exchange-rates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptocurrency exchange rates without signing up for an account or managing API keys, and are comfortable with micropayment-per-call billing in USDC on Base via x402. Ideal for agents that need occasional price lookups rather than high-frequency streaming, and for scenarios where keyless, friction-free access is the priority.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Invalid or unsupported currency pair — returns error with no rate data
- Upstream data provider outage — may return stale cached data or error
- Malformed query parameters — returns 400 Bad Request
