How this service works
Verified, provenance-first data feeds for AI agents. Every payload is cryptographically signed and EIP-712 PayloadAttestation provenance-stamped — covering crypto markets, DeFi yields, weather, earthquakes, news, code-pulse, threat-intel, and a slashable fact-oracle. Pay per call in USDC over x402 with no API keys — a wallet, not a secret on the box. Settlement is on Base (eip155:8453). Price is per-feed, derived from expected payload size at $0.005000/KB (floor $0.001000).
Output
A JSON payload containing Bitcoin market metrics (e.g. price, volume, related indicators) for the 'btc-metrics' feed, accompanied by a cryptographic signature and an EIP-712 PayloadAttestation provenance stamp confirming data integrity and origin.
Example use cases
Example prompt
“Pull the latest Bitcoin metrics from the BYTE Library provenance-signed BTC feed — I need verified, attested data and I'm happy to pay the per-call USDC fee via my wallet.”
Technical details
Endpoint
GEThttps://x402.payperbyte.io/feeds/btc-metricsWhen to prefer
Prefer this endpoint when your agent pipeline requires cryptographically verifiable, provenance-stamped Bitcoin market data and you want to avoid API key management in favor of wallet-based micropayments. Ideal for trustless or auditable agent workflows where data authenticity must be provable on-chain via EIP-712 attestation.
Side effects
- 402 Payment Required — wallet has insufficient USDC balance or payment not submitted
- Invalid or expired x402 payment header — settlement rejected by Base
- Feed unavailable or upstream data source error — returns error JSON
- Malformed request properties — schema validation failure
- Network timeout from x402.payperbyte.io
