Rolling-window metrics for the PayPerByte x402 facilitator: verify/settle counts, per-network/scheme breakdowns, top payers, optional on-chain cross-check.
Output
A JSON payload containing the x402-pulse feed data, cryptographically signed and EIP-712 PayloadAttestation provenance-stamped, returned after a USDC micropayment (~$0.0146) is settled on Base (eip155:8453). Includes feed name confirmation and the signed data blob.
Example use cases
Example prompt
“Fetch me the latest x402-pulse feed from BYTE Library — I need the cryptographically signed, EIP-712 provenance-stamped payload and I'm paying with USDC via x402 from my wallet on Base.”
Technical details
Endpoint
GEThttps://x402.payperbyte.io/feeds/x402-pulseWhen to prefer
Choose this endpoint when an AI agent needs verifiable, tamper-evident data with cryptographic provenance (EIP-712 attestation) for the x402-pulse (code activity / developer metrics) feed, and prefers wallet-based micropayment over API-key management. Ideal for trustless agent pipelines where data authenticity must be auditable on-chain.
Side effects
- Insufficient USDC balance in wallet — payment rejected, 402 response
- Wallet not configured or invalid address — authentication failure
- Feed temporarily unavailable — 5xx server error
- Malformed x402 payment header — 400 bad request
- Network congestion on Base causing payment settlement delay
