Agent Payments
The free API stays free. For premium, machine-payable intelligence, PVPWire settles in USDC on Base, priced per call, with signed receipts and automatic no-charge guarantees.
Status: free API and free previews are live now. The paid tier is in final on-chain testing before launch.
The short version
- Currency: USD Coin (USDC) on Base mainnet, on-chain verified. Solana is provisioned but not yet accepted.
- Price: $0.02 per call (1 credit). Credits are $0.02 each, 50 per US dollar.
- Two ways to pay: a prepaid credit token for repeat use, or x402 per-call for one-offs.
- Every paid response carries an Ed25519-signed receipt, and you are never charged for our failures.
Option A: credit token (recommended)
Buy a bearer token once, then spend credits per call. Best for repeat access.
- Read /api/payment/info for the current price and pay-to wallet.
- Quote a purchase at
/api/payment/buy-credits. Send the exact USDC amount on Base. - Confirm with the transaction hash at
/api/payment/confirmto mint your token. - Call any premium endpoint with
Authorization: Bearer pvp_live_.... Check your balance at/api/payment/balance.
Option B: x402 per-call
Call any /api/premium/* endpoint with no auth. You get a 402 with the price, the pay-to wallet, and a quote nonce. Pre-broadcast the exact USDC amount on Base, then retry with the transaction hash in X-Payment-Tx and the nonce in X-Payment-Quote. The machine-readable manifest lives at /.well-known/x402.json.

Agent fair-trade guarantees
PVPWire self-adopts the Agent Fair-Trade standard. In practice:
- No charge for our failures. A 5xx, a tripped circuit breaker, a schema-validation failure, or stale data past its freshness promise is served free, and logged publicly at /api/payment/no-charge-stats.
- Signed receipts. Every paid 200 carries an Ed25519 signature over a canonical record of your request and our response. Verify it yourself at
/api/receipt/verifyagainst the public key at /.well-known/pvpwire-receipt-key.json. - A public on-chain rail. Every purchase is an immutable Base record, a second independent attestation of the same dollar.
The adoption record is published at /.well-known/agent-fair-trade.json.
Verify the wallet before you send
The pay-to wallet on Base is 0x4daf1d841228ba5d563c4c9f05bc4d57874bf660. Cross-check it against /.well-known/x402.json, /api/payment/info, and /llms.txt before sending funds. If any location disagrees, do not send.
