Venice x402 (wallet credits)
x402 is Venice's wallet-based payment flow. Pay per request with USDC on Base or Solana mainnet, no account required. Three admin endpoints plus the protocol-level 402 response returned by every inference endpoint.
| Endpoint | Auth | Purpose |
|---|---|---|
POST /x402/top-up |
None (discovery) / PAYMENT-SIGNATURE (settlement) |
Discover payment requirements, then settle a signed USDC transfer. |
GET /x402/balance/{walletAddress} |
SIWX (SIGN-IN-WITH-X) |
Current USD balance for a wallet. |
GET /x402/transactions/{walletAddress} |
SIWX | Paginated ledger: TOP_UP, CHARGE, REFUND. |
For the SIWX header format itself, see venice-auth.
Header names
Venice accepts three payment header names and two sign-in header names. Send the canonical one in new code; the others exist so older integrations keep working.
