# Venice x402 (wallet credits)

x402 is Venice's **wallet-based payment** flow. Prepay USDC on Base or Solana mainnet into a wallet credit balance, then authenticate each request with a signed Sign-In-With-X (SIWX) proof — no Venice account or API key required. Three wallet endpoints plus the protocol-level `402` responses.

| 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 credit balance for a wallet. |
| `GET /x402/transactions/{walletAddress}` | SIWX | Paginated ledger: `TOP_UP`, `CHARGE`, `REFUND`. |

For the SIWX header format itself, see [`venice-auth`](../venice-auth/SKILL.md).

## Header names

Send the canonical name in new code; the others exist so older integrations keep working.

| Purpose | Canonical | Also accepted |
|---|---|---|
| Signed payment (top-up settlement only) | `PAYMENT-SIGNATURE` | `X-402-Payment` (Venice original), `X-PAYMENT` (x402 v1 / `x402-fetch`, `x402-axios`) |
| Wallet sign-in proof | `SIGN-IN-WITH-X` | `X-Sign-In-With-X` (Venice original) |
| Payment requirements (response) | `PAYMENT-REQUIRED` | — |
| Settlement result (response) | `PAYMENT-RESPONSE` | — |
