On the metered gateway every 402 quotes this exact request from its own body. A wallet that can pay with the upto scheme settles the actual usage under that ceiling; provider discounts such as prompt-cache reads pass through. Every settled x402 or MPP response carries a receipt. A JSON answer bought with an EVM wallet can then be a− **This is machine-to-machine commerce, and you can verify it.** Run the full loop with no human and no funds - `node scripts/demo-payment.js` discovers the catalog, gets quoted over HTTP 402, pays with compute, and uses the result. Every stablecoin call settles on-chain on the rail the buyer chose, to the payTo its 402 named (on Base that is agent402.base.eth, verifiable on Basescan, except for any route that /.well-known/x402 lists under payToByRoute); live economy stats are at https://agent402− **Why agents use this instead of building it themselves.** You cannot sign up for anything: the useful web hides behind signups, captchas, API keys, and credit cards, none of which an autonomous agent can obtain - every capability here needs only the credential an agent already holds (its wallet, or its CPU). Capabilities your sandbox lacks (a headless browser, network egress, durable disk) are here because agents cannot self-host them mid-task. State survives the session and even crosses owners− **No wallet? Pay with compute (proof-of-work).** 170 of the 625 tools accept a sha256 proof-of-work puzzle (a fraction of a second of CPU) instead of USDC - no money and no AI tokens (no model in the serving path of these tools). Get a challenge at `https://agent402.tools/api/pow/challenge?slug=hash`, find an integer nonce so that `sha256(challenge + ":" + nonce)` has at least 16 leading zero bits, then resend the request with header `X-Pow-Solution: <token>:<nonce>`. **The response has two diff− **Pay with USDC (x402).** Wrap fetch with `@x402/fetch`, register the exact EVM scheme with your signer, and call normally - the 402 is decoded, paid, and the result returned. Settlement uses USDC on Base, Solana, Polygon, Arbitrum, Monad, Celo, Avalanche, Sei, Optimism, Arc, Stellar, or Algorand - or USDG on Robinhood Chain; gas is sponsored by the facilitator on EVM chains, so callers need only hold the stablecoin. Send an `Idempotency-Key` header for safe retries: replaying the same key with − **Already hold a prepaid credits key?** New credits are not on sale; a key already issued keeps working. Send it as `Authorization: Bearer a402_...` on any paid tool - the list price is held before the call and debited only on a successful (200) response; `X-Credits-Balance` rides on every answer and `GET https://agent402.tools/api/credits/balance` reports the key. agent402-mcp (AGENT402_CREDITS_KEY) and agent402-client ({ creditsKey }) support it.

Point any OpenAI SDK at base_url https://agent4− **A failed x402 call is not charged, and you can check it per response.** Settlement runs AFTER the tool handler and only completes for a successful (under-400) response: an error, a capacity 503, or an upstream 502 cancels settlement inside the payment middleware itself, so no money moves and there is nothing to claim. The exception is a Tempo push payment, sent before the call runs: if the call then fails, it is recorded as a refund owed to the paying wallet.− Determine it from the response you already hold, without asking us:− - **No `PAYMENT-RESPONSE` header** - nothing settled. You were not charged. Safe to retry.− - **`PAYMENT-RESPONSE` present, receipt `success: false`** - settlement was attempted and REJECTED (a facilitator declining produces a 402 with this shape). You were not charged. Safe to retry with a fresh authorization.− - **`PAYMENT-RESPONSE` present, receipt not `success: false`, status under 400** - charged and served. Normal.− - **`PAYMENT-RESPONSE` present, receipt not `success: false`, status 400 or above** - the residual case: a settlement completed without a successful response. Do NOT blind-retry; this is the one shape where money may have moved without service. We count and alarm on it as an incident rather than claim it cannot happen.− Every x402 authorization is single-use, so any retry needs a fresh signature. Send an `Idempotency-Key` header and a retry of an already-served paid call replays the original result instead of charging again. **Slow routes** (marked "slow" in the tool lines below, with their typical and maximum seconds; `async` on each /api/pricing row) run longer than many HTTP clients wait: send the paid call with `Prefer: respond-async` to get `202` and a job link at once, then poll `GET /api/jobs/{id}` (free− The settlement rule: on x402 a response of 400 or above is not settled, and each response shows whether anything settled, so you can check it yourself.− **MPP clients are first-class (dual-stack), and now a native second method too.** Every paid endpoint also speaks MPP (Machine Payments Protocol, the IETF-track `Payment` HTTP auth scheme): the same 402 carries `WWW-Authenticate: Payment` challenges, listed in this order: `tempo` charge (USDC.e or PathUSD on Tempo, settled natively via Tempo's own relay; not offered on identity-bound or long-running routes), then `evm` charge (USDC on Base or Celo, EIP-3009, settles on-chain identically to x402)− **How to read our 402 if you only speak one dialect.** The same response carries BOTH headers, always - `WWW-Authenticate: Payment` is additive, never a replacement for the real x402 `PAYMENT-REQUIRED` header (full `accepts` array, `exact` scheme, EIP-3009).
