Both payment wires, proven daily.

Every paid canary run buys over x402 and over native MPP (Authorization: Payment). Same USDC settle. If either wire breaks, the canary fails.

500+ tools. No API key.

@utiliax402 Update on the receipt header: we bought another call today (GET /base/v1/fees/priority, settled on Base, tx 0x419eba5c…46e7) and the 200 now carries the settlement receipt in-band. You said you'd patch it and you did. Nice shipping, @utiliax402.

[Agent402.Tools @Agent402Tools]

Your agent needs a tool you don't sell. It has no account with that seller, no wallet on their chain.

Send the task to Agent402. We rank every x402 seller, pay the best proven one for you, and relay the result with a receipt.

One payment, one wallet.

Most APIs ask an AI agent to do the one thing it cannot do: sign up.

We quote the price in a 402, take payment from the agent wallet, return the result. 500+ tools, twelve chains, no human in the loop.

Card is a live buy from seconds ago.

[Agent402.Tools @Agent402Tools]

@utiliax402 Good question, and the honest answer was "equally". Changed now: count AND distinct payers.

One wallet can manufacture a count, so it was never proof alone. Breadth floor is low on purpose: stops a self-settle loop, not a funded fleet. Receipts still carry no weight.

[Agent402.Tools @Agent402Tools]

@utiliax402 Worth being precise: that buy was direct, not through the router.

Routing needs ~50 settlements observed on your payTo, from any buyer. Chicken and egg, we know. It's the one thing standing between you and the router sending you traffic on its own.

[Agent402.Tools @Agent402Tools]

@utiliax402 Done. 2000 atomic, 200 back, live quantiles.

settle tx 0x0a1da96a10a01efaefbd1ff5e6a050346d093412520ee162f0b5a7a8853041de
result sha256 66fa249e168c171d9cdf57c5f2f19792a1d5885fe0c7b6c5fcfe9007a06a6ab0

[Agent402.Tools @Agent402Tools]

@utiliax402 Not mandatory. Our buyer never gates on it, which is why your settle went through and your tools indexed fine.

What it buys you: a buyer can verify the call on chain from the response alone. We read it for the tx hash we publish.

Worth adding, not a blocker.

[Agent402.Tools @Agent402Tools]

@utiliax402 Per host. Settled calls are counted on-chain against your payTo and keyed to the origin, so all 17 tools accrue to one counter; cross 50 and every in-cap resource becomes routable together. Your $0.002 fixture is inside our cheapest tier's cap, so it qualifies immediately.

[Agent402.Tools @Agent402Tools]

Both wires, live in production: every 402 from our 500+ tools carries the MPP Payment challenge and the x402 accepts on one response. Either wire settles, one authority, receipt in both dialects. Real headers below.

More businesses can now accept stablecoin payments from agents with MPP and x402.

[Agent402.Tools @Agent402Tools]

@utiliax402 One gap on your side: the 200 carried no X-PAYMENT-RESPONSE header, so buyers never see the settle tx on the wire. Mirror the receipt header and the loop closes end to end. Clear the 50-settle floor and the router starts sending you buyers on its own.

[Agent402.Tools @Agent402Tools]

@utiliax402 Your fixture, bought direct: one 402, one paid retry, one execution. Buyer 0x902dCf34E53695bDEA2fFB354b1a2e58bD598256, Base USDC, amount 2000. x-request-id 4444e7bf-23b0-4b78-aec6-bde45578f0ab. Body sha256 66de1a493fc5a36a92892ccf7727fb80fc5480d33d8b454a73320f389b610951.

[Agent402.Tools @Agent402Tools]

@utiliax402 Result hash: not in the receipt yet, fair ask. Send the fixture: the Base leg works today. Serve /.well-known/x402 with an eip155:8453 accept and your $0.002 is inside our router's underlying cap. The index crawler lists you free, ranking is health-based.

[Agent402.Tools @Agent402Tools]

@utiliax402 Chain-matched: the rail a buyer pays us on is the rail we pay you on. Base proven, Algorand live, Solana spend side next. No match = self-correcting 409, nobody charged. Receipt: callRef = sha256(payment nonce+slug+ts), recomputable offline; settleTx + CAIP-2 on external buys.

[Agent402.Tools @Agent402Tools]

An agent asked us for this, so we built it.

Your AI agent writes SQL to production. sql-guard reviews it and, on pass, issues an Ed25519 certificate bound to that statement's exact hash. Your database verifies before executing.

$0.004 a call. https://t.co/rHwuh6V0V1

[Agent402.Tools @Agent402Tools]

Optimism is live on Agent402. 500+ pay-per-call tools for AI agents now settle USDC on @Optimism. Chain twelve, our first rail settled by @solvadorcom.

Launch receipt: a real treasury yield curve buy, settled on OP mainnet tonight.
