x402

Per-call micropayment protocol (HTTP 402) for APIs and data. Not a cart checkout.

What it is. A server quotes a price with HTTP 402; the client pays and retries the same request. No cart, no checkout page. Source: research/x402.md (483 rows, snapshot 2026-10-31, last reviewed 2026-10-31).

Who maintains it. Coinbase (CDP) publishes the protocol and a reference facilitator. Open governance via the x402 Foundation / Linux Foundation.

What it is not. Closest to MPP (both charge per request). Distinct from AP2 and ACP, which authorize purchases.

Note. Price and network only when the table has them. An em dash means omitted.

Price, network, and status only when the table has them. Compare rails: x402 vs AP2 vs ACP vs MPP · PAP. Full x402 table (Spanish): /x402/. All listings A–Z: /en/directory/.

• 2026-10-31. CDP Bazaar cross-check of 2026-10-31 (per CDP, 107,089 resources on 3,106 hosts, 28,997 without market.datapackvibe.com): RallyLive Intel becomes doubtful, because its host left the Bazaar and only other subdomains of the same domain remain, and Driftflight is no longer listed. In the LupaRiel re-probe Driftflight returned 401 with no payment challenge. Both fichas stay. Stablecoin Gateways offered XRP in its 402 again, always conditional on the quote.

Corrections to the previous cut after Scout's answers: FindMyDirectDoctor charges 0.01 to 0.05 USDC depending on the route, Stablecoin Gateways charges on XRPL only when it has a quote (on 2026-10-30 the 402 withheld it and offered only USDC on Base), HCRB confirms its Solana accept and AgentShelf is marked unstable, with no response since 2026-10-29.

HEAD now pays when the route is configured for GET (#3796) and the OPTIONS preflight no longer gets a 402 (#3738). Go adds EVM auth capture on the server and facilitator (#3622). The same day an exact scheme for Canton Network is merged (#3242, docs in #4031), but @x402/canton is not on npm yet.

• 2026-10-29. The CDP Bazaar lists 93,505 resources across 2,843 hosts as of 2026-10-29. market.datapackvibe.com accounts for 64,781 and is left out of the totals, so without it there are 28,652 resources (709 fewer than on 2026-10-28). 106 hosts join, 69 of them from an x402-v2-mint batch on vercel.app, and 42 leave. AgentShelf is no longer listed in the Bazaar and Strale is now doubtful: the service name matches, the host does not. AgentShelf ficha · Strale ficha

• 2026-10-28. Celo adds Ripio's wMXN, wCLP and wPEN plus cNGN to its x402 facilitator, which already had wARS, wBRL and wCOP, for 10 stablecoins in total. AR Data Agent is still the only seller in the catalog that charges in wFIAT. The CDP Bazaar lists 93,136 resources across 2,779 hosts as of 2026-10-28. market.datapackvibe.com accounts for 63,775 and is left out of the totals, so without it there are 29,361 resources.

The example facilitators stop returning 500 on invalid requests (#3936) and the Python one reads requirements by x402 version (#3934), which closes bugs #3928 and #3929.

• 2026-10-23. Security: on 2026-10-22 V12 published a review of the x402 code with 25 flaws, 3 of them critical. (1) The default client had no spending limit: a hostile API could ask for the full balance of a supported token. (2) The TypeScript Solana facilitator accepted a token approval, which moves no funds, as a payment. (3) The client signed SIWx login messages for a site other than the one that sent the 402. Per The Hacker News, all three were fixed in the 2026-08-18 releases: use @x402/fetch or @x402/axios 2.23.0 or later, @x402/extensions 2.23.0 or later if you use SIWx, and @x402/svm 2.23.0 or later on Solana facilitators.

The product builds on x402: a business gives the agent a task and a budget, on a 402 the agent signs a payment voucher within that limit, the provider verifies it and delivers, and vouchers are combined and redeemed later, off-chain. Pilots: Cloudflare, Ant International, AIsa, Base, BVNK, Coinbase, and Hype. In the demo, Hype made 9 payments to 2 merchants (AIsa and Cloudflare, with the 402 served through Cloudflare Monetization Gateway) under one budget. Coinbase Developer Platform provides the wallet, Base settles on-chain, and BVNK handles payment and settlement in fiat or stablecoins on the Mastercard Global Money Platform.
