x402 facilitator support: schemes and networks
An x402 seller names a payment scheme and network in every 402 response, and a facilitator verifies and settles the buyer's signed payment. A scheme only works if the seller's facilitator settles it on that network. This table reads each facilitator's own /supported endpoint, mainnets only. Fetched 2026-10-10 04:09 UTC.

exact: a fixed price per call. upto: the buyer signs a maximum and the seller settles the actual amount (on EVM this uses Permit2). batch: batch-settlement, where the buyer funds an escrow once and signs off-chain vouchers that the seller redeems in groups. “(v1)” means the facilitator lists the network only under an x402 v1 name. A dash means the facilitator does not list that scheme on that network; other schemes some facilitators list (such as bridge) are left out. A column of dashes means that facilitator lists only testnets or networks outside this table.

Extensions are optional features. bazaar means the facilitator catalogs paid endpoints for discovery. eip2612GasSponsoring and erc20ApprovalGasSponsoring cover the token approval that upto needs, so the buyer does not pay gas for it. The Coinbase CDP endpoint needs an API key; its column comes from an authenticated call made at the same time.
What sellers should check
- Before offering
uptoorbatch-settlement, confirm your facilitator lists that scheme on the network you charge on. Not every facilitator that lists a network lists every scheme on it. - For context, State of the x402 Bazaar counts how many Bazaar listings offer each scheme.
- Tanod charges
exactin USDC on Base, Polygon and Solana through Coinbase CDP. You can check any x402 endpoint before paying it.
