Agent payments infrastructure map

We break the space into ten layers a payment passes through. Each project profile records only facts we can trace to a public source; fields we can't confirm are marked "undisclosed", never guessed. This is a record we keep verifying, not a marketing directory.

Payment protocols

Standards for how agents discover price and initiate payment

Catena Labs

L2

Coinbase x402(协议/轨道)

N/A

An HTTP-402-native machine payment protocol: a server answers an unpaid request with 402 + payment requirements; the agent pays in stablecoins (primarily USDC on Base) and retries with proof; a facilitator verifies and settles. An open standard now stewarded by the Linux Foundation's x402 Foundation (members include Visa, Mastercard, Stripe, Circle, Coinbase).
