两个新端点的单个请求定价为0.0005 USDC，通过Base网络结算。
The recalibration service is billed per use, uses USDC on the Base chain, and settles through the x402 payment protocol.
Across Base, Optimism and Ethereum mainnet, the EAS protocol shows that 733,203 of 4,986,045 attestations have been revoked, a revocation rate of nearly 15%.
On Base, three schemas (verifiedAccount, verifiedCountry, verifiedCoinbaseOne) account for 97% of all revocations, and all belong to the same issuer, Coinbase.
EAS has official deployments on Base and Optimism mainnet, and has spawned indexers like easscan.org that aggregate on-chain logs into a queryable GraphQL interface.
On the Base chain, the EAS indexer shows that 678,895 of 3,651,900 attestations have been revoked.
The x402 payment network supports three chains: Base, Solana and Arc.
Among x402's cumulative transaction volume, Base ranks first with 85,057,200 transactions, followed by Solana and Polygon.
The payment field in a real unpaid 402 response contains: scheme: exact, network: eip155:8453 (Base), asset: USDC contract address, amount: 10000 (i.e. 0.01 USDC), payTo: receiving address, maxTimeoutSeconds: 120.
Reply Desk exposes a machine-readable /templates.json interface via the x402 payment protocol on the Base chain in USDC, charging $0.50 per fetch, with no account or API key required.

x402 is an open protocol that reuses the 402 status code (Payment Required) from the HTTP protocol, enabling software (especially AI Agents) to call APIs on a per-request pay-as-you-go basis and settle directly with cryptocurrency (typically USDC), without requiring accounts, API keys, or traditional checkout pages.

50%UnverifiedThe core reason for choosing Base L2 over the Ethereum mainnet is that micropayments are extremely sensitive to gas costs, and mainnet fees could far exceed the value of a 0.05 USDC transaction itself.
50%UnverifiedIn the experiment, after the agent requested a data endpoint and the server returned a 402 challenge, the agent autonomously signed a micropayment transaction of 0.05 USDC on the Base L2 network and then obtained the data.
50%UnverifiedBase is an Ethereum Layer 2 network built on the OP Stack and launched by Coinbase in 2023.
50%UnverifiedThe gas fee for a single USDC transfer on Base is typically less than $0.01.
50%UnverifiedOn-chain settlement for x402 relies primarily on Ethereum L2 networks such as Base to reduce the gas cost per transaction.
