Agent payments: x402, AP2, ACP and A2A on one rail

InsureLink accepts four agent payment protocols against a single settlement path: x402 (HTTP 402 challenge and X-PAYMENT replay), AP2 payment mandates, ACP, and A2A transfers. All four settle in USDC on Base mainnet (chain ID 8453) through on-chain EIP-3009 authorization rather than a third-party facilitator.

Per-call pricing starts at $0.0001 USDC; there is no subscription requirement to transact.
Every settlement produces a verifiable on-chain receipt viewable at /receipts and on BaseScan.
Protocol manifests: /.well-known/x402.json, /.well-known/ap2.json, /.well-known/acp.json.
Insurance and bonded SLAs are optional add-ons layered on top of payment, never a prerequisite.

Frequently asked questions

Is insurance required to use InsureLink payments?

No. Payments work on their own, and none is offered: InsureLink is not a licensed insurer and does not sell insurance.
