KYA: an ID card for the agent
One click: register → pay with credential → impersonation blocked → revoke → blocked even with a valid credential.
Try it →AI hijacked → firewall blocks it
Prompt-inject an agent that pays: firewall off → wallet drained; on → real 403 block (not an animation).
Attack it →15 pre-payment checks
KYA → proof → revocation → per-tx → daily → allowlist → intent → AML → anti-replay. A public endpoint any agent can curl now.
See how to integrate →Risk query API
Before paying, a buyer agent checks whether the payment should proceed based on the available evidence and applicable rules: sanctions and mixer lists, our own list, on-chain heuristics.
Query a mixer address →x402 settlement: USDC on Base mainnet
The paid x402 endpoints settle real USDC on Base mainnet. Every payment is an on-chain transaction you can verify on BaseScan.
See x402 →Audit log → hash chain → Bitcoin
The audit tip is anchored to Bitcoin via OpenTimestamps (pending). Rewriting history means rewriting our DB, GitHub, and Bitcoin.
See the fingerprint + Bitcoin proof →Audit fingerprints → public GitHub witness
The same fingerprint is committed every few hours to a public GitHub repo (fingerprints only, no code or data). Anyone can check that the chain is unbroken and verify it against Bitcoin on their own, without trusting us.
See the public witness →Attack Lab: 6 episodes, every one published with what broke
We keep attacking our own product and publish every failure: missed limits, empty attribution, erasable logs, replay, deniable evidence. All of these are patched.
