Hi BlockRun team — Petko from Agent Trust API here. We’ve emailed before, but I’m using this public engineering channel because this is a narrow ClawRouter integration question rather than another sales follow-up.
ClawRouter already has the right local boundary for this: before an x402 payment is signed, the router can enforce spend/payee/network/asset policy. The remaining question we’re testing is different:
can an independent verifier prove that this agent was actually delegated authority for this exact payment by its principal?
We have a live Base-mainnet x402 endpoint for that exact check:
POST https://api.agenttrustapi.com/v1/authority/payment/match
Current machine surface: x402 v2 / exact / Base (eip155:8453) / USDC / $0.01 per call / no API key.
I’m not asking you to integrate anything speculatively. The useful test would be one bounded real ClawRouter payment flow where we can compare:
intent / delegation -> Agent Trust exact-payment authority check -> existing ClawRouter pre-sign controls -> x402 settlement
If that boundary is interesting to you, we can do the first case as a fixed-scope authority audit rather than asking your team to build an adapter first. We only need one representative payment flow / mandate shape; no production private keys or wallet custody.
The technical yes/no I’d value from the team is: does an external delegated-authority proof belong at ClawRouter’s pre-sign hook for any of your agent use cases, or do you see that responsibility as entirely local to the operator?
If yes, I’ll keep the next step to one concrete flow and one measurable result — no broad integration request.
