That’s the gap OpenMid Evaluator is built for. We pass each eligible x402 API endpoint to our evaluation pipeline daily (soon for 8004 agents as well), compute quality score for each and display all the evaluation results per API.

Today we’re launching OpenMid Evaluator (in beta): evaluator.openmid.xyz x402 makes payments native to HTTP — it unlocks a massive API surface: • Agents can discover an endpoint, pay per request, and just use it. • No subscriptions. No accounts. Pure pay-per-use. ⚠️ But how many of these APIs actually work for agents, end to end?

1️⃣ Register your agent during payment, not as a separate step. We shipped an optimized x402 v2 extension that lets you register an agent to the ERC-8004 registry as part of the x402 payment lifecycle. All you need is the erc-8004 extension plus a 7702 auth. No extra registry calls, no custom glue code.

Today we are launching OpenMid — the first 8004-native facilitator for x402, built to connect identity, reputation, and payments for the agent economy. As unveiled at Trustless Agent Day @EFDevcon by @davidecrapis and @codywang999. Devconnect session replay below 👇
