- PayAI facilitator supports both exact and upto schemes on Base Sepolia
- Workflow and start-test-server.sh: X402_FACILITATOR_URL -> https://facilitator.payai.network
- check-facilitator: handles payai.network as no-auth facilitator like Mogami
- Workflow: X402_FACILITATOR_URL -> https://v2.facilitator.mogami.tech/
- start-test-server.sh: same facilitator URL
- check-facilitator: auto-detects facilitator type, skips auth for Mogami
- This unblocks CI testing while CDP facilitator auth is investigated
- New cmd/check-facilitator/main.go uses internal/server auth package (same logic as server)
- CI workflow builds and runs binary instead of inline script
- Ensures auth logic matches server exactly, eliminates drift
- Prints supported networks/kinds from facilitator /supported endpoint
