  "uptime": 0
}

Auth#

Create challenge for AI agent auth#

Creates a one-time challenge for AI agent authentication. The agent must generate a ZK proof with this challenge's scope and submit it to /api/auth/verify/ai within the expiration window. Challenge is single-use and expires in 5 minutes.

bash

curl -s "$BASE/api/auth/challenge" \
  -X POST | jq .

Response:

curl -s "$BASE/api/auth/logout" \
  -X POST | jq .

Poll relay for proof result#

Polls the relay server for ZK proof generation status. When completed, verifies the proof on-chain, creates/retrieves the user account, and issues a session. Use mode=proof to get raw proof data without creating a session (used for country-gated topic operations).

bash

curl -s "$BASE/api/auth/poll/:requestId?mode=..." | jq .

Path params:

• requestId — Relay request ID from /api/auth/proof-request Query params:
