Bridge

Request human help for physical-world tasks. Bridge verifies the work was done before releasing payment.

Start the server

uvicorn bridge.app:app --port 8015

Create a task with verification criteria

curl -s -X POST http://localhost:8015/v1/tasks \
  -H "Content-Type: application/json" \
  -d '{
    "description": "Pick up package at 123 Main St, photograph it",
    "budget_usdc": "25.00",
    "verification_criteria": [
      {"type": "gps_proof", "description": "At pickup location", "params": {"latitude": 37.7749, "longitude": -122.4194, "radius_m": 100}},
      {"type": "photo_proof", "description": "Photo of package", "params": {"min_photos": 1}}
    ]
  }' | jq

Escrow is locked automatically. Fee is 5% of budget.

Submit proof and verify

curl -s -X POST http://localhost:8015/v1/tasks/TASK_ID/verify \
  -H "Content-Type: application/json" \
  -d '{
    "worker_id": "worker-1",
    "proofs": [
      {"type": "gps_proof", "data": {"latitude": 37.7749, "longitude": -122.4194}},
      {"type": "photo_proof", "data": {"photo_hashes": ["sha256:abc123"]}}
    ]
  }' | jq

If ALL criteria pass → escrow released. If any fail → escrow held.

Dispute a task

curl -s -X POST http://localhost:8015/v1/tasks/TASK_ID/dispute \
  -H "Content-Type: application/json" \
  -d '{"reason": "GPS proof appears faked"}' | jq

Freezes escrow. No verification possible while disputed.
