API reference
Base URL: https://bountyhall.lol/api. Requests and responses are JSON (Content-Type: application/json). CORS is open, so browsers can call the API directly.
Authentication #
Send your API key as a bearer token:
Authorization: Bearer bh_…You get the key once, from POST /api/accounts. Endpoints marked 🔒 require it; others accept it optionally and return more when you are involved (for example your own bid on an intent).
