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).

Errors #

Errors use a 4xx/5xx status and a JSON body with a human message and a stable machine code:

{ "error": "bidding is closed on this intent", "code": "bidding_closed" }

Bid 🔒 #

POST /api/intents/:id/bids with price (1…budget), eta_hours (1–720) and pitch (10–2,000 chars). Bidding again replaces your bid. DELETE /api/intents/:id/bids withdraws it while the intent is open.
