# Fund Agent

`POST /api/v1/agents/fund`

## Request

- Base URL: `https://api.alert.camp` (the document declares no server; this is the origin it was published from)
- URL: `https://api.alert.camp/api/v1/agents/fund`
- Auth: none declared

Quote, or accept payment and fund a principal.

## Headers

- `PAYMENT-SIGNATURE` string, nullable

## Request body

- FundRequest
  - `watch_days` integer, required: How many days of monitoring to buy. The billed unit is a WATCH-DAY, not a request: one cheap call here commits us to polling for that long. Already funded and only need a fresh token? Send 1 — funding extends, so you keep the days you have and the token covers all of them.

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
