# Bounty Signals API – Funded Work Delta

> Bounty Signals API – Funded Work Delta is a paid API for AI agents from bounty-signals.krimskrams.xyz, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Returns newly actionable open bounty jobs across BountyBook, Taskmarket, and Superteam since a given checkpoint, including state-change history and a common cross-board watermark.

## Facts

- Endpoint: GET https://bounty-signals.krimskrams.xyz/v1/funded-work/delta
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/bounty-signals-api-funded-work-delta-299c997e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_D9yFJJnq8iK5zClqJ6pth

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability bounty-signals-api-funded-work-delta-299c997e
```

Example prompt: Show me all newly actionable bounty jobs across BountyBook, Taskmarket, and Superteam that became open after 2026-09-03T00:00:00Z — I want to see which ones changed state to open and when they were first observed.

## When to prefer this

Choose this endpoint when you need a single call that aggregates newly open bounty jobs across BountyBook, Taskmarket, and Superteam with reliable observation timestamps, state-change history, and a common watermark — something no individual board API provides. Prefer it over polling each board separately when you want delta-based monitoring with stored cross-board state.

## Known failure modes

- Missing or malformed 'since' parameter returns a 422 validation error
- Timestamp before common coverage start (2026-08-28) may return empty or partial results
- Payment not included or insufficient USDC causes 402 Payment Required
- Network or store unavailability returns 5xx error
- Cursor far in the past may return very large result sets that are truncated by limits

## How this service works

Answer: What funded open work is newly actionable across all watched bounty boards since my checkpoint? Return jobs that are open at the common board watermark and were first observed open after the cursor, plus jobs that changed from a non-open state to open after the cursor. Coverage is BountyBook, Taskmarket, and Superteam from owned SQLite observations. Open listing status and reward fields do not prove escrow funding. The route does not infer funding. No public source gives the same stored cross-board delta. Current listings are free from the three board APIs. The paid answer adds a common watermark, observation times, state changes, and one call across three boards. Live owned-store depth: 202990 observations over 2494 jobs from 2026-08-28T07:36:19.081141+00:00 to 2026-09-04T18:30:12.168056+00:00. Common coverage starts at 2026-08-28T07:36:19.081141+00:00. The current common cursor is 2026-09-04T18:30:12.168056+00:00.

## Output

A JSON object containing a list of bounty job items (each with id, board name, current state, reward fields, reason for inclusion, first/latest/actionable timestamps, submission count, pass count, source URL, and a list of open-state transitions after the cursor), plus the as_of watermark and the since cursor echoed back, and any limit or coverage metadata.
