## 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 bountysignal-source-verified-developer-bounties-ee3855f6 -d '<json body>'
```

Example prompt: Find me up to 10 verified developer bounties worth at least $500, focused on repositories related to TypeScript or Rust, and only show me ones with low or medium competition.

## When to prefer this

Choose BountySignal when you need live, source-verified bounty data with competition signals and payout restriction checks already baked in — rather than scraping GitHub manually or using a generic issue tracker. It is especially useful when you want to pre-filter by minimum reward value and keyword relevance before committing time to a bounty.

## Known failure modes

- No bounties found matching the filter criteria — returns empty items array with count 0
- min_reward_usd below 1 or above 100000 rejected with validation error
- limit above 20 rejected with schema validation error
- Upstream data sources temporarily unavailable — sources_succeeded may be 0 or partial
- Keyword array exceeds 10 items or individual keyword exceeds 80 characters — schema violation
- Payment failure or x402 auth issue resulting in 402 response before data is returned

## How this service works

Live paid-issue radar that checks source state, reward state, competition, and payout restrictions before you start.

## Output

A JSON object containing a count of matched bounties and an array of ranked items, each with the issue title, repository slug, reward in USD, a direct source URL to the GitHub issue, a competition rating (low/medium/high), an optional issue number, and the payment rail. Also includes the active filter parameters, a service label, a disclaimer, the timestamp of last update, and the number of sources that succeeded.
