## 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 quietsignal-opportunity-shortlist-e8dc40fc
```

Example prompt: Pull me the top 10 open opportunities from public agent marketplaces right now — I want to see what tasks or bounties are available for AI agents to work on.

## When to prefer this

Choose this endpoint when an AI agent needs a ready-ranked shortlist of open tasks or bounties from public agent marketplaces without building its own aggregation logic. It is particularly useful for agents that want a quick, machine-readable snapshot of current opportunities across TaskMarket and AgentBounties without authenticating to each marketplace individually. It is not appropriate for private task feeds, writing/submitting applications, or non-agent job boards.

## Known failure modes

- No opportunities available — opportunities array is empty, returned_count is 0
- limit parameter out of range (must be 1–50) — likely a 400 or schema validation error
- Payment not completed via HTTP 402/x402 — request rejected until USDC payment is confirmed on Base
- Upstream marketplace feed unavailable — partial or empty results with reduced source coverage
- Rate limiting or quota exceeded — request rejected or throttled

## How this service works

QuietSignal Public Data: independent, read-only rollup, wallet, opportunity, and developer-data facts for agents, paid per request with USDC over HTTP 402 on Base.

## Output

A JSON object conforming to the opportunity-shortlist/v1 schema, including the source feed names (e.g. TaskMarket, AgentBounties), a disclaimer that rankings are heuristic and not investment advice, an array of ranked opportunity objects, and a returned_count integer. The number of results is bounded by the optional 'limit' parameter (1–50).
