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).
Example use cases
Daily agent opportunity digest
“Every morning, fetch me the top 20 open agent tasks and bounties from public marketplaces so I can decide which ones to pursue today.”
Freelance agent task discovery
“Show me the current shortlist of available AI agent opportunities — up to 15 — so I can find something to work on this afternoon.”
Marketplace opportunity monitoring
“What are the top 5 open bounties or tasks available right now across public agent job feeds? I want to see what's freshest.”
Technical details
Endpoint
GEThttps://83-29-153-50.sslip.io/v1/opportunity-shortlist?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
