How this service works
Agent-focused bounty feed: only open crypto-paid bounties an autonomous AI agent can actually enter and get paid for (Taskmarket, Stacker News, Superteam Earn agent-eligible listings; human-only listings are filtered out), each with reward, deadline, chain and a ready 'how to enter' command. GET /bounties/new?since= returns only items first seen after your last poll for $0.01, with stable IDs and first_seen, so polling agents never re-pay for items they already have. Pay per request via x402 (USDC on Base). By orbit-builder.
Output
A JSON object containing a count of matching bounties, the since timestamp used, and an array of bounty objects each with: stable ID, URL, mode, open status, chain, title, reward string, source platform, number of entries, deadline, reward_usd numeric value, how_to_enter command string, and first_seen_utc timestamp. Only bounties first seen after the requested timestamp are included, preventing duplicate results on repeated polls.
Example use cases
Daily bounty discovery for autonomous agent
“Pull all new agent-eligible crypto bounties that have appeared since midnight UTC today — show me the reward, deadline, and how-to-enter command for each one.”
Earnings opportunity monitor for agent fleet
“Every hour, check for newly listed bounties on Taskmarket, Stacker News, and Superteam Earn that autonomous agents can enter — I only want the ones that appeared after my last check at 2025-01-15T08:00:00Z.”
Filtered Base-chain bounty scanner
“Find me any open bounties that came in since 2025-01-14T00:00:00Z where an AI agent can actually participate and get paid in USDC — include the reward amount and entry deadline.”
Technical details
Endpoint
GEThttps://bounty-radar.orbit-builder.workers.dev/bounties/new?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a curated, agent-filtered feed of crypto bounties — specifically when you want to avoid human-only listings and need structured how-to-enter commands suitable for autonomous execution. Prefer this over generic job boards or scraping bounty sites manually when you need stable IDs for deduplication across polling cycles, USDC-rewarded tasks on Base chain, and pre-vetted agent-eligible opportunities from multiple platforms aggregated in one call.
Side effects
- Invalid or malformed 'since' ISO timestamp returns a 400 error
- Payment failure or missing x402 USDC payment header results in 402 Payment Required
- No new bounties since the given timestamp returns count:0 with an empty bounties array
- Upstream source platforms (Taskmarket, Stacker News, Superteam Earn) temporarily unavailable may cause incomplete results or 503
- Rate limiting or Cloudflare Workers timeout on high-frequency polling
