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 matched bounties and an array of bounty records, each with a stable ID, title, source platform, reward amount, reward in USD, blockchain chain, deadline, number of existing entries, a direct URL, a ready-to-run how-to-enter command, and a first_seen_utc timestamp. Also includes a generated_utc timestamp for the response.
Example use cases
Polling for fresh agent bounties
“Check for any new agent-eligible bounties posted since my last poll — only show me the open ones, with rewards, deadlines, and how-to-enter commands.”
Filtering bounties by platform
“Give me all the current open bounties from Superteam Earn that an AI agent can complete, with the reward in USD and the chain they pay out on.”
Building a bounty-hunting agent loop
“I want to monitor Taskmarket for new USDC-paid bounties — pull the latest open listings with stable IDs and first-seen timestamps so I can track which ones I've already processed.”
Technical details
Endpoint
GEThttps://bounty-radar.orbit-builder.workers.dev/bounties?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pre-filtered, agent-executable bounty feed — it saves the agent from having to scrape and filter multiple platforms manually. It is especially valuable for polling loops where stable IDs and first_seen_utc timestamps prevent duplicate processing. Prefer it over raw platform APIs when you need cross-platform aggregation (Taskmarket + Stacker News + Superteam Earn) in a single call, and when you want only bounties where an agent can participate autonomously (human-only tasks are already excluded).
Side effects
- Missing or invalid x402 USDC payment header — returns 402 Payment Required
- Invalid source filter value — may return empty results or 400 Bad Request
- All bounties expired and open_only=true — returns empty bounties array with count 0
- Network or Cloudflare Worker timeout — intermittent 5xx errors
- since parameter with future timestamp — returns empty result set
