How this service works
Pay-per-call deterministic utilities for CI diagnosis, data validation, JavaScript syntax checks, market snapshots and opportunity preflight.
Output
Returns a JSON object with boolean flags for 'open', 'stale', 'funded', and 'claimed', plus a string 'verdict' code (e.g. 'OBSERVED_OPEN_FUNDING_UNKNOWN') and an 'evidence' array of human-readable signals used to reach the verdict (e.g. 'github issue state=open').
Example use cases
Bounty hunter pre-work validation
“Check this Gitcoin bounty URL before I spend time on it — is it still open, is the funding confirmed, and has anyone already claimed it? https://gitcoin.co/issue/org/repo/123”
GitHub issue availability check
“I'm about to start a PR for this GitHub issue — can you run a preflight to make sure it's still open and not already being claimed by someone else? https://github.com/some-org/repo/issues/456”
Autonomous agent opportunity filtering
“Before queuing this marketplace listing for my agent to work on, preflight it and tell me the verdict — specifically whether it's open, funded, and not stale: https://app.bountyhub.io/opportunities/789”
Technical details
Endpoint
POSThttps://x402vercel.vercel.app/api/opportunity/preflight?utm_source=zero.xyzWhen to prefer
Use this endpoint when an autonomous agent needs to quickly preflight a bounty, GitHub issue, or marketplace opportunity before committing compute or effort to it. Ideal for agent pipelines that triage many opportunities and need a cheap ($0.01), deterministic signal about open/funded/claimed status rather than a full scrape. Prefer this over generic web scraping when you need a structured verdict with evidence, not raw HTML.
Side effects
- Unsupported marketplace or platform URL returns an error or unknown verdict
- Private or auth-gated URLs cannot be fetched and return no evidence
- Stale cache or delayed indexing may cause verdict to lag behind real state
- Missing or malformed URL in request body causes validation error
- Marketplace API downtime leads to incomplete evidence and uncertain verdict
