## 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 nakonets-opportunity-preflight-check-f570fd57 -d '<json body>'
```

Example prompt: Before I start working on it, can you preflight check this GitHub issue to see if it's still open, not stale, and whether the bounty funding is confirmed? https://github.com/some-org/some-repo/issues/123

## When to prefer this

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.

## Known failure modes

- 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

## 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').
