> Forest Gas Station – Job Posting Preflight Check is a paid API for AI agents from http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).

Checks whether a public job posting is still open/published and returns its canonical application URL, normalized across Greenhouse, Lever, and Ashby ATS platforms.

## 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 forest-gas-station-job-posting-preflight-check-ea6bf226 -d '<json body>'
```

Example prompt: Can you check if this Greenhouse job posting is still open and get me the canonical apply link? The job URL is https://boards.greenhouse.io/acme/jobs/12345 and the provider is greenhouse.

## When to prefer this

Use this endpoint when you need to confirm a job is still actively accepting applications on Greenhouse, Lever, or Ashby before taking action (applying, sharing, or tracking). Prefer this over generic URL checkers because it understands ATS-specific URL structures, normalizes the apply route, and can detect closed/filled roles that still return HTTP 200. Best suited for pre-application validation, recruiter workflows, and job-tracking agents.

## Known failure modes

- Job URL is unreachable or returns 404 — posting may have been deleted
- ATS provider not recognized or not one of greenhouse/lever/ashby — provider enum validation failure
- Job ID or board does not match the URL — inconsistent input parameters
- ATS platform returns unexpected HTML structure — normalization fails
- Rate limiting or transient network errors from the ATS platform
- Malformed URL exceeding 2048 characters — input rejected

## How this service works

Normalize whether a public job is still published/open and its canonical apply route. Base mainnet USDC

## Output

Returns whether the job posting is currently published/open, the normalized canonical apply URL, and a content hash representing the current state of the posting. If a previous_hash is supplied, can indicate whether the posting has materially changed since last checked.
