# Agent-Ready Recheck API

> Agent-Ready Recheck API is a paid API for AI agents from grokzilla.shop, paid per call via x402, $0.0102/call, status unknown (last checked 2026-10-29).

Re-runs a previous agent-readiness audit against a URL using its cached report ID and returns a diff of what changed since the last full audit.

## 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 agent-ready-recheck-api-afdf3b6d -d '<json body>'
```

Example prompt: Can you recheck my agent-ready audit score using report ID rpt_abc123xyz and show me what improved or regressed since last time?

## When to prefer this

Choose this endpoint when you already have a report_id from a recent agent-ready-audit (within 30 days) and want a fast, low-cost diff to measure progress without re-running the full audit. Prefer the full agent-ready-audit endpoint for first-time checks or when the prior report has expired.

## Known failure modes

- 400 Bad Request if report_id is missing, malformed, or older than 30 days — returned before payment is required
- 402 Payment Required if the request is sent without a valid x402 USDC payment on Base
- Report not found if the report_id never existed
- Stale data if the site changed significantly since the original audit was run

## How this service works

32 pay-per-call JSON APIs for AI agents. No account or API key: an unpaid POST returns HTTP 402, pay in USDC on Base with x402 v2, retry. Prices from $0.002 per call.

## Output

Returns a JSON object with the current agent-ready score (0-100) and letter grade, a diff object showing fixed and regressed checks versus the prior report, the score delta, subscores across dimensions (crawler_access, discoverability, structured_data, agent_interfaces, content_readability, machine_readable_summary), a count of still-failing checks, and a note reminding that this is a recheck only (not a full audit).
