# MilliAPI AI Web Readiness Audit

> MilliAPI AI Web Readiness Audit is a paid API for AI agents from milliapi.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Audits a public HTTPS page for AI-agent and answer-engine readiness, returning robots.txt, llms.txt, meta tags, Open Graph, JSON-LD, and a 0-100 readiness score.

## Facts

- Endpoint: GET https://milliapi.com/api/agent-web-audit
- Price: $0.005/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 milliapi-ai-web-readiness-audit-de41eb06
```

Example prompt: Can you run an AI web readiness audit on https://myblog.com/about and tell me the score, whether GPTBot is allowed, and what the top recommendations are to improve my page's discoverability?

## When to prefer this

Use this endpoint when you need a single-call, comprehensive AI-readiness snapshot of a public web page — covering robots.txt, llms.txt, canonical tags, Open Graph, JSON-LD, AI crawler access, and actionable repair artifacts — without having to call separate metadata, robots, and llms.txt endpoints individually. Prefer it over individual metadata or robots.txt checks when you want a bundled score plus fix recommendations in one request.

## Known failure modes

- Private IP or localhost URL rejected with 4xx error
- Non-HTTPS URL rejected
- Non-standard port in URL rejected
- Target page returns 5xx — audit may be incomplete or return partial data
- URL format invalid — returns validation error
- Rate limit exceeded — returns 429
- Target page unreachable — network timeout returns error response

## How this service works

Tiny machine-readable APIs that AI agents can discover, pay for with x402 USDC on Base, and use instantly. Services start at $0.001 per call.

## Output

A JSON object containing: a 0–100 readiness score, a verdict enum (ready/mostly_ready/needs_work/blocked), a summary string, an agentRecommendation, an array of prioritized recommendations with repair artifacts, page metadata (title, H1 count, canonical, Open Graph, JSON-LD block count, noindex flag), robots.txt and llms.txt status (HTTP status + presence), per-crawler AI access map (e.g. GPTBot allowed/blocked), a baseline token for future change detection, cache metadata, and the list of checks bundled in the call.
