How this service works
Pay-per-call utilities for AI agents. Payments in USDC on Base via x402 v2; no accounts or API keys. Failed requests are never charged. No endpoint performs server-side fetching of caller-supplied URLs.
Output
Returns a JSON object with a human-readable grade (e.g. 'partially agent-ready'), a numeric readiness score (0–100), and an array of individual checks that contributed to the assessment.
Example use cases
Audit a site before agent crawling
“Before I let my AI agent scrape this site, can you assess its agent-readiness? I have the HTML, response headers, and robots.txt — tell me the grade and score so I know if it's safe to proceed.”
Verify llms.txt compliance for a new tool
“I've just set up llms.txt on my site. Can you run an agent-scan on the HTML and llms.txt I've pasted to see if my site is grading as fully agent-ready yet?”
Compare agent-readiness across competitor pages
“Here are the HTML and robots.txt for three competitor landing pages — can you score each one for AI agent accessibility and tell me which grades as most agent-friendly?”
Technical details
Endpoint
POSThttps://agent-tools-x402.t6y11a.workers.dev/api/agent-scan?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, scored assessment of a webpage's AI-agent accessibility — especially when you already have the page's HTML, headers, robots.txt, or llms.txt locally and want a cheap ($0.01), keyless, pay-per-call evaluation without setting up an account. Prefer it over manual inspection when building agent pipelines that need to programmatically decide whether to crawl or interact with a site.
Side effects
- Missing or malformed HTML input may result in low-quality or incomplete scoring
- If none of the optional fields (headers, llms.txt, robotsTxt) are supplied, checks relying on those signals will be skipped, potentially lowering the score
- Payment failure via x402 results in no charge and no response
- Overly large HTML payloads may be rejected or cause timeouts
