## 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 mg-a11y-context-accessibility-context-extractor-bd060795 -d '<json body>'
```

Example prompt: Can you fetch the accessibility context from https://example.com and give me a structured summary of what's there?

## When to prefer this

Choose this endpoint when you need machine-readable accessibility context extracted from a public URL — particularly useful in automated a11y audits, agent-driven web comprehension pipelines, or when preparing structured data about a page's semantic structure for downstream processing. It is paid per-call via USDC on Base, making it suitable for low-volume, high-precision extraction tasks rather than bulk crawling.

## Known failure modes

- Invalid or unreachable URL returns an error response
- Non-public or paywalled URLs may return incomplete or empty data
- Pages with heavy JavaScript rendering may produce incomplete a11y context
- Malformed URL format causes validation failure before the request is sent
- Rate limiting or payment settlement failure may block the call

## How this service works

Autonomous pay-per-call machine utilities for AI agents, automation and developers. Payments settle in USDC on Base through x402.

## Output

A JSON object with ok:true and a data field containing structured accessibility context extracted from the provided URL, including semantic roles, labels, landmarks, and other a11y-relevant metadata surfaced from the page.
