## 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-accessibility-evidence-collector-9b00a017 -d '<json body>'
```

Example prompt: Can you gather accessibility compliance evidence for https://example.com/about — I need to know what a11y issues exist on that page so I can document them for our audit report?

## When to prefer this

Use this endpoint when you need to programmatically collect accessibility compliance evidence for a specific public URL, especially in automated auditing pipelines, legal documentation workflows, or CI/CD accessibility gating — and when pay-per-call USDC micropayment pricing (x402 on Base) is acceptable for your use case.

## Known failure modes

- Invalid or non-public URL returns an error response
- URL behind authentication or firewall cannot be fetched
- Malformed request body (missing required fields) causes 400-level error
- Payment not settled in USDC on Base causes 402 Payment Required response
- Timeout if the target page is slow or unresponsive

## 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

Returns a JSON object with ok: true, the capability identifier 'mg-a11y-evidence', and a data object containing the extracted accessibility evidence findings for the submitted URL.
