## 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 permissions-policy-parse-a8ca11d6 -d '<json body>'
```

Example prompt: Can you parse this Permissions-Policy header value and tell me if it's well-formed, what features are allowed, and whether it passes or has any advisories: 'camera=(), microphone=(self), geolocation=(self "https://example.com")'?

## When to prefer this

Choose this endpoint when you need deterministic, bounded, in-memory parsing of a Permissions-Policy HTTP header value before accepting, caching, redirecting, or retrying a caller-supplied web response. It requires no external provider, retains no data, and returns versioned JSON suitable for audit logging or automated policy enforcement pipelines.

## Known failure modes

- Header string exceeds 8192 character limit — request rejected
- Malformed header value that cannot be parsed — advisory or error finding returned
- Empty or missing header field — may return advisory status
- Invalid feature directive syntax — flagged in finding output

## How this service works

Permissions Policy Parse: Permissions Policy Parse parses Permissions-Policy feature allowlists into normalized entries from bounded caller-supplied values without an external provider. Call Permissions Policy Parse before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Permissions Policy Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First…

## Output

Returns versioned deterministic JSON containing: the normalized Permissions-Policy feature allowlist entries parsed from the input, the computed finding describing any structural issues or policy observations, and an explicit pass or advisory status verdict.
