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.
Example use cases
Pre-cache web response header audit
“Before I cache this web response, parse and normalize its Permissions-Policy header — 'camera=(), fullscreen=(self), payment=("https://pay.example.com")' — and tell me if it passes or has any issues.”
Security scan of third-party API response
“I just got a response from a third-party API and want to check the Permissions-Policy header before I redirect users to it. Can you parse 'geolocation=(), usb=(self), microphone=()' and give me the normalized entries and a pass or advisory verdict?”
Pre-acceptance check on incoming web header
“Before my agent accepts this caller-supplied web response, analyze the Permissions-Policy header value 'accelerometer=(), gyroscope=(self), camera=(self "https://trusted.com")' and return the normalized allowlists and finding.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/permissions-policy-parseWhen to prefer
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.
Side effects
- 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
