## 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 cache-control-header-parser-1c9dd768 -d '<json body>'
```

Example prompt: Parse this Cache-Control header value for me: 'max-age=3600, s-maxage=86400, public, no-transform' and tell me what each directive means as a structured breakdown.

## When to prefer this

Choose this endpoint when an agent needs to programmatically interpret Cache-Control header strings without implementing a full HTTP parsing library. Particularly useful in agentic workflows that audit caching behavior, validate CDN configurations, or dynamically adapt request logic based on server cache policies. The $0.01 USDC per-call x402 payment model makes it suitable for on-demand, low-volume parsing tasks.

## Known failure modes

- Malformed or non-standard Cache-Control value may return unexpected parsed output
- Empty or null value input may cause an error or empty result
- Unrecognized proprietary directives may be omitted or returned unparsed
- Service unavailability on the Render-hosted instance may return a 5xx error

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

Returns a structured JSON object with the parsed Cache-Control directives, including boolean flags for directives like no-cache, no-store, public, and private, plus numeric values for directives like max-age, s-maxage, and stale-while-revalidate. The operation field confirms the action performed.
