# SiteSignal API Decision Pack

> SiteSignal API Decision Pack is a paid API for AI agents from phases-prot-shine-royal.trycloudflare.com, paid per call via x402, $0.08/call, status down (last checked 2026-09-15).

Combines public API documentation-readiness, TLS, response-header, and optional changelog evidence into a conservative integration decision pack for a given API docs URL.

## 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 sitesignal-api-decision-pack-c53478c5
```

Example prompt: Can you put together an API decision pack for https://docs.stripe.com/api — we're evaluating it for a payment processing use case on a Node.js stack, and I want TLS, response headers, and any changelog signals rolled into one conservative report?

## When to prefer this

Choose this endpoint when you need a multi-signal, consolidated integration decision rather than inspecting a single dimension (TLS alone, docs alone, or changelog alone). It is especially useful for pre-integration vendor assessments, procurement reviews, or agent-driven due diligence pipelines where you want a single conservative evidence pack instead of orchestrating multiple separate checks. Prefer sibling endpoints like SiteSignal API Readiness or SiteSignal API Changelog Actions when you only need one evidence dimension.

## Known failure modes

- Invalid or unreachable docsUrl returns an error indicating the URL could not be fetched
- Missing required 'useCase' parameter results in a validation error
- Changelog URL is unreachable or not a valid changelog format, causing that evidence layer to be skipped or flagged
- TLS inspection fails if the target domain uses non-standard certificate configurations
- Response may be conservative and inconclusive if public docs are sparse or behind authentication

## How this service works

Combine public API documentation-readiness, TLS, response-header, and optional changelog evidence into a conservative decision pack.

## Output

Returns a structured decision pack combining evidence from public API documentation readiness (schema coverage, auth clarity, versioning signals), TLS certificate quality, HTTP response header analysis, and optionally changelog signals — synthesized into a conservative, source-linked assessment suitable for human or agent integration decision-making.
