# SiteSignal Public JSON API Response Shape Snapshot

> SiteSignal Public JSON API Response Shape Snapshot is a paid API for AI agents from obtain-incentive-exceptions-speakers.trycloudflare.com, paid per call via x402, $0.05/call, status down (last checked 2026-09-16).

Inventories key paths and value types from a public JSON API response, returning structural shape metadata with SHA-256 evidence but no raw values.

## Facts

- Endpoint: GET https://obtain-incentive-exceptions-speakers.trycloudflare.com/x402/json-api-shape
- Price: $0.05/call
- Payment: x402
- Status: down
- Last checked: 2026-09-16

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-public-json-api-response-shape-snapshot-220cfb56
```

Example prompt: Snapshot the shape of this public JSON API — https://api.example.com/v1/products — show me all the key paths and their types up to depth 4, but don't include any actual values.

## When to prefer this

Use this endpoint when you need to understand the structural shape of a public JSON API response without exposing sensitive raw values. Ideal for integration planning, API documentation, schema validation, or auditing third-party JSON endpoints. Prefer this over raw fetch tools when privacy or data minimization is important, or when you only need the type structure rather than actual data.

## Known failure modes

- Target URL is not a valid public JSON endpoint — returns an error indicating non-JSON content type
- Target URL requires authentication — returns a shape with minimal or no keys
- Request depth or path count exceeds maximum limits (depth > 6, paths > 100) — returns validation error
- Target URL is unreachable or returns non-2xx status — returns status code with empty or partial shape
- URL format is invalid — schema validation error on input

## How this service works

Inventory bounded observed key and type paths from one unauthenticated public JSON API response, with status and SHA-256 evidence but no raw values.

## Output

Returns an inventory of observed key paths and their inferred types from the JSON API response, along with HTTP status code and a SHA-256 hash of the response body as evidence. No raw field values are exposed. The shape is bounded by configurable depth and path count limits.
