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 a bounded inventory of observed key paths and their inferred types from the JSON API response, along with the HTTP status code and a SHA-256 hash of the response body as evidence. No raw field values are included — only structural shape metadata.
Example use cases
Example prompt
“Can you inspect the JSON structure of https://api.example.com/v1/products — show me the key paths and value types (up to depth 3 and 40 paths) without revealing any actual data values?”
Technical details
Endpoint
GEThttps://holder-victor-nova-mag.trycloudflare.com/x402/json-api-shapeWhen to prefer
Use this endpoint when you need to discover or document the structural shape of a public JSON API without exposing sensitive raw values. It is ideal for API integration planning, schema discovery, or structural auditing where privacy or data minimization matters. Prefer this over full response capture endpoints when you only need the key/type inventory and want SHA-256 evidence of the response without storing actual data.
Side effects
- URL is not publicly accessible or requires authentication — returns error indicating unauthenticated access failed
- URL does not return valid JSON — shape cannot be parsed
- maxDepth or maxPaths limits exceeded — result is truncated to configured bounds
- Target server times out or returns non-200 status — error with status code returned
- URL is malformed or not a valid URI — schema validation error
