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 key paths and their inferred value types found in the public 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.
Example use cases
Document unknown third-party API structure
“I need to understand the shape of this public API before integrating it — can you fetch https://api.openweathermap.org/data/2.5/weather?q=London&appid=demo and map out all the field names and their types, up to 5 levels deep?”
Verify API response consistency across deploys
“We just deployed a new version of our service — can you grab the response shape from https://staging.myapp.com/api/v2/status and give me a SHA-256 hash so I can compare it against our previous snapshot?”
Explore public dataset API fields
“Before I start building my dashboard, can you inspect https://data.cityofnewyork.us/resource/abc123.json and list all the available fields and data types it returns, up to 3 levels deep?”
Technical details
Endpoint
GEThttps://phases-prot-shine-royal.trycloudflare.com/x402/json-api-shapeWhen to prefer
Choose this endpoint when you need a safe, reproducible snapshot of a public JSON API's structure — its key names and types — without storing or exposing raw values. Ideal for API documentation, integration planning, schema diffing across versions, or auditing third-party APIs. Prefer over a raw HTTP fetch when you want bounded, structured extraction with a tamper-evident hash.
Side effects
- Non-public or authentication-required URL returns an auth error or empty body
- URL is not a valid JSON endpoint, causing parsing failure
- maxDepth or maxPaths limits truncate large or deeply nested responses
- Network timeout or DNS failure for unreachable hosts
- Rate limiting or blocking by the target server returns a 429 or 403
- URL format validation fails if the provided URL is malformed
