Agent & automation tools

Check JSON against a structural schema.

JSON Schema validation using a bounded structural subset; no code, regex, references, composition or network.

Try your data — no sign-up API access & schema Try the fixed example

Try with your own data

Runs in this browser. No account, wallet or API key. Your input and result are not sent to InvokePort. API automation uses a scoped key.

Arguments: schema and value

Calculated by the same tool engine on this fixed synthetic example. No account, payment or external provider call. Use the tool page to submit your own input.

What you receive

Explicit valid / invalid result
Named bounded schema subset
Identical browser and API validation logic

Scope & limits

Bounded structural subset only. No refs, regex, formats or composition; unsupported schemas are rejected.
Not a full JSON Schema implementation or a security certification.

Use it in your workflow

Supply a schema and value in the input object.
Run the check locally.
Use a scoped key for repeated agent calls.

API schemas and request examples are on the tool reference. Read the authentication and payment guide.

Your data & delivery

Submitted input and result bodies are not stored by InvokePort. Operational metadata and hashes may be recorded. Do not submit credentials or unnecessary personal data.

Free results are not retained for recovery. Save the returned JSON; do not automatically repeat a request with an unknown outcome.
