Short answer

How do I verify partner API specs with my AI?

Your AI uses the validate_openapi tool to scan raw OpenAPI files for syntax errors, missing required fields, or broken references. You get a clean report of every structural issue found in the spec. This prevents integration failures before you start coding.

Where the errors land.

The audit outcomes.

The AI processes the spec and organizes the findings into these categories.

SYNTAX

Broken structure

The AI identifies malformed YAML or JSON that prevents the file from being parsed. You get the exact line numbers where the syntax fails.

SCHEMA

Invalid definitions

The AI catches missing required properties or incorrect data types. This ensures the spec actually follows the OpenAPI standard.

LOGIC

Broken references

The AI finds dead links and unresolved $ref pointers. You'll know exactly which components are missing from the definition.

HUMAN

Manual review needed

The AI flags ambiguous descriptions or logical inconsistencies. You decide if these nuances matter for your specific implementation.

The workflow

What your AI does when a spec arrives.

The AI acts as a gatekeeper, ensuring the documentation is actually usable.

  1. Ingest the file

    Your AI reads the raw OpenAPI content you provide, whether it's a local file or a URL.

    validate_openapi

  2. Run structural audit

    The AI checks the file against the official OpenAPI specification rules.

    validate_openapi

  3. Identify broken links

    The agent hunts for internal references that point to non-existent objects.

    validate_openapi

  4. Report discrepancies

    The AI summarizes all errors and warnings into a readable list for you.

    validate_openapi

  • Validate this OpenAPI spec for me: https://api.partner.com/v3/openapi.json

  • Check the local file ./specs/auth-api.yaml for any broken $ref pointers.

  • Run a validation on this spec and tell me if any required fields are missing in the user object.

  • Scan this API definition and list all syntax errors found in the paths section.

FAQ

How this task behaves.

  • 01

    Can the AI fix the errors in the spec automatically?

    No. The AI identifies and reports the errors, but you must manually edit the file to fix them.

  • 02

    Does the AI check if the API actually works?

    No. This tool only validates the structure and syntax of the definition file, not the live endpoint's behavior.

  • 03

    Can I validate specs hosted on private URLs?

    Yes, as long as your AI client has the network access required to reach that URL.

  • 04

    Will the AI delete my original files?

    No. The AI only reads the content to perform the validation; it has no permission to modify or delete your local files.

  • 05

    Does it support both JSON and YAML formats?

    Yes, the validation works for both standard OpenAPI formats.
