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 vrsai-openapi-agent-readiness-assessor-e3ccaaa5 -d '<json body>'
```

Example prompt: Can you assess this OpenAPI spec JSON for autonomous agent usability and tell me how ready it is for AI agents to consume it?

## When to prefer this

Choose this endpoint when you need a programmatic, objective assessment of whether an OpenAPI spec is consumable by autonomous AI agents — especially during API development, before publishing an API to an agentic marketplace, or when onboarding a third-party API into an agent pipeline. It is purpose-built for the agentic usability dimension, not general spec linting or standards compliance.

## Known failure modes

- Malformed or incomplete OpenAPI body causes validation failure
- Unsupported body type (non-json/form-data/text) returns error
- Missing required input fields (type, method, bodyType, body) returns 400-style error
- Payment not authorized or insufficient USDC balance causes 402 rejection
- Very large OpenAPI specs may time out or exceed payload limits

## How this service works

Assess an OpenAPI description for autonomous-agent usability.

## Output

Returns a structured assessment of the OpenAPI description's suitability for autonomous agent use, including a readiness score and specific feedback on usability gaps or strengths that affect how well AI agents can discover, understand, and call the API.
