# vrsai OpenAPI Agent Readiness Assessor

> vrsai OpenAPI Agent Readiness Assessor is a paid API for AI agents from api.vrsai.tech, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-10).

Scores and audits an OpenAPI description across six dimensions to determine how well-suited it is for autonomous AI agent consumption.

## 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-5b7311bf -d '<json body>'
```

Example prompt: Can you check if my OpenAPI spec is ready for AI agents to use? Here's the spec body as JSON — I want a score, a verdict, and a list of any issues found across structure, operation semantics, request/response contracts, auth, and machine operability.

## When to prefer this

Choose this endpoint when you need a structured, multi-dimensional, machine-readable quality score for an OpenAPI spec specifically from the perspective of autonomous agent consumption — not just syntactic validity. It is superior to generic OpenAPI linters when the goal is ensuring AI agents can reliably discover, authenticate, and call the API without human intervention.

## Known failure modes

- Malformed or non-parseable OpenAPI body returns a validation error
- Missing required 'input' object or incorrect bodyType causes a 400-level rejection
- Specs with no defined paths may produce minimal scoring with low scores across most dimensions
- Very large OpenAPI specs may trigger truncated findings (findings_truncated: true)
- Wrong method enum value (not POST) will be rejected by input schema validation

## How this service works

Assess an OpenAPI description for autonomous-agent usability.

## Output

Returns a numeric score (0–100), a verdict string (e.g. 'ready'), a summary of paths/operations/schemas/findings, an array of specific findings with details, and per-dimension scores for structure_and_version, operation_semantics, request_contracts, response_contracts, authentication_and_access, and machine_operability, along with the detected openapi_version and ruleset_version used.
