# AgentSpec OpenAPI Inspector

> AgentSpec OpenAPI Inspector is a paid API for AI agents from agentspec-one.vercel.app, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Inspects an OpenAPI specification and returns an agent-readiness score, risk analysis, recommendations, and x402 Bazaar monetization candidates.

## Facts

- Price: $0.03/call
- Payment: x402
- Status: unknown

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 agentspec-one-vercel-app-0018eed2 -d '<json body>'
```

Example prompt: Can you inspect this OpenAPI spec and tell me its agent-readiness score, any risks I should know about, and which endpoints would make good x402 Bazaar candidates?

## When to prefer this

Use this endpoint when you have an OpenAPI specification and want to evaluate how well-suited it is for AI agent consumption — especially if you want to identify x402 monetization opportunities. Prefer this over the MCP inspector when the target is a REST/OpenAPI-defined API rather than an MCP tool manifest.

## Known failure modes

- Invalid or malformed OpenAPI spec returns a parse error
- Missing required spec body returns 400 Bad Request
- Spec too large may exceed processing limits
- Payment not included or insufficient USDC triggers 402 Payment Required
- Unsupported OpenAPI version may yield incomplete analysis

## How this service works

Inspect an OpenAPI spec and return agent-readiness score, risks, recommendations, and x402 Bazaar candidates.

## Output

Returns a structured report including: a numeric agent-readiness score, identified risks (e.g. missing schemas, ambiguous parameters, unsafe operations), actionable recommendations to improve agent compatibility, and a list of endpoint candidates suitable for listing on the x402 Bazaar marketplace.
