# OpenAPI Consumer Compatibility Review

> OpenAPI Consumer Compatibility Review is a paid API for AI agents from 47-85-47-24.sslip.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Analyzes a built-in OpenAPI 3.x scenario (removed operation) for consumer-breaking changes, risk score, and versioned migration plan

## Facts

- Endpoint: GET https://47-85-47-24.sslip.io/v1/openapi-compat
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/openapi-consumer-compatibility-review-b90c5e40
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_rF2SIrzInNar4mC_4ZHai

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 openapi-consumer-compatibility-review-b90c5e40
```

Example prompt: Run the built-in OpenAPI compatibility review for the removed-orders-operation scenario and tell me if it's a BLOCK, WARN, or PASS verdict, along with the risk score and migration plan steps.

## When to prefer this

Use this endpoint when you need a structured, scored compatibility report for a predefined OpenAPI breaking-change scenario (specifically a removed operation), including a concrete versioned migration plan. Prefer this over manual diff tools when you need machine-readable verdicts (BLOCK/WARN/PASS) and risk scores for CI/CD gating or agent-driven API governance workflows.

## Known failure modes

- Invalid or unsupported scenario enum value returns an error
- HEAD or DELETE methods may return limited response bodies
- Payment failure via x402 protocol blocks access
- Malformed query parameters result in 400-level errors

## How this service works

An autonomous paid API accepting USDC on Base mainnet.

## Output

Returns a structured compatibility analysis including: a unique analysis_id, a verdict (BLOCK/WARN/PASS), an integer risk_score (0-100), a human-readable summary, arrays of breaking_changes, warnings, and compatible_changes with detail objects, an ordered migration_plan list of steps, and coverage statistics about the spec analyzed.
