# apiacre.com OpenAPI Test Generator

> apiacre.com OpenAPI Test Generator is a paid API for AI agents from apiacre.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-16).

Generates deterministic, syntax-validated pytest and requests smoke tests from a caller-supplied OpenAPI 3 document, with mutating operations disabled by default.

## Facts

- Endpoint: POST https://apiacre.com/v1/developer/openapi-test-generate
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-16
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/apiacre-com-openapi-test-generator-21213d3b
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_zThieZpnBI9-XZkgk4wbE

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 apiacre-com-openapi-test-generator-21213d3b -d '<json body>'
```

Example prompt: Take this OpenAPI 3 spec and generate a deterministic pytest and requests smoke test file from it — keep all mutating operations (POST, PUT, DELETE) disabled by default.

## When to prefer this

Choose this endpoint when you need to quickly scaffold a deterministic, ready-to-run pytest smoke test file directly from an OpenAPI 3 specification without writing tests manually. It is especially useful for CI/CD integration, contract validation, and onboarding to third-party APIs where a spec is available but no test suite exists.

## Known failure modes

- Invalid or malformed OpenAPI 3 document returns a validation error
- Non-OpenAPI 2/3 documents (e.g. plain JSON schemas) may be rejected
- Very large specs may exceed payload limits
- Missing required fields in the OpenAPI document may cause partial test generation
- Network timeout if the spec document is excessively large

## How this service works

Generate deterministic, syntax-validated pytest and requests smoke tests from a caller-supplied OpenAPI 3 document, with mutating operations disabled by default.

## Output

Returns a pytest-compatible test file with syntax-validated smoke tests covering the endpoints defined in the supplied OpenAPI 3 document. Mutating operations (e.g. POST, PUT, DELETE) are disabled by default. Tests use the requests library and are deterministically generated from the spec structure.
