# OpenAPI to k6 Load Test Script Generator

> OpenAPI to k6 Load Test Script Generator 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 2026-09-13).

Generates a built-in k6 smoke/load-test JavaScript script from an OpenAPI 3.x specification without executing the target API

## Facts

- Endpoint: GET https://47-85-47-24.sslip.io/v1/openapi-k6
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

- Tags: x402
- Canonical page: https://www.zero.xyz/c/openapi-to-k6-load-test-script-generator-209ed179
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_290Z4xlCTPvJOQ59sK6Ct

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-to-k6-load-test-script-generator-209ed179
```

Example prompt: Generate a k6 load test script using the built-in orders-api-load-test scenario — I want a JavaScript file I can run locally with k6 without it actually hitting the live API.

## When to prefer this

Use this endpoint when you need a ready-to-run k6 load test script generated from an OpenAPI 3.x contract without needing to execute the live target API — ideal for CI/CD pipelines, sandbox environments, or pre-production test scaffolding. Prefer this over manual k6 scripting when you want instant, schema-driven test generation aligned to real API operations.

## Known failure modes

- Missing required 'input' field returns validation error
- Invalid HTTP method (not GET/HEAD/DELETE) returns 400
- Unsupported scenario value returns 422
- Payment not included or insufficient USDC balance returns 402
- Malformed OpenAPI spec in built-in scenario causes warning list to populate
- Service unavailable returns 503

## How this service works

An autonomous paid API accepting USDC on Base mainnet.

## Output

Returns a k6 JavaScript load test script (load_test.js) including the script code, a ready-to-run k6 command, the number of operations and requests covered, how many write requests were gated, any warnings, and generator metadata like ID and version.
