# LineageLint OpenAPI TypeScript SDK Generator

> LineageLint OpenAPI TypeScript SDK 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 TypeScript Fetch SDK from an OpenAPI spec using the built-in orders-api scenario, returning client source files, types, and operation wrappers.

## Facts

- Endpoint: GET https://47-85-47-24.sslip.io/v1/openapi-typescript-sdk
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/lineagelint-openapi-typescript-sdk-generator-2dbe4ef6
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_me1lFHdj99_txJVo467J8

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 lineagelint-openapi-typescript-sdk-generator-2dbe4ef6
```

Example prompt: Use LineageLint to generate a TypeScript Fetch SDK for the orders API scenario — I want the full client source files including the OrdersClient class, type declarations, package.json, and tsconfig.

## When to prefer this

Choose this endpoint when you need to auto-generate a TypeScript Fetch SDK from an OpenAPI specification, specifically for the orders-api scenario, and want a complete scaffolded project (client class, typed operations, package.json, tsconfig) rather than manual client code. Prefer this over generic code generation services when you need strongly-typed TypeScript fetch wrappers with operation metadata and warnings in a single paid API call.

## Known failure modes

- Invalid or missing 'scenario' query parameter returns an error — only 'orders-api-typescript-sdk' is supported
- Unsupported HTTP method (e.g. POST or PUT) returns 405 Method Not Allowed
- Payment not included or insufficient USDC results in 402 Payment Required
- Malformed input schema or missing required 'type' and 'method' fields returns 400 Bad Request
- Network or server error on the sslip.io host returns 500 or connection timeout

## How this service works

An autonomous paid API accepting USDC on Base mainnet.

## Output

Returns a JSON object containing generated TypeScript SDK files (src/client.ts, package.json, tsconfig.json, README.md), metadata about the generator (generator_id, generator_version, format: typescript-fetch-sdk), a list of operations with typed inputs and responses, operation and type declaration counts, a sha256 of the source spec, and any warnings about the generated code.
