# API Integration Quickstart Prompt: generate typed TypeScript fetch code from docs.

Download the API Integration Quickstart JSON preset for Vezz me. Highlight any REST or GraphQL API documentation block to generate a production-ready TypeScript fetch/SDK snippet.

> **Best fit:** Best for full-stack and backend engineers integrating Stripe, OpenAI, GitHub, Twilio, or internal Swagger/OpenAPI endpoints.

## Live Webpage Walkthrough

- **Source:** API Reference — Create Message Endpoint (`docs.anthropic.com/en/api/messages`)
- **Recommended Context Mode:** Detailed

**Highlighted Passage:**
> POST /v1/messages. Headers: x-api-key (required), anthropic-version: 2023-06-01 (required), content-type: application/json. Body: model (string, required), max_tokens (integer, required), messages (array of {role, content}, required), metadata (optional), stop_sequences (optional), stream (optional), system (optional), temperature (optional).

**User Question (Shortcut):** "Generate a required-fields contract and a typed TypeScript fetch wrapper for this endpoint."

**Vezz me On-Screen Answer:**
1. **Required-Only Contract**:
   - `POST https://api.anthropic.com/v1/messages`
   - Headers: `x-api-key`, `anthropic-version: '2023-06-01'`, `content-type: 'application/json'`
   - Required Body: `model` (string), `max_tokens` (number), `messages` (`Array<{ role: 'user' | 'assistant'; content: string }>`)
2. **TypeScript Implementation**:
```ts
export async function createMessage(apiKey: string, body: { model: string; max_tokens: number; messages: Array<{ role: 'user' | 'assistant'; content: string }> }) {
  const res = await fetch('https://api.anthropic.com/v1/messages', {
    method: 'POST',
    headers: { 'x-api-key': apiKey, 'anthropic-version': '2023-06-01', 'content-type': 'application/json' },
    body: JSON.stringify(body),
  });
  if (!res.ok) throw new Error(`API ${res.status}: ${await res.text()}`);
  return res.json();
}
```

**Suggested Follow-Ups:**
- "Add exponential backoff on 429 and 529 status codes honoring the `retry-after` header."
- "Convert this function to Python 3.12 using `httpx` and `Pydantic`."

## Custom Prompt Preset for Vezz me

- **Preset Name:** API Integration Quickstart
- **Recommended Context Level:** Detailed
- **JSON Preset Download:** https://vezz.me/prompts/presets/api-integration-quickstart.json

```text
Turn the selected API documentation into a production-ready integration quickstart: 1) Required-Only Contract: list the HTTP method, path, auth header, and *only* the strictly required request parameters (ignore optional fields unless critical for safety like idempotency), 2) TypeScript Implementation: write a clean, dependency-free `async` TypeScript `fetch` function with explicit Request/Response interfaces and proper `!res.ok` error body handling, and 3) Production Gotchas: list pagination cursor rules, rate-limit headers (`429 Retry-After`), or webhook verification notes mentioned in the text.
```

**Why it works:** Filters out 40+ optional Swagger parameters so you see the exact minimum payload required for a `200 OK`, complete with TypeScript types and error handling.

## Step-by-step workflow

1. **Download and import the API Integration Quickstart JSON**: Save `api-integration-quickstart.json` and import it via the Vezz me extension popup.
2. **Highlight the endpoint parameter table and response example**: Select the REST or GraphQL endpoint docs on Stripe, GitHub, OpenAI, or any Swagger/Redoc page.
3. **Copy the generated TypeScript types and fetch wrapper**: Drop the generated interfaces and function directly into your codebase.

## From Swagger parameter wall to typed function in one shortcut

OpenAPI and Redoc reference pages often expand nested objects across three screenfuls of UI.

- Isolates the 3–5 strictly required fields from dozens of optional flags
- Generates copy-pasteable TypeScript `interface` definitions for both request payloads and response bodies
- Highlights rate-limit headers (`Retry-After`), pagination cursors, and idempotency headers

## Frequently asked questions

### Can I customize the preset to output Python (httpx/Pydantic) or Go structs instead of TypeScript?

Yes! After importing the preset into Vezz me, edit the word 'TypeScript' in the saved prompt to 'Python 3.12 with Pydantic v2 and httpx' or 'Go net/http with json struct tags'.

### Does it work on GraphQL schema docs too?

Yes. Highlight a GraphQL query/mutation definition and it will generate the query string, variables type, and response interface.

### Does it handle authentication headers?

Yes—Step 1 explicitly isolates required auth headers (`Authorization: Bearer`, `x-api-key`, HMAC headers) from the highlighted documentation.
