# Sample API Response Generator

> Generate realistic REST, JSON:API, GraphQL and error-envelope responses with pagination.

A sample API response generator builds realistic JSON payloads in the shapes real APIs use: a paginated REST collection, a single resource, a success envelope, JSON:API, a GraphQL data response, cursor pagination, an error object, or RFC 9457 problem details — complete with links, meta blocks and request identifiers.

## Key facts

- **Response styles:** Eight — REST collection and single, success envelope, JSON:API, GraphQL, cursor pagination, error object and RFC 9457 problem details
- **Pagination:** Page numbers, totals, page counts and next/previous links are all computed consistently
- **Privacy:** Runs entirely in your browser — nothing is uploaded
- **Cost:** Free, unlimited, no sign-up

## How to use

1. Choose the response style.
2. Choose the resource.
3. Set the items in this page.
4. Set the current page.
5. Set the page size.
6. Set the total records.
7. Choose the http status.
8. Turn "Include links and meta" on or off as needed.
9. Turn "Pretty-print" on or off as needed.
10. Enter or paste your seed.
11. The result appears immediately — copy or download it.

## FAQ

### What is RFC 9457?

The successor to RFC 7807, it standardises a machine-readable error body with type, title, status, detail and instance members, served as application/problem+json. Using it means clients can handle your errors without bespoke parsing.

### Why does the generator compute page links?

Because off-by-one errors in pagination links are one of the most common API bugs. Generating consistent next, previous, first and last links gives you a correct reference to test your own implementation against.
