}Resolver boilerplate
Writing mock resolvers by hand is slow and easy to get wrong.
“String” everywhere
Default mocks return meaningless placeholder values.
Local-only tooling
In-process mocks do not help designers, QA or mobile teams.
What you get
Schema-first
Define types and operations; MockAPI resolves them with generated data.
Realistic nested data
Fields map to 140+ data types so lists and relations look real.
Queries and mutations
Realistic responses for the queries and mutations your client sends, including named operations and aliases.
GraphiQL playground
Explore and test your schema in the browser.
Models shared with REST
Reuse the same models across REST and GraphQL endpoints.
AI-agent ready
Agents can create GraphQL endpoints through the MCP server.
Get started in three steps

Create a schema
Write SDL or build types from your existing models.
- 02
Add operations
Define the queries and mutations your client needs.
- 03
Query the endpoint
POST queries to https://graphql.mockapi.com with your API key.
FAQ
Common questions
Which GraphQL clients work?
Any spec-compliant client: Apollo Client, urql, Relay, graphql-request or plain fetch.
Can I mock REST and GraphQL in one project?
Yes. Models are shared, so both protocols return the same fields. GraphQL responses are generated on each request and do not read stateful records.
Build against a mock API that behaves like your real one
Create your first endpoint in under two minutes.
