Authentication

This API requires authentication via API key. Include your API key in the request header:

Required Header

X-API-Key: your_api_key_here

GraphQL AccessBETA

Most APIVerve APIs support GraphQL queries, allowing you to combine multiple API calls into a single request and retrieve only the data you need. This powerful feature enables you to orchestrate complex data fetching with precise field selection.

Not all APIs support GraphQL. Check the API schema or test in the GraphQL Explorer to confirm availability for this specific endpoint.

Token Cost: GraphQL requests cost 1 token for orchestration, plus the standard token cost for each API called in your query. For example, querying 3 APIs in a single GraphQL request would cost 1 + 3 = 4 tokens total.

GraphQL Endpoint

POST https://api.apiverve.com/v1/graphql

GraphQL Query Example

query {
  citieslookup(
    input: { city: "San Francisco" }
  ) {
    search
    foundCities
  }
}

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

Try in GraphQL Explorer GraphQL Documentation
