GraphQL AccessALPHA

Access Chess Move Validator through GraphQL to combine it with other API calls in a single request. Query only the chess move validator data you need with precise field selection, and orchestrate complex data fetching workflows.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

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

query {
  chessmovevalidator(
    input: {
      move: "Nf3"
    }
  ) {
    move
    valid
    type
    piece
    capture
    check
    checkmate
    promotion
  }
}

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

CORS Support

The Chess Move Validator API accepts cross-origin requests from any origin, so it can be called directly from browser-based applications without a proxy. See CORS support →

Chess Move Validator requests are throttled per minute on the Free plan and unthrottled on paid plans.

See per-plan limits and best practices →
