The Finstock API is based on GraphQL API. GraphQL is a query language which offers much more flexibility for integrations. It allows you to request the exact data you need, cutting down the number of calls you must perform to get it. The availability of all data at one endpoint is also the biggest advantage of GraphQL over the REST API (which has an endpoint for each resource object).

The Finstock GraphQL API provides one endpoint to request credit scores, default probabilities & fundable amounts, in an efficient and flexible manner.
