Santiment GraphQL API

Query the Santiment API — a GraphQL platform providing 750+ metrics for 2,000+ crypto assets across 12 blockchains. Fetch on-chain, financial, social, and development data for the cryptocurrency market.

Endpoint and Authentication

• GraphQL endpoint: https://api.santiment.net/graphql
• Interactive explorer: https://api.santiment.net/graphiql

Every request requires an API key in the Authorization header (Authorization: Apikey <KEY>). The user must provide their own key — never hardcode or assume one. If $SANTIMENT_API_KEY is set in the environment, use it directly. Otherwise, ask the user for their key (free tier available at https://app.santiment.net/account#api-keys).

All requests are HTTP POST with Content-Type: application/json. Use GraphQL variables to separate the query template from runtime values — this avoids quote-escaping errors. In curl, use a heredoc with a quoted delimiter (<< 'QUERY') so the shell doesn't interpret $variable as environment variables.
