This service is the API for querying blockchain data using GraphQL. It is part of StreamingFast.
See the different protocol-specific StreamingFast binaries at https://github.com/streamingfast/streamingfast#protocols
Current dgraphql implementations:
-
Using https://github.com/Gavinpub/ws (which supports subprotocol negotiation)
ws -s graphql-ws ws://127.0.0.1:8080/graphql
{"id":"3","type":"connection_init","payload":{"Authorization":"Bearer ......"},"variables":null}}
{"id":"3","type":"start","payload":{"query":"subscription{searchTransactionsForward(query: "status:executed", lowBlockNum:0, highBlockNum:0){ trace{ block { num } id }}}","variables":null}}
{"id":"3","type":"start","payload":{"query":"subscription{searchTransactionsForward(query: "status:executed", lowBlockNum:0, highBlockNum:0){ trace{ block { num } id }}}","variables":null}}
-
Using curl:
curl http://localhost:8080/graphql -XPOST -d '{"query": "{ searchTransactionsForward(limit: 10, query: "status:executed") { cursor } }"}' -H "Authorization: Bearer $SF_API_TOKEN" | jq .
curl http://localhost:8080/graphql -XPOST -d '{"query": "{ blockIDByTime(time: "2019-01-01T00:00:00Z") { time num } }"}' -H "Authorization: Bearer $SF_API_TOKEN" | jq .
