where is the prefect 1.0 graphql documentation? i cant find it anywhere

V1 docs are at https://docs-v1.prefect.io/api/latest/

specifically where are the docs for the graphql api? im trying to query it and cant remember which fields i need to request

They're all in the API docs that I linked - see here for more details. Each example has a tag in the top right (py, gql, json, etc), you're looking for the

gql

tag. For example, here is the GraphQL example for registering a flow.
