The Graph

Discover subgraphs, run GraphQL, read Token API and Market data.

Use THEGRAPH_API_KEY for gateway GraphQL and Token API. Use SUBSTREAMS_API_KEY only for the Substreams data plane. Market reads need a stored Portal bearer.

Discovery never introspects schema unless you run Get schema. Query outputs include query_url and query_url_x402. Never auto-pay Graph x402 from a step.

Group	Actions
Discovery	Search, recommend, detail, schema, find by contract
Query	Query subgraph, indexing status, lending snapshot
Token API	Balances, transfers, holders, DEX swaps, NFT activity
Substreams	Search packages, get package, default endpoint
Market	Subscription, usage, bill, connections, hosted deployments
