…tly, pay-per-query over x402) Adds a `thegraph` action provider that lets an agent query The Graph directly and pay per query over x402 from its own wallet: search_subgraphs, get_subgraph_schema, query_subgraph. Query prices are variable, so each action probes the 402 price and enforces a per-query maxPaymentUsdc cap before signing. Base-only; reuses AgentKit's existing x402 signing stack (no new deps). Discovery + query construction ported from PayQL (Apache-2.0). Includes README, unit tests, and a changeset. Complements the managed `graphadvocate` provider with a direct/self-serve tier.

Description
Adds a
thegraphaction provider that lets an agent query The Graph directly and pay per query over x402 from its own wallet — no API key, no signup. Three actions:search_subgraphs— find the best subgraph(s) for a plain-English topicget_subgraph_schema— list a subgraph's queryable entities + argsquery_subgraph— run a GraphQL query against a subgraphQuery prices are variable, so each paid action probes the gateway's 402 price, enforces a per-query
maxPaymentUsdccap, and only then signs and pays. Base-only; reuses the same x402 signing stack as the built-inx402provider, so no new dependencies. Discovery + query-construction logic is ported from PayQL (Apache-2.0).This complements #1357 (the managed
graphadvocateprovider) as the self-serve tier:graphadvocate= pay an agent that does the routing/querying for you (no setup);thegraph= query The Graph gateway directly and pay your own way (cheaper, more control). Fits WISHLIST → "Trading & Data".Tests
