x402 support means AI agents can query The Graph Network and pay per-query, autonomously, with no pre-configured API keys, no setup in Studio.
The agentic web doesn't wait for setup.

The Graph is the indexing protocol for blockchain data, helping developers organize and query onchain data with subgraphs and GraphQL.
July 25 • ethglob.al/HKRXP56HKA
One of the most important architectural decisions when building a blockchain application is how you get your data. Subgraphs or Substreams?
The answer depends on what you're building⬇️
Every ERC-8004 trustless agent on @base , @BNBCHAIN, @ethereum , @monad , and @0xPolygon is now indexed by The Graph.
Millisecond-fast discovery, reputation queries, and capability search across the open agent economy.
Subgraphs on The Graph Network now accept x402 payments directly. Agents and apps can pay per query in USDC over HTTP, no API key, no account, no session.
Pair that with GraphTally settling Gateway-to-Indexer payments underneath, and you get machine-native payment end-to-end.

Subgraphs or Substreams: which blockchain data solution should you choose?
➡️Subgraphs: structured, queryable onchain data for user-facing apps.
➡️Substreams: high-throughput pipelines that sink data anywhere.
How to pick, and how to move between them ⬇️
Why GraphTally reads like x402, a year early: sub-cent, high-frequency, trust-minimized.
Instead of transferring tokens per query, gateways attach a signed Receipt to each request, an IOU processed offchain in microseconds with no gas fees. Indexers aggregate those Receipts into
Everyone is talking about x402 and machine-native payments. The Graph Network has run the same pattern in production since early 2025: GraphTally.
Pay-per-query, no accounts, signed offchain, trust-minimized. And Subgraphs now accept x402 directly.

Not all stablecoins carry the same risk.
Fiat-backed, crypto-collateralized, and delta-neutral each have different failure modes, collateral dynamics, and data requirements.
An institution that can't distinguish them in its risk system isn't ready for the coming regulatory
Substreams move issuance events, redemption flows, and transfer activity from the chain into any environment an institution is building.

MiCA is live. The GENIUS Act is moving.
Institutions that built data infrastructure before the rules arrived move on day one. Institutions that waited spend the first months catching up while competitors lock in relationships.
The data exists. It's all onchain. The gap is
The agentic web needs onchain data.
Subgraphs deliver structured, queryable onchain state: fast access to token prices, governance votes, NFT ownership, protocol activity.
Substreams power the high-performance pipelines AI teams use for model training and real-time inference.
Neither replaces the other. They solve different parts of the same problem.
Subgraphs and Substreams are the onchain data layer the agent economy depends on.
