AI agents need to pay for things. That's a harder problem than it sounds. If an agent pays $0.0001 for a data query but the gas fee is $0.05, the economics fail entirely.
GraphTally, the trust-minimized micropayment system built by core developers on The Graph, has been live on the network since late 2024 and directly shaped the x402 specification to solve exactly this problem.
AI agents don't browse block explorers. They query, decide, and act thousands of times a minute.
An agent asked to assess DeFi risk can't parse raw logs. It needs structured, normalized, queryable data.
The agent economy runs on infrastructure most people never see.
This is the infrastructure shift that makes agent-native data real.
No API key. No account. No monthly plan. A wallet is all an agent needs to query onchain data through The Graph's x402 gateway, paying one cent per query in USDC on @Base.
Pair that with Subgraph discovery, and the whole workflow runs in two steps.
An AI agent needed onchain data. It had one question and one cent.
No API key. No signup form. No GRT required.
The Subgraph Registry found the right Subgraph. x402 handled the payment. The agent got its answer in under a second.
This is what agent-native data infrastructure looks like.
When The Graph launched Subgraphs, they became the first widely adopted open standard for indexing smart contract data. Not because it was mandated, but because it worked.
Open standards that belong to the public are how the decentralized internet gets built.
Is indexing a solved problem?
It came up at a recent panel on blockchain data.
The short answer: no.
70+ chains. Different VMs. Different client implementations. Hundreds of protocol-specific contracts. DEX trades alone required integrating 150+ protocols before a coherent data format emerged.
This is why The Graph has spent years building industry-leading data solutions.
The official Agent0 Subgraphs are now live on @base, @BNBCHAIN, @ethereum, @monad_xyz, and @0xPolygon.
Real-time indexing for every ERC-8004 agent — identity, capabilities, reputation, validation. Built as a public good with @graphprotocol.
The Graph Gateway now supports x402 payments.
Any agent or application can query Subgraph data by paying per request in USDC. No API key, no account, no session.
Here's what that means and how to use it 🧵
3 years ago, sequential indexing was enough. Then @Solana. @Base. @BNBCHAIN .
Chains that generate transaction volumes sequential processing can't keep pace with.
The paradigm shifted from APIs to streaming, and that shift is why Substreams exists.
For any enterprise considering doing indexing work in-house, it is sometimes harder than it looks. Definitely reach out to some of the folks who have been doing this from the very beginning.
The Graph set the standard.

Markets, OHLC, OI, activity, positions, users, on-chain and queryable.
Blockchain collapses the settlement timeline from days to seconds. When the @The_DTCC ran its Great Collateral Experiment, settlement that once took one to three days happened in seconds.That's the upside.
The downside is that when data is wrong in a real-time system, there is no buffer.
The implications and how The Graph helps ⬇️
Getting accurate, real-time prices from decentralized exchanges is not simple. Running the infrastructure is expensive.
Led by @graphopsxyz, Tycho on The Graph Network delivers DEX liquidity data through a single streaming interface, handling the reorg complexity and multi-chain coverage so trading systems and solvers do not have to.
Public beta scheduled to launch in Q2 2026.
If autonomous AI agents really are going to start transacting with each other on-chain, what's the first product you'd want built on top of an ERC-8004 reputation index?
The Graph just made every agent on @base, @BNBCHAIN, @ethereum, @monad, and @0xPolygon queryable within milliseconds.
Curious what you'd build.

What can you actually ask once this is running?
❓"Compare USDC borrow rates across all protocols right now."
❓"What positions does this wallet have open across all protocols?"
❓"Show the top 10 markets by TVL on @arbitrum."
No GraphQL. No custom adapters. Just a question to Claude and a live answer from The Graph's indexed data.
