Agent0 Subgraphs Launch Across Five Major Blockchains with The Graph Protocol
Agent0 Subgraphs Launch Across Five Major Blockchains with The Graph Protocol
🤖 Agents get indexed
Agent0 Subgraphs are now live across Base, BNB Chain, Ethereum, Monad, and Polygon, providing real-time indexing for ERC-8004 agents.
What's being indexed:
- Agent identity and capabilities
- Reputation scores and validation data
- Cross-chain agent activity
Key features:
- Single GraphQL query replaces complex blockchain scanning
- Millisecond response times with no RPC limits
- Unified schema works across all five chains
- Already processed over 1M queries
Built with The Graph Protocol as a public good, the subgraphs enable developers to query agent data without building custom indexers. This infrastructure supports emerging use cases like agent marketplaces, runtime discovery, reputation dashboards, and cross-chain analytics.
The launch addresses a fundamental need as AI agents begin transacting autonomously on-chain, requiring structured, real-time blockchain data at machine scale.
The agent economy will generate machine-scale demand for blockchain data. Thousands of queries per minute from agents that don't sleep, don't get bored, and don't accept rate limits. If you're building on ERC-8004 — you don't need to build an indexer. We already did. 🔗
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 Agent0 Subgraphs are now live on: @base @BNBCHAIN @Ethereum @Monad @0xPolygon One unified GraphQL schema across all five. Switch chains with a parameter, not a rewrite.
AI agents are about to start hiring each other, discovering each other, paying each other, and rating each other. Each one of those interactions needs structured, real-time blockchain data. The Agent0 Subgraphs are now indexing all of it. 🧵

One GraphQL schema. Five mainnets. Zero rewrites. The Agent0 Subgraphs are live on @Base, @BNBCHAIN, @Ethereum, @Monad, and @0xPolygonFdn — indexing every ERC-8004 agent on every chain in real time. Search "agent0" on Graph Explorer. 👇 thegraph.com/explorer?searc…
What this unlocks: → Agent marketplaces → Runtime agent-to-agent discovery → Reputation dashboards and trust scores → Cross-chain analytics → Real-time monitoring Things that used to take a custom indexer are now one GraphQL query.

If you're building an ERC-8004 agent, you have two options for discovery: →Scan thousands of blocks per chain, parse events, fetch IPFS files, fight RPC limits, and pray. →Send one GraphQL query to an Agent0 Subgraph. Pick option 2. The Graph already built it.

Things that are now a single GraphQL query thanks to the Agent0 Subgraphs: → Every active MCP agent across 5 chains → Top-rated agents by capability → Full reputation history for any agent → Cross-chain ERC-8004 adoption stats → Real-time feed of new registrations All
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
The Graph Gateway Launches x402 Payment System for Subgraph Queries
**The Graph Gateway has introduced x402 payment support**, enabling direct pay-per-request access to Subgraph data without API keys or accounts. **Key features:** - Pay per query using USDC on Base or Base Sepolia - No registration, API keys, or session management required - Payment serves as authentication - One HTTP round trip: request → 402 response with price → sign USDC payment → retry → receive data **Implementation:** - Install via npm: `@graphprotocol/client-x402` - Access endpoints at `/api/x402/...` - [Documentation available](https://thegraph.com/docs/en/subgraphs/guides/x402-payments/) **Use cases:** Particularly useful for AI agents requiring onchain data like DEX activity, positions, governance, or protocol metrics. The system is live and available for testing on both Base mainnet and Base Sepolia testnet.
The Graph Launches x402 Payment Package with Three Integration Options
**The Graph protocol has released a new dedicated package** for x402 payments: `@graphprotocol/client-x402` Developers can integrate it three ways: - **CLI one-liner** - fastest implementation method - **Programmatic API** - for custom integrations - **Typed SDK** - includes full type safety for TypeScript projects **Payment options:** USDC on Base mainnet or Base Sepolia testnet **Get started:** - Install: `npm install @graphprotocol/client-x402` - [Documentation](https://thegraph.com/docs/en/subgraphs/guides/x402-payments/) The package enables developers to implement blockchain data payment flows directly into their applications.
🔓 The Graph Removes API Key Requirement for Network Access
**The Graph Network is changing how developers access Subgraph data.** Previously, querying Subgraphs required a Subgraph Studio account and API key - a setup that worked for traditional apps but created friction for: - Autonomous agents - Serverless functions - Ephemeral workloads that spin up and down This barrier made it difficult for modern, dynamic applications to integrate blockchain data seamlessly. **The change enables more flexible access patterns** without the overhead of persistent credentials, particularly benefiting short-lived processes and automated systems that need to query data without manual setup.
Agent0 Subgraphs Now Live Across Five Mainnets with Unified GraphQL Schema
**Agent0 Subgraphs are now operational across five major blockchain networks** - Base, BNB Chain, Ethereum, Monad, and Polygon - using a single GraphQL schema. **Key features:** - Real-time indexing of every ERC-8004 agent across all chains - No code rewrites needed when switching between networks - Already processed over 1 million queries - Accessible via [Graph Explorer](https://thegraph.com/explorer?search=agent0) **What this enables:** - Developers can query agent data with a single GraphQL request instead of scanning thousands of blocks - AI agents can discover, hire, and interact with each other using structured blockchain data - Machine-scale data access for agents that operate continuously The infrastructure indexes agent identities, capabilities, reputation, and validation data in milliseconds. Developers building ERC-8004 agents can now access comprehensive onchain data without building custom indexers.
