Agent0 Subgraphs Launch Across Five Major Blockchains with The Graph Protocol
Agent0 Subgraphs Launch Across Five Major Blockchains with The Graph Protocol
🤖 Agent data goes live
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 RPC calls
- Millisecond response times across all five chains
- Already processed over 1M queries
- Built as a public good with The Graph Protocol
Practical applications:
- Agent marketplaces and discovery
- Real-time reputation dashboards
- Cross-chain analytics
- Agent-to-agent interactions
Developers can now access comprehensive agent data without building custom indexers. The unified schema works across all supported chains with a simple parameter change.
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 Launches x402 Payment System for Subgraph Queries
**The Graph's Subgraph Gateways now support x402 payments**, enabling pay-per-query access using USDC on Base. **Key features:** - Query blockchain data across dozens of networks without API keys or accounts - Payment serves as authentication in a single HTTP round trip - Client receives 402 response with price, signs USDC payment, retries and receives data - Existing API-key access remains unchanged **Technical implementation:** - x402 endpoints available at `/api/x402/...` - Compatible clients can install via `npm install @graphprotocol/client-x402` - Works on Base mainnet and Base Sepolia testnet This payment model is particularly useful for AI agents and applications needing on-chain data like DEX activity, positions, governance, or protocol metrics without managing authentication infrastructure. [Read the documentation](https://thegraph.com/docs/en/subgraphs/guides/x402-payments/)
Graph Protocol Launches x402 Payment Package with Three Integration Options
**The Graph Protocol** has released a dedicated x402 package (`@graphprotocol/client-x402`) offering developers three integration methods: - **CLI one-liner** for quick implementation - **Programmatic API** for flexible integration - **Typed SDK** with complete type safety The package supports **USDC payments** on Base and Base Sepolia networks. Developers can install via npm and access full documentation at thegraph.com/docs. [Install package](https://www.npmjs.com/package/@graphprotocol/client-x402)
🔓 The Graph Drops API Key Requirement for Network Access
**The Graph Network is removing a major friction point for developers.** Previously, accessing Subgraph data required a Subgraph Studio account and API key - a setup that worked fine for traditional apps but created barriers for: - Autonomous agents - Serverless functions - Ephemeral workloads that spin up and down This change makes The Graph more accessible for modern, dynamic infrastructure patterns without requiring persistent credentials.
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.
