The Graph

**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.

**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 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 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 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.

A new blockchain data tool called **graph-aave-mcp** now connects Claude AI with live Aave protocol data across seven chains. **Key capabilities:** - Simulate health factors during price crash scenarios - Track liquidation events in real time - Compare supply and borrow rates across different deployments - Monitor governance proposals through conversation The tool is powered by The Graph Protocol's indexed data and requires just one npm install to access every major Aave deployment. **Who benefits:** - Risk analysts can model scenarios conversationally - DeFi researchers gain real-time market insights - Builders can prototype dashboards by describing requirements - Content creators can query live data while writing The tool eliminates manual GraphQL queries, unit conversions, and stale data snapshots—users simply ask questions in plain English.

The Graph is rolling out three institutional-grade tools for real-time blockchain data: **Substreams** delivers high-performance data streaming for DeFi, DePIN, AI, and traditional finance applications. Horizon integration scheduled for Q2-Q4 2026. **Amp** introduces a SQL-native blockchain database with verifiable data designed for enterprise scale. Developer preview is currently live, with full SQL platform launching Q4 2026. **Tycho** provides real-time onchain liquidity indexing specifically built for trading systems and solvers. Private MVP expected Q1 2026, public beta Q2 2026. These tools aim to bridge the gap between blockchain data and enterprise applications, offering familiar interfaces like SQL alongside specialized streaming capabilities for time-sensitive use cases.

**The Graph is rolling out three new data access tools designed for developers and AI agents:** - **Subgraphs**: The original indexing standard now supports AI compatibility through MCP integration, A2A protocols, x402 micropayments, and Amp-powered data extraction - **JSON-RPC**: Basic blockchain read/write functionality through The Graph's infrastructure (experimental launch planned for Q3) - **Token API**: Pre-indexed token data across 10+ chains with real-time pricing (production-ready in Q1) These tools build on The Graph's recent infrastructure developments for the agent economy, including ERC-8004 identity verification across 8 chains and x402 micropayment capabilities through GraphTally. The additions provide developers with multiple options for accessing blockchain data, from natural language queries to direct API calls.

The Graph has released its 2026 Technical Roadmap, outlining plans to expand from a single protocol into a multi-service blockchain data infrastructure platform. **Key developments include:** - **Six specialized data products** designed to serve different use cases - **Horizon unified protocol layer** to integrate services - **Expanded user base** targeting developers, AI agents, analysts, and financial institutions - **Enhanced capabilities** spanning real-time streaming to SQL analytics The roadmap signals The Graph's evolution from a focused indexing protocol to a comprehensive data infrastructure serving the broader onchain economy. The platform aims to accommodate users ranging from individual developers to large-scale institutional operations.

**The Graph is participating in ETHDenver** with multiple events covering privacy tech, AI agents, and institutional connections. **Key Event:** - Co-hosting an exclusive VIP Institutional Soirée with Halborn Security, Blockaid, and Canton Network on February 19 - Located 7 minutes from the main conference venue - Focus on connecting institutional leaders in digital assets **Topics covered across events:** - Privacy technology - AI agents - Institutional partnerships Registration is now open for attendees interested in connecting with The Graph team at the conference.
