Subgraph Registry

Agent-friendly semantic classification of all subgraphs on The Graph Network.

Pre-computed index of 14,700+ subgraphs with domain classification, protocol type detection, schema fingerprinting, canonical entity mapping, and composite reliability scoring.

The Problem

Agents querying The Graph need to discover and select the right subgraph before they can query data. Today this requires 3-4 tool calls (search, check volumes, fetch schema, infer structure) before any real work happens. This registry flips that: agents start with structured knowledge, not a blank slate.

What It Does

Crawls all active subgraphs from the Graph Network meta-subgraph
Fetches the GraphQL schema for every deployment
Classifies each subgraph by domain, protocol type, canonical entities, and schema family
Scores reliability using on-chain signals (query fees, volume, curation, stake)
Returns x402 + legacy query URLs — agents can pay $0.01 USDC on Base per query (no API key) or use a Studio key
Publishes as SQLite database + REST API + MCP server
Generates visual dashboards and bot-readable category files (auto-updated with each sync)

Querying with x402 (no API key)

Every result includes query_url_x402 alongside the legacy query_url. The Graph's public x402 gateway (live since 2026-05-08) accepts $0.01 USDC on Base per query with zero signup.

// An x402-native agent — discovery to data in two calls
const { recommendations } = await mcp.call("recommend_subgraph", {
  goal: "find DEX trades on Arbitrum",
});
const top = recommendations[0];

// POST your GraphQL query. The first call returns HTTP 402 with a
// base64 `payment-required` header; the x402 client signs the
// EIP-3009 USDC transfer on Base and retries automatically.
const data = await x402Fetch(top.query_url_x402, {
  method: "POST",
  body: JSON.stringify({ query: "{ swaps(first: 5) { id amountUSD } }" }),
});

Pricing manifest returned per subgraph:

{
  "amount_usd": 0.01,
  "asset": "USDC",
  "asset_contract": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",

}

Client libraries: @graphprotocol/client-x402, x402-fetch, or any generic x402 wrapper.
