PaulieB14
PaulieB14 (GitHub handle of the Graph Advocate author; provider.organization in the published A2A agent card) operates Graph Advocate, an onchain-data routing agent for The Graph Protocol at graphadvocate.com. Agents send a plain-English blockchain data question over A2A JSON-RPC 2.0, REST or MCP and receive the best subgraph among 15,500+ indexed on The Graph, a ready-to-run GraphQL query and, on paid calls, the executed rows. Twenty-two paid endpoints add derived trader intelligence for Hyperliquid perps, Polymarket, Kalshi, Limitless and Uniswap plus natural-language SQL over x402 settlements on Base. There are no API keys or signups: paid calls settle in USDC on Base via x402 (HTTP 402 + PAYMENT-REQUIRED header), and the agent is registered as ERC-8004 agent #734 (Arbitrum) and #41034 (Base) under the ENS name graphadvocate.eth. The author also publishes six npx-installable MCP servers (Aave, Uniswap, Polymarket, lending, Limitless) that read The Graph directly.
PaulieB14 publishes 12 API contracts indexed on the APIs.io network, including Agent API, Ask API, Hyperliquid API, and 9 more. Tagged areas include Blockchain, On-Chain Data, The Graph, Subgraph, and GraphQL.
PaulieB14’s developer surface includes documentation, getting-started guide, API reference, pricing, authentication, and 24 more developer resources.
