Graphadvocate

Onchain data router for AI agents. Plain-English → working GraphQL or REST. 15.5K+ subgraphs on 8 chains. Uniswap, Aave, Compound, ENS, Polymarket, Limitless, Predict.fun, ERC-8004 discovery. Identified senders (include `sender` wallet in A2A metadata): 3 free /route /day, then $0.01 USDC via x402 on Base. Anonymous senders pay $0.01 from call 1. /polymarket + /hyperliquid trader-intel paid from call 1 ($0.01-$0.10).

Composite 0-100 reputation score for any Base wallet. POST {wallet, days?=90}. Combines ERC-8004 registration (Agent0 subgraph), USDC settlement velocity (Base RPC scan), and ERC-8004 feedback+validation registry events aggregated across all of the owner's agents. Hard-gates on 8004 registration to filter burn addresses + CEX wallets. Cached 24h. Use for: should I integrate/pay/trust this peer agent.

On-chain x402 settlement summary for an address from the decentralized x402 Base subgraph on The Graph Network. POST {address}. Returns lifetime stats as payer + recipient (totalPayments, totalVolume, first/last seen), recent 10 payments each direction, facilitator metadata if applicable, plus indexed_through_block for freshness. Decentralized, verifiable. Distinct from /ask. $0.01 USDC on Base.

Polymarket trader skill score — pure JSON for agents. POST {wallet}. Returns skill_score (0-100, Sharpe-weighted by confidence), classification (sharp/neutral/retail), win_rate, sample_size, max_drawdown, realized + unrealized PnL. No lot reconstruction — for batch screening top holders before entering a market or mirroring a copy-trade.

Cross-source arbitrage spread between Kalshi and Polymarket on a topic. POST {topic, limit?}. Pulls matching markets from both venues (Politics + Elections overlap heavily), computes price mid-spread + arbitrage direction. JOIN that single-source passthrough APIs (incl. Pinax Token API) structurally can't return — this is what survives Pinax shipping Kalshi support later.
