Skills (26)
Agent reputation score (0-100, on-chain derived)
agent_scorePOST /agent/score {wallet, days?=30}. Composite 0-100 reputation score for any Base wallet. Combines three on-chain ground-truth axes: identity (ERC-8004 registration on Base + IPFS metadata), activity (USDC settlement velocity), and reputation (ERC-8004 feedback + validation registry events, aggregated across all agents owned by the wallet). Hard 8004 gate filters out burn addresses, USDC contract, and CEX hot wallets — settlement signals alone don't distinguish agents from sinks. Tier output: active_verified / active / registered_or_settling / dormant_low_signal / no_evidence. Cached 24h. Use for: should I integrate / pay / trust this peer agent. $0.02 USDC per call on Base.
Find the best subgraph for any protocol
find_subgraphSearches 15,500+ subgraphs across 20+ chains to find the best one for your data need. Returns the subgraph ID, a ready-to-run GraphQL query, query volume (reliability signal), and a playground link to test it. Free API key at thegraph.com/studio — 100K queries/month, 2 min signup.
Hyperliquid recent fill stream + bid/ask flow
hyperliquid_fillsPOST /hyperliquid/fills {coin, n?}. Recent perp fill stream for a Hyperliquid coin (BTC, ETH, HYPE, etc.) — last N fills (max 10) with side, price, size, notional, direction (OPEN_SHORT/CLOSE_LONG/…), payer, fee, liquidations. Includes a flow summary: buy/sell counts, notional totals, whale-fill flag (≥$10k notional). Distinct from /screen (which ranks traders); this surfaces events for real-time tape-watching. $0.02 USDC per call on Base.
Hyperliquid full PnL (per-coin breakdown)
hyperliquid_pnlPOST /hyperliquid/pnl {user}. Full per-coin breakdown: realized_pnl, total_funding, total_fees, liquidation_fills, volume_bought/sold, first/last trade timestamp per coin. For agents auditing a trader's exposure surface or feeding deeper reputation signals. $0.05 USDC per call on Base.
Hyperliquid liquidation + funding risk
hyperliquid_riskPOST /hyperliquid/risk {user}. Liquidation rate, funding burn rate, leverage pattern indicator, and 24h activity flags for a Hyperliquid trader. For agents evaluating counterparty perps exposure or building risk-aware copy-trade filters. $0.02 USDC per call on Base.
Hyperliquid trader skill score (perps)
hyperliquid_scorePOST /hyperliquid/score {user, coin?}. Composite skill_score (0-100) for any Hyperliquid perps trader: 40% profitability (realized + funding) + 40% risk (liquidation rate, drawdown proxy) + 20% efficiency (fees vs volume). Returns classification (sharp/neutral/retail/insufficient_data), liquidation_rate, funding_burn, sample_size_trades. Wraps Pinax /v1/hyperliquid/users with risk signals Polymarket can't have (binary outcomes). $0.02 USDC per call on Base.
Hyperliquid top traders by coin (skill + risk)
hyperliquid_screenPOST /hyperliquid/screen {coin, n?}. Top N (default 10, max 10) traders of a Hyperliquid coin (BTC, ETH, SOL, etc.), ranked by total_volume, each with skill_score, sharp/retail/insufficient_data classification, liquidation_rate, and funding burn. Pre-trade check for perps market-makers and copy-trade scouting. $0.05 USDC per call on Base.
Hyperliquid vault evaluator (copy-trading)
hyperliquid_vaultPOST /hyperliquid/vault {vault}. Evaluates a Hyperliquid copy-trading vault: leader skill_score, redemption pressure (withdrawals/deposits ratio), depositor concentration, commission rate, last-activity recency. Hyperliquid Vaults = native copy-trading; no Polymarket equivalent. Unique vs Hypurrscan / Hyperdash human dashboards. $0.10 USDC per call on Base.
Kalshi consensus trend (slope + acceleration)
kalshi_consensus_trendPOST /kalshi/consensus-trend. Consensus slope and acceleration for a Kalshi market from its forecast history — is the crowd moving, and is the move speeding up. $0.05 USDC per call on Base.
Kalshi ↔ Polymarket cross-source spread
kalshi_polymarket_spreadPOST /kalshi-polymarket/spread. Shows where Kalshi and Polymarket disagree on the same event, two ways: `pairs` when the venues word a question alike, and `reconciled` when they do not — Kalshi states a threshold on the level ('upper bound above 3.75%'), Polymarket a delta ('25 bps increase'), so for macro markets like Fed rates the wording never matches and only the distribution comparison works. Differences are reported in bps AND bounded by the venues' quote widths, so you can tell signal from noise; it does not claim a tradeable edge. A JOIN neither venue can answer alone. $0.05 USDC per call on Base.
Kalshi live sports edge (play-by-play vs candles)
kalshi_sports_live_edgePOST /kalshi/sports-live-edge. Live sports mispricing: play-by-play state against the market's own candles, surfacing where the price has not caught up with the game. $0.05 USDC per call on Base.
Narrative vs on-chain flow divergence (JOIN)
narrative_divergencePOST /narrative/divergence {chain?, limit?, cohort?}. Ranks trending tokens by the gap between social momentum (Cambrian deep42: tweet velocity, unique authors, reach) and on-chain flow ACCELERATION from a Uniswap subgraph — recent volume against each token's own baseline, so it measures activity rather than token size. Surfaces tokens loud on social but quiet on-chain, and the reverse: real flow nobody is tweeting about, which a social feed structurally cannot see. Ticker squatters are filtered by most-transacted claimant; non-EVM symbols are reported in `unresolved`, never dropped. $0.05 USDC on Base.
Get live onchain data (balances, swaps, NFTs, holders)
onchain_dataReturns live blockchain data via Token API — wallet balances, token transfers, DEX swaps, NFT sales, holder rankings. Works across EVM (Ethereum, Base, Polygon, Arbitrum), Solana, and TON. No subgraph needed for these queries.
On-chain x402 address summary (decentralized)
onchain_x402_addressPOST /onchain-x402/address {address}. Read-only lookup against the x402 Base subgraph on The Graph Network: returns the address's lifetime x402 stats (totalPayments, totalVolumeDecimal, firstPaymentTimestamp, lastPaymentTimestamp) broken out by role (payer + recipient), plus the most-recent 10 payments in each direction, facilitator metadata if the address is a registered facilitator, and indexed_through_block so the caller can judge data freshness vs. chain tip. Decentralized, verifiable, no centralized data warehouse dependency. Distinct from /ask (which queries x402-watch's R2 parquet warehouse via Anthropic). $0.01 USDC per call on Base.
Polymarket prediction markets — prices, OHLCV, positions, P&L, activity
polymarket_dataRoutes Polymarket queries to the Pinax Prediction Markets API (Token API `/v1/polymarket/*`). Covers markets discovery, OHLCV per outcome token, open interest, activity feeds (trades, splits, merges, redemptions), user positions with realized/unrealized PnL, and platform-wide aggregates. Preferred over the graph-polymarket-mcp package for common queries — cleaner REST surface, no npm install, AI-ready structured responses.
Polymarket leaderboard (derived skill metrics)
polymarket_leadersPOST /polymarket/leaders. Top Polymarket traders with derived skill metrics per trader — score, classification, sample size — rather than raw volume alone. $0.02 USDC per call on Base.
Polymarket full PnL (per-position, mark-to-market)
polymarket_pnl_fullPOST /polymarket/pnl {wallet}. Full PnL report: derived skill metrics plus per-position aggregates — net position, average buy price, current price, realized and mark-to-market unrealized PnL per market. For agents that need position-level detail — audit, debug, or feed into a deeper reputation signal. $0.05 USDC per call on Base.
Polymarket trader skill score (quick)
polymarket_pnl_quickPOST /polymarket/pnl-quick {wallet}. Pure-JSON skill metrics for any Polymarket trader: skill_score (0-100, Sharpe-weighted by confidence), classification (sharp/neutral/retail), win_rate, sample_size, max_drawdown, realized + unrealized PnL. No lot reconstruction — designed for batch screening top holders before entering a market or vetting a copy-trade signal. $0.01 USDC per call on Base.
Polymarket ghost-fill counterparty risk
polymarket_riskPOST /polymarket/risk {wallet}. Classifies a Polymarket maker by ghost-fill risk via Polygon eth_getCode + ERC-1967 implementation slot probe. Returns wallet_type (eoa | smart_account_erc1967 | legacy_smart_account), ghost_fill_risk (low/medium/high), and a 24h collateral outflow flag. Polymarket's new POLY_1271 / sig type 3 deposit wallets are ghost-fill-immune by design; legacy EOAs / Safes carry the historical risk that LPs have been getting burned by. $0.02 USDC per call on Base.
Polymarket size-the-room (top holders + skill + ghost-fill risk)
polymarket_screenPOST /polymarket/screen {condition_id, n?}. Returns the top N (default 10, max 10) position holders of a market, ranked by position size, each with skill_score, sharp/retail/insufficient_data classification, AND ghost-fill risk per holder. The pre-trade check for trading and market-maker agents — answers 'who am I about to be against, and will their fills actually settle?' $0.02 USDC per call on Base.
Polymarket ↔ Limitless cross-venue spread (JOIN)
predmarket_spreadPOST /predmarket/spread {topic, limit?}. Cross-venue arbitrage spread on a topic keyword: pulls matching markets from Polymarket (Gamma public API) and Limitless (REST public search), pairs them by closest-price match, returns per-pair yes-mid spread (bps) and arbitrage_direction. JOIN that single-venue passthroughs structurally can't return — GA is the place agents go to compare prediction markets across venues. Naive pair-up by price proximity; agent should confirm semantic match (same end date, same resolution source) before sizing. $0.05 USDC per call on Base.
Uniswap spot ↔ Hyperliquid perp basis (JOIN)
uniswap_basisPOST /uniswap/basis {coin, chain?=ethereum}. Cross-venue JOIN: Uniswap spot price vs the Hyperliquid perp for one asset, returning basis_pct and a perp_premium / perp_discount / aligned signal. A spot-vs-perp comparison single-venue passthroughs structurally can't return. $0.05 USDC per call on Base.
Uniswap pre-trade due-diligence (V2/V3/V4, 6 chains)
uniswap_pretradePOST /uniswap/pretrade {token, chain?=ethereum}. Pre-trade check for a token on Uniswap: real liquidity, the deepest venue ranked by volumeUSD (NOT TVL — TVL is gamed by spam-token pricing), a honeypot two-way-flow check, daily volume trend, and a tradeable/risk verdict. Powered by The Graph across Uniswap V2/V3/V4 on Ethereum, Arbitrum, Base, Polygon, Optimism and BSC. $0.02 USDC per call on Base.
Uniswap per-wallet flow: accumulators vs distributors
uniswap_tradersPOST /uniswap/traders {token, chain?=ethereum}. Per-wallet flow on a token's deepest Uniswap venue: accumulators vs distributors with trader EOAs, buys/sells and volume_usd — see who is actually building or unloading a position. Powered by The Graph. $0.02 USDC per call on Base.
Write a GraphQL query for any subgraph
write_queryGiven a data need, returns a complete ready-to-execute GraphQL query with the correct subgraph ID, entity names, and field selections. Just add your free API key and POST to the gateway. Works with any HTTP client — no SDK or MCP required.
x402 Base settlements Q&A (NL→SQL)
x402_settlements_askPOST /ask {question}. Natural-language Q&A over a custom 132M-row Cloudflare R2 parquet warehouse of every x402 EIP-3009 USDC settlement on Base mainnet, May 2025 → Jun 2026. Anthropic Sonnet + DuckDB translate plain-English to SQL against two virtual tables: settlements (row-level) and daily_stats (pre-aggregated, 388 days). Returns {answer, sql_trace, model, upstream_ms} — sql_trace makes the data path inspectable so callers can verify the answer wasn't hallucinated. $0.05 USDC per call on Base.
