Onchain & crypto

Pre-registered overnight continuation read for the Robinhood-tradable crypto universe: the top-5 session-momentum coins into the 20:00 UTC signal, the BTC 200-day regime gate, and the study receipts. The ranking beat its random null at every fee tier in the cold study; at Robinhood retail fees the studied trade was REFUTED — a state read with its refutation attached, not advice. ~15-min refresh, 24/7.

Multi-chain portfolio snapshot with token balances and yield positions for a user's Otto AI Safe accounts across Base, Ethereum, Arbitrum, Polygon, BSC, Avalanche, and Solana.

The entry point for agents landing on CRYPTYX. Returns the full signal registry (every atomic and composite signal, all versions) with class, horizon, geometry, parameters, 30-day trigger stats, three-axis health grades, walk-forward IS/OOS — plus a meta.service block (universe + walk-forward + macro-regime + OKX/Kraken/Coinbase venues), a meta.by_class strategy-family breakdown, a meta.next recommended 5-step flow, and per-signal _actions with direct URLs to explain / backtest / fork / simulate. One call answers "what is CRYPTYX, what can I buy, and what should I call next". Signal evaluations run across the CRYPTYX 200+ tracked digital assets — BTC, ETH, SOL, top-cap + long-tail coverage.

Index scores for trading agents — how strong is each major index right now? One read returns the scored index row per book: S&P 500 (SPY) and Nasdaq-100 (QQQ) plus the macro and BTC/ETH crypto books — 0-100 opportunity score, percentile, green/yellow/red light and entry state for each index, with every book's regime verdict alongside. The cheapest top-down read of the whole tape. Refreshed ~5 min in market hours, timestamped. Research, not advice.

Base social intelligence: a Base sentiment read + quality-screened Base tokens (CoinGecko-listed, market-cap/age/liquidity gated) catching attention, each labelled with the basis it stands on (`rankedBy`: measured trusted-KOL signal, or the on-chain screen plus engagement), with KOL quotes inside a published window (`evidenceWindowDays`). Served from a cached snapshot while fresh (≤1h) and regenerated on demand when a read finds it stale.

Basis for one perpetual: mark versus oracle premium in percent and basis points, impact premium, current funding and the predicted next funding per venue. Use it when an agent is evaluating a cash-and-carry, comparing funding across venues or deciding whether a perp is trading rich or cheap to spot.

Cached in-process for 60 seconds.

Executable swap quote on Solana from Jupiter's aggregator: input and output mint, amount in base units, slippage in bps - returns out amount, minimum out after slippage, price impact percent, the routed DEX labels in hop order with split percentages, the USD value of the swap and the context slot. A real multi-hop route across Solana DEX liquidity, so the number reflects depth, not a spot price. Quote only - nothing is signed or sent. Keyless.
