Onchain & crypto

Native-coin balance + ERC-20 token balances (raw + human) for any address on Base, Ethereum, Arbitrum, Optimism, Polygon or BNB (default Base). On Base pass token symbols or 0x addresses (or a default common set); on other networks pass explicit 0x token addresses.

Market-wide screener of the biggest upcoming token unlocks across many crypto tokens in a forward window. Returns the largest scheduled unlocks ranked by USD value or by percent of circulating supply, each with its date, token amount and protocol. Bounded fan-out across the most active emitters. Data from DeFiLlama, cited.

Rich cross-source market report for 50+ assets (crypto, stablecoins, forex, metals): Chainlink + DEX pools, TVL-weighted VWAP, total pool TVL, recent change and volatility — all computed by us from on-chain state.

Trending Base DEX pools ranked by recent swap volume and net buy/sell flow over a short window, computed by us from public Aerodrome/Uniswap-V3 Swap event logs.

On-chain DeFi liquidation telemetry for Base lending protocols: recent LiquidationCall events decoded by us from public Base event logs — count, total debt repaid and collateral seized (USD), estimated liquidation bonus, per-protocol and per-asset breakdown, and the recent events (user, liquidator, collateral, debt).

Non-custodial swap calldata for Base: give tokenIn, tokenOut, raw amountIn, slippage and recipient; we read Aerodrome and Uniswap V3 on-chain state, pick the max-output route, and return ready-to-sign transaction calldata plus the ERC-20 approval, amountOutMin, price impact and the venues compared. You sign with your own wallet — we never hold or move funds.

Market-wide ranked solvency screen of all centralized exchanges from DefiLlama CEX Transparency: each row has solvency_score, rating, clean-asset ratio, own-token concentration, 1-week netflow percent and risk flags. Filter by min_score / max_own_token_pct / min_tvl; sort by score, tvl or outflow. Deterministic; reserves are a proxy, not proof of solvency.

Normalized Bitcoin DCA verdict: a single accumulate / hold / reduce signal with confidence and rationale, fusing AHR999, the Mayer Multiple, the Fear & Greed index and the 200-week MA deviation. Shows the input components and per-indicator scores. Keyless, deterministic, no LLM.

Flagship NFT collection intelligence: fuses identity, floor (native+USD), market cap, volume, total supply, holders and listed count into COMPUTED metrics — liquidity ratio (listed/supply + volume/mcap), holder/supply ratio, sales velocity and floor momentum — plus a normalized market-health verdict with confidence and rationale. EVM via CoinGecko, Solana + Bitcoin-Ordinals via Magic Eden. Keyless, attributed.

Best Solana liquidity-pool strategy for a token mint: finds the live LP pools holding the mint from keyless DefiLlama yields (Orca, Raydium, Kamino and other Solana venues), ranks them by TVL + fee-APY + 24h volume, and suggests a concentrated-liquidity price range from the pool's return volatility. Returns the best pool, alternatives, 24h fees and the suggested range.

Network health and token-economics verdict for a DePIN network from public data. Give network (helium) and get coverage size (IOT and MOBILE node counts), token supply for HNT, IOT, MOBILE and DC read on-chain, the emission and halving context, and a coverage-scale indicator. Each value is cited to its source.

Bitcoin AHR999 accumulation index: (spot / 200-day geometric mean) * (spot / exponential-growth valuation), with the accumulation zone (bottom / dca / wait), the raw components and a short interpretation. Keyless, computed from DefiLlama price history.

Identify what an EVM address IS in one keyless call: contract/protocol identity (entity, name, category) from Open Labels Initiative attestations with trusted-attester consensus, plus on-chain truth (is_contract, code_hash), reverse ENS/Basename, sanctions (OFAC/UK/EU/UN) and scam-drainer flags. Cited provenance; unknown addresses answer with empty labels, never a 404.

Standing-state audit of a wallet's live ERC-20 token approvals. Indexes every approval the address ever granted, filters to those still live on-chain, flags unlimited, stale, scam-listed and canonical spenders, estimates money-at-risk, and returns a ranked revoke plan with ready calldata plus a 0-100 risk and allow, warn or block verdict. Risk indicators, not advice.

Normalized corporate-insider transactions from SEC Form 3, 4 and 5 filings. Give a ticker or issuer CIK and get each director, officer and 10-percent-owner transaction: transaction code, security, shares, price per share, value, acquired or disposed, direct or indirect holding, the insider role, and the disclosure lag, every record cited to its accession and form4.xml URL.

Bitcoin block metadata by height or hash (or the chain tip when neither is given), fused with the current difficulty-adjustment context, a computed halving countdown and a network hashrate snapshot. Informational, not advice.

Perpetual basis for an asset: the mark-versus-oracle premium on venues that publish a native mark price (Hyperliquid), in basis points, with a naive annualized carry proxy. Shows how far the perpetual trades from the underlying oracle — a froth and leverage-cost signal.

Bitcoin hash-ribbon miner-capitulation signal: the 30-day versus 60-day moving average of network hashrate, whether miners are in capitulation, whether a recovery cross has occurred, and the 30-day hashrate trend. Informational, not advice.

Recommended Bitcoin transaction fee-rates in sat per vByte across five confirmation horizons (fastest, half hour, hour, economy, minimum) plus a live mempool congestion snapshot with an estimated block backlog. Informational, not advice.

Cheap raw normalized reserve breakdown of one centralized exchange: total on-chain reserves (currentTvl), clean-of-own-token reserves (cleanAssetsTvl), the own-token symbol / USD value / concentration, clean-asset ratio, spot & derivative volumes, leverage, 24h/1w/1m netflow and the public reserves URL, with citations. The cheap first grain before the fuller /cex/solvency verdict. Keyless DefiLlama source; reserves are a proxy, not proof of solvency.

Composite crypto market sentiment: the Fear & Greed index (value, classification, trend) blended with aggregated news-headline sentiment into one bullish/bearish/neutral score, optionally focused on a coin or query. Data by alternative.me (attributed) + curated RSS headlines.

Crypto Fear & Greed Index: the market Fear & Greed value, classification and trend, blended with aggregated crypto news-headline sentiment into one bullish/bearish/neutral score, optionally focused on a coin or query. Data by alternative.me (attributed) + curated RSS headlines.
