Global crypto market snapshot: total market cap, total 24h volume, BTC dominance, ETH dominance, active coin count, active exchange count, and 24h market-cap change %. Returned in a chosen vs_currency (default usd). Backed by CoinGecko /global.

Historical price, market cap, and volume time series for a coin. Granularity is automatic per CoinGecko: <=1 day = 5-min bars, 2-90 days = hourly, >90 days = daily. Days: 1, 7, 14, 30, 90, 180, 365, or "max". Returns aligned arrays of {time, price, marketCap, volume}.

RSI, MACD, EMA 20/50/200, SMA 20/50, Bollinger bands, ATR and VWAP computed deterministically from live candles for one coin and interval, with the latest series points and a plain-language summary. Use it when an agent needs standard technical indicators without fetching candles and computing them itself.

Top N coins by market capitalization with full market snapshot per coin: rank, price, 24h change, 7d change, 24h volume, market cap, circulating supply, and all-time high. Default 10, max 100 per call. Backed by CoinGecko's public API.

The whole crypto perp market in one call: advancers versus decliners, mean, median and volume-weighted 24h change, total open interest and volume, top contracts by volume, the day's gainers and losers, funding extremes and BTC and ETH at a glance. Use it when an agent needs a market snapshot before deciding what to look at next.

Recent crypto headlines aggregated from the public feeds of major outlets, deduplicated and newest first, each with title, source, publish time, canonical URL and a short summary, filterable by keyword, source and time window. Use it when an agent needs what happened in the last hours rather than what a model was trained on.

The options chain for a currency and expiry sorted by strike: bid, ask, mark, mark implied volatility, open interest, 24h volume and the underlying, plus the list of available expiries. Use it when an agent is pricing a strategy, finding liquid strikes or reading the volatility smile for a specific expiry.

L2 order-book snapshot for a spot pair: best bid/ask, mid price, spread (absolute + %), and the top N aggregated price levels per side (default 25, max 100). Pairs use BASE-QUOTE format (BTC-USD, ETH-USD, SOL-USDC). Backed by Coinbase Exchange's public market-data API - keyless; coverage is Coinbase-listed markets.

Use it when an agent needs a current crypto price to size, compare or display, or a cheap read to poll on a schedule.

Trending coins on CoinGecko in the last 24 hours, ranked by user search activity on the site (currently ~15 results). Includes coin id, symbol, market cap rank, current price (BTC-denominated), and score. Useful signal for detecting narrative shifts before they hit price charts.

Validate CSV structure: consistent column counts across rows, properly closed quotes, delimiter detection. Returns row/column counts and any structural errors. Pure CPU.

Parse CSV (quoted fields supported) into a JSON array of objects, using the first row as headers (header=false for arrays).

Convert CSV into a GitHub-flavored Markdown table (first row is the header).

Look up a CVE by id, or search CVEs by keyword or product: the NVD description, CVSS severity and vector (v4.0, v3.1, v2), CWE weaknesses, affected products and versions (CPE), and reference links, joined with the EPSS exploitation probability (next 30 days) and whether CISA lists it as a known exploited vulnerability (date added, due date, ransomware use). This product uses the NVD API but is not endorsed or certified by the NVD.

Difference between two dates/times in ms, seconds, minutes, hours, days, and a human summary.

Parse a datetime from any format (ISO 8601, Unix timestamp in seconds or milliseconds, RFC 2822, or natural date string) and return it in every common format: ISO 8601, Unix (seconds), Unix (ms), RFC 2822, date-only, time-only, day of week, and human-relative (e.g. '3 days ago').

Get the day number within the year (1-366) for any date, plus days remaining, leap-year status, percent of year complete, and a simple (Sunday-start) week number.

Describe a job and get a call-ready plan: which tools, across this catalog and outside x402 sellers with a recently verified 402, solve it end to end, in what order, with fallbacks, input params that validate against each tool's schema, and cost/latency estimates. Priced by depth: quick (one best tool), plan (steps + fallbacks), full (plan + params + compiled prompt). The fee comes back as a credit toward running the plan with POST /api/decide/execute.

Run a decision's plan through Agent402: first-party steps run directly, third-party steps are paid on your behalf (paid on Base, or by credits or card) and relayed at the seller's price plus a disclosed routing fee. Priced at the plan's budget (or your maxBudgetUsd, whichever you set) less a valid execution credit; spend stops at that budget, fallbacks are tried in order, and any unspent amount comes back as a credit. A run where no step succeeds is not charged.

Remove duplicate lines, preserving first-seen order. Returns the deduped text and how many were removed.

Daily total value locked history for one chain or for all of DeFi, up to ten years of points, with latest, first, minimum, maximum and mean and the change over the window. Use it when an agent is charting a chain's growth or checking whether a TVL move is new or a return to trend.

Blockchains ranked by DeFi total value locked with each chain's share of the total, native token, EVM chain id and CoinGecko id. Use it when an agent is comparing chains by DeFi activity or needs the canonical ids to query other services about a chain.

Decentralized exchanges ranked by 24h spot volume with 7d, 30d, 1y and all-time volume, change, the chains each trades on and sector totals. Use it when an agent needs to know where onchain spot volume is happening or how a DEX's share is moving.

Protocols ranked by fees paid by users or by revenue kept, with 24h, 7d, 30d, 1y and all-time totals, change, category and chains, and chain-level gas fees on request. Use it when an agent is comparing protocols on real usage rather than TVL or valuing a token against the fees its protocol earns.

One DeFi protocol in full: TVL rank, TVL per chain, recent change, market cap to TVL, token, website, audits and parent, with name suggestions when the slug is unknown. Use it when an agent is researching a specific protocol and needs its size, footprint and audit status in one answer.

DeFi protocols ranked by total value locked, filterable by category, chain or name, each with rank, chains, TVL, 1h, 1d and 7d change, market cap and the market cap to TVL ratio. Use it when an agent needs the league table of protocols or wants to find the largest lending, DEX or staking venues on a chain.

Look up the current Total Value Locked (TVL) for a DeFi protocol via DeFiLlama's public API. Identify the protocol by its DeFiLlama slug (uniswap, aave, lido, ethena, etc.). Returns the total TVL plus per-chain breakdown and 24h/7d/30d change where DeFiLlama exposes it.

Daily APY and TVL history for one yield pool, up to ten years, with a summary of latest, minimum, maximum and mean APY and the TVL change over the window. Use it when an agent is judging whether a pool's current yield is typical or an outlier before allocating to it.

Live yield opportunities across DeFi, filterable by chain, protocol, token symbol, stablecoin-only, minimum TVL and minimum APY: pool identity, TVL in dollars, total APY split into base and reward, 1-day, 7-day and 30-day APY change, impermanent-loss risk and exposure type. Use it to find, compare or monitor where a given asset earns the most right now.

What agents keep asking for that nobody serves yet: aggregated, qualified demand clusters from a live agent-demand board, with caller counts and how long each need has persisted. Use it when a seller or an agent is choosing what to build next and wants unmet demand with evidence instead of guesses.

Search FDA medical-device recall / enforcement records (openFDA): recalling firm, classification (Class I/II/III), reason, distribution, and dates. Live FDA data, no key.

Look up the Uniswap V3 pool address for a token pair + fee tier on Ethereum, Base, Polygon, Arbitrum, or Optimism. Pass either order (tokenA/tokenB) - the factory sorts internally. Returns 0x0…0 if no pool has been deployed for that combination yet.

Read on-chain state of a Uniswap V3 pool: token0/token1 addresses + decimals, fee tier, current sqrtPriceX96, tick, in-range liquidity, and the decoded human-readable spot price (token1 per token0). One $0.002 call replaces ~6 RPC roundtrips on the caller's side.

Spot quote for swapping through a Uniswap V3 pool at the current tick. amountIn is in human units (not wei). zeroForOne=true sends token0 → token1; false sends token1 → token0. Returns amountOut net of the pool's fee tier. NOTE: this is a single-tick spot quote - slippage from depleting concentrated liquidity is NOT modeled. Use for indicative pricing; for production swaps quote against the Uniswap SDK.

Top DEX pools (Uniswap, Sushi, Curve, Aerodrome, etc.) ranked by current TVL - filterable by chain and project. Sourced from DeFiLlama's public Yields API (keyless). Each row carries chain, project slug, symbol pair, TVL in USD, current APY, and pool ID for follow-up queries.
