Rewrite serviceName (≤32), description (≤500), tags (≤5) for buyer-query rank. Warns on first-index freeze.

Bitcoin network health: hashrate, difficulty, transaction count, estimated volume, miner revenue and the largest recent mempool transactions. A congested mempool carrying large transfers can front-run an exchange flow you will only see in price an hour later.

Crypto Fear & Greed Index: current reading (0-100, Extreme Fear to Extreme Greed) plus 7-day and 30-day sentiment trend (rising/falling/flat with the average and point change), not just a single snapshot number. Not ticker-specific. Data from alternative.me. $0.01/call.

Crypto Fear & Greed Index: current and previous value with classification, plus recent history. A contrarian input — extreme fear has historically marked accumulation zones and extreme greed distribution zones — but it is a filter, never a trigger on its own. Pair it with funding to separate real capitulation from a crowded short.

Real crypto market data in one batched call: price, market cap, market-cap rank, 24h volume/high/low/change, circulating/total/max supply, and all-time-high with date -- for BTC, ETH, SOL, and 17+ other major coins by ticker. Richer than a plain price feed: most stock-data APIs' crypto tickers report null market cap. From CoinGecko. $0.005/call.

Live USD spot prices for crypto assets via CoinGecko simple price API

Total value locked across DeFi, the top chains by TVL, and aggregate stablecoin market cap. Stablecoin supply is the dry powder of the whole market: rising supply with rising TVL is risk appetite expanding, falling supply is capital genuinely leaving crypto rather than rotating inside it.

Deposit into the Ink Balanced Yield USDC vault ($0.01 fee on top of the deposit amount).

BTC, ETH and USDT dominance as a share of total crypto market cap — the regime filter to check before sizing any altcoin position. Rising BTC dominance means capital rotating to relative safety; rising USDT dominance means capital leaving for stablecoins, a broader risk-off. Falling BTC dominance with rising ETH dominance is the classic rotation signal.

Weather and soil-moisture anomalies for 10 commodity-growing regions (precipitation, temperature, root-zone soil wetness; Open-Meteo ERA5 + NASA POWER, 1994→) from El Niño Market Watch.

Daily NoFA signal from El Niño Market Watch: a deterministic, rules-based LONG/SHORT pick across 21 ENSO-sensitive assets — expected return to the strong-scenario peak, historical hit-rate with Wilson 95% CI, CFTC COT crowding penalty, full rationale, plus the live paper portfolio (NAV, positions, trades). Simulation, not investment advice.

El Niño event composites from El Niño Market Watch: 14 historical events (1951–2026) across 21 commodities, indexed-to-100 price paths around event onset with median/p25/p75 envelopes — the computed asset behind the dashboard charts.

Latest ENSO index bundle from El Niño Market Watch: weekly Niño 1+2/3/3.4/4 SST anomalies (NOAA CPC), RONI, Troup SOI (BOM) and weekly IOD/DMI — recent tails with exact source URLs.

Ethereum address activity: ETH balance plus recent large transfers in and out. Point it at an exchange wallet, a treasury or a wallet a headline just named, and get the movement behind the story rather than the story.

FullEnrich People Search — filter by company domain/name/LinkedIn URL, seniority, title, location, skills, industry, job function, tenure, and 20+ other FullEnrich filters. Requires at least one filter; limit/offset alone → 400.

Funding rate and open interest for one coin, broken down venue by venue across Binance, Bybit and OKX, using each venue's largest-open-interest perpetual. Use it when venue divergence matters: one venue far more positive or negative than the rest is localised positioning, not market consensus — the setup that precedes a squeeze on that venue alone. Returns per-venue rows plus average funding, total open interest and the spread.

Perpetual funding rate and open interest for up to 10 coins in a single call, across Binance, Bybit and OKX. Answers 'where is the leverage right now?' for a whole watchlist at once instead of one symbol at a time. Thin venues are excluded: averaging every venue that publishes a rate overstates BTC funding by ~30x, because a near-empty book printing 9% per 8h counts the same as a deep one. Funding in percent per 8h, open interest in USD.

Generate a list of odd numbers up to a specified limit.

Generate a random handshake sequence (numbers and symbols) for secure connections.

Convert Gregorian dates to Hijri (Umm al-Qura calendar) and back. Returns day/month/year, Arabic and English month names, and a formatted Arabic date string. Essential for agents handling Islamic events, Ramadan, Hajj seasons, or Arabic documents.

Use when you have a company domain and need to know what the company is before spending more. Returns the company name and site title, domain age, registrar, mail provider, DNS provider, DMARC and HTTPS status, and a count of the third-party vendors detected. One call, no signup, no API key. The cheapest way to qualify a domain before buying a fuller record.

Use when you need to reach a company rather than a named person: the emails, phone numbers and social accounts it publishes about itself, gathered from its own site. Also returns every third-party vendor the company can be proven to use, with the record proving each. For support, sales and abuse contact discovery from a domain.

What the options market expects price to do, not what leverage is doing: the 30-day implied volatility index for BTC and ETH, with its percentile over the last month and the expected move in percent over 1, 7 and 30 days. Funding tells you who is crowded; this tells you how much movement is already priced in — and whether hedging is cheap or expensive relative to where it has been.

Machine-consumable web3 integration-risk decision for buyer agents ($0.10).

Monitor recent official Israeli company-registry changes for an exact nine-digit company number. Returns filing and status-change events newest first, with dates, deterministic categories, source URLs, and checked_at. Use for counterparty monitoring, supplier due diligence, onboarding refreshes, corporate-event alerts, and registry change detection. Coverage is approximately one year.

The macro regime that actually drives crypto, from official US sources: Fed funds rate, 2Y and 10Y Treasury yields, CPI inflation year-over-year and the dollar index. Crypto is a duration asset priced against the dollar and the front end of the curve — a funding spike during a DXY breakout means something different from the same spike into a cut.

Whether the current reading is actually high or low, from a series captured every ~10 minutes: funding, open interest, Fear & Greed and BTC dominance, each as current, median, min, max and percentile over the window. A funding rate of 0.006% means nothing on its own; at the 89th percentile of the last 24 hours it means something. This is the question a snapshot endpoint cannot answer, whoever you buy it from.

Day's biggest gainers and losers screened from the entire market, live from Yahoo Finance. Each mover includes ticker, company name, current price, intraday change amount and %, and volume — the market context every trader needs. Not ticker-specific. Supports optional limit per list (default 10, max 25). $0.01/call.

Market risk sentiment in one call, live from FRED: volatility index (VIX), high-yield and investment-grade credit spreads, financial conditions index, US dollar strength, and WTI crude oil price — the 6 metrics that flag systemic risk and market-wide stress. Replaces 6 separate FRED lookups for traders monitoring macro volatility and risk-off sentiment. Not ticker-specific. $0.01/call.

Recent crypto headlines for narrative context and catalysts — the qualitative layer that explains why funding moved when no macro print did. Returns headlines with attribution for summarisation, not article text.

OFAC SDN screen — fuzzy-screen a person or organization name against the public OFAC SDN list (including aliases). Returns scored potential matches. Not clearance.

Extract the main readable plaintext of a public HTML page: final url, title, text (capped), wordCount, language, and fetchedAt. POST JSON {"url":"https://example.com","maxChars":12000}. Optional maxChars is an integer 1–12000 (default 12000). Public http(s) only; private hosts blocked. $0.05 USDC on Base (eip155:8453). No API key.

Real-time risk-weighted USDC lending APY on Base: Aave/Compound/Morpho read onchain, Moonwell/Euler/Fluid via DefiLlama, source tagged per reading (never estimated). EIP-712 signed by the payment-receiving address (see X-Signal-* headers), which also holds an ERC-8004 identity and attests readings on-chain via EAS. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.

Returns random text string for testing

Search the catalog of every cataloged Earth-orbiting object — ~69,000 satellites, rocket bodies, and debris tracked by US Space Force / 18 SDS (via CelesTrak SATCAT). Filter by name (q, e.g. "starlink"), owner/launching country (owner — code like US/PRC/CIS or a name like "china"), object type (type = payload | rocket body | debris | unknown), launch-year range (launchYearFrom/launchYearTo), international/COSPAR designator prefix (intlDesignator, e.g. "2024-"), on-orbit vs decayed (onOrbit), or exact NORAD number (noradId). Each result carries the NORAD id, name, international designator, object type, owner + resolved country, launch date + site, decay date (null = still in orbit), and orbital parameters (period, inclination, apogee, perigee). The envelope total is the full count matching your filter — so onOrbit=true&type=payload answers "how many active satellites are up there", and owner=PRC tells you who launched them. For a satellite's live sub-point position, pass its noradId to

Scheduled macro catalysts ahead — FOMC, CPI, PCE, Non-Farm Payrolls, GDP, Retail Sales — from the official US release calendar. The dates that decide whether a position should be sized down before the print. Returns the scheduled release, not analyst consensus.

Search the live web for current information. Returns fresh structured organic search results with titles, URLs, snippets, domains, and ranks for agent research and retrieval.

The answer, not the inputs. One call returns a stance for the coin — risk-on, risk-off, fragile or neutral — built from funding and open interest percentiles, sentiment, options implied volatility, the macro regime and what it costs to execute at your size. Every driver comes back with its number and its reading, plus the conditions that would invalidate the call. The rules are deterministic: the same market gives the same verdict.

The total US public debt outstanding to the penny — the headline national-debt figure — split into debt held by the public and intragovernmental holdings, with the latest value, prior business day, day-over-day change, and recent history. No ticker needed. Updates each business day. Sourced from the US Treasury (FiscalData). Pass `?limit=` for more history (default 30, max 250). From x402stock

Calculate Euler totient function phi(n) for a given positive integer n.

S&P 500, gold and Nasdaq 100 quotes as the traditional-market leg of a crypto read. BTC trades as a high-beta risk asset far more often than as digital gold, so equities direction is usually the better correlation to check before blaming a crypto-native cause. Priced as ETFs, so use direction and percent change, not the absolute level.

US Treasury yield curve in one call: 1mo/3mo/6mo/1yr/2yr/5yr/10yr/30yr yields, the 10y-2y and 10y-3mo spreads, and a boolean inversion flag on each -- a classic recession/risk-off signal every macro trader watches. Live from FRED's daily constant-maturity Treasury series. Not ticker-specific. $0.01/call.

The daily US Treasury par yield curve (Constant Maturity Treasury rates) for every maturity from 1 month to 30 years, in percent. Defaults to the latest published day; pass `?limit=` for more recent days (max 250) and `?year=YYYY`. No ticker needed. Use for the risk-free rate, rate-sensitivity context, and yield-curve inversion in macro-aware analysis. From x402stock

Agent-ready keyword trend intelligence for 1-5 keywords in a country. Returns normalized relative-interest data. Not Google Trends.

Agent-ready keyword trend intelligence for 1-5 keywords in a country. Returns normalized relative-interest data. Not Google Trends.

Large ETH transfers (>100 ETH) to and from known exchange wallets in the last 2 hours. Inflows to exchanges are potential distribution pressure, outflows suggest accumulation or a move to cold storage — but read them as context, not instruction: a single large transfer is often internal rotation between wallets of the same desk.

What a trade actually costs before it is placed: live order book depth on Bybit and OKX, walked at your size. Give it a notional in dollars and it returns the average fill price, slippage against mid in basis points and dollars, the spread, the depth within 1% of mid, and which venue is cheaper for that exact size — separately for buying and selling. A size the book cannot absorb is reported as unfilled, never priced by extrapolation.

asset dispatch for autonomous agents

dappgrade score — pre-transaction health/safety verdict for an onchain app, by contract address. Returns ok / caution / avoid / unknown with the coverage the verdict rests on.

Use before paying an x402 endpoint you have not used before, when you cannot tell a working seller from a trap, a testnet address dressed as mainnet, or a listing whose price no longer matches its challenge. Returns a verdict — live, degraded, trap, testnet or dead — a 0-100 risk score, and the specific findings behind both, so an agent can decline a bad endpoint instead of learning about it by losing the money. Costs less than the smallest payment it protects.
