19 tools live on Keryx.
8 of them are for trading agents — live Solana onchain data, rug scoring, market signals, price feeds. Every tool is a real HTTP endpoint; every call pays the publisher in USDC.
The rest wrap high-quality public sources for general agent tasks (weather, geo, search, web). Keryx is the payment, discovery, and settlement layer — not a replacement for free web browsing.
Solana onchain
3 toolsSolana Token Activity
Live trading data for a Solana token: top DEX pairs, 24h volume, buy/sell counts, liquidity, and market cap.
New Solana Token Launches
Freshly-boosted Solana token profiles from DexScreener with descriptions, links, and dex URLs.
Solana Rug Risk Score
Live risk assessment from rugcheck.xyz: numeric score, normalised score, LP lock percentage, and every flagged risk.

3 toolsExchange Rates
Live fiat + crypto exchange rates for any base currency (200+ currencies). Call when you need current rates for a specific conversion or comparison you will show the user.
Currency Converter
Convert an amount from one currency to another using live rates. Only call when you are actually going to perform and display a specific conversion for the user.

Market signals
2 toolsTrending Cryptos
The most-searched coins on CoinGecko right now, with price, 24h change, market cap, and rank.

Live BTC and ETH dominance percentages plus total crypto market cap from CoinGecko. Worth calling when the agent needs a broad market regime signal before making allocation or timing decisions.
Search
1 toolsWikipedia Grounded Search
Factual search over Wikipedia. Returns page titles, short extracts, and URLs. Best for definitions, history, geography, notable facts, and established knowledge. NOT for prices, availability, bookings, current events, commercial recommendations, or live data.

Top stories from Hacker News: title, url, score, comments, time.
GitHub Repo Info
Public repo metadata: stars, forks, description, language, license, last push.
Weather
2 toolsCurrent Weather
Live current weather for any lat/lon. Worth paying for when the user needs up-to-the-minute conditions (travel today, outdoor plans, severe weather). Not needed for general city descriptions.
Weather Forecast
Hourly + daily forecast for a location (up to 7 days). Worth it for concrete near-term travel or event planning. Not needed for generic 'Berlin has seasons' advice.
Geo & IP
2 toolsIP Geolocation
Location, ISP, ASN, timezone and security flags for an IP (or caller's IP). Only useful when the user's actual location or network context materially affects the answer (e.g. local currency, nearby services, compliance).
Country Info
Basic country data: capital, population, currencies, languages, region. Mostly useful for structured lookup when building a specific comparison or form. General knowledge about Germany is usually sufficient.
DNS & domains
1 toolsDomain WHOIS
Registrar, creation/expiry dates, name servers and status for a domain name.
Utilities
3 toolsQR Code
Generate a QR code image URL for any text (URL, text, wallet address, etc.).
Current Time
Precise current time in unix seconds, ISO, and human formats. Call when the agent must not hallucinate the date or needs a fresh timestamp for logs, expiries, or time-based decisions.
UUID v4
Generate a random UUID v4. Useful when an agent needs a unique identifier for plans, sessions, or objects it is creating.
