## Tools (as reported by the server, not verified)

- `text-to-structure`: Turn unstructured text into strict, machine-readable JSON for agent pipelines: a deterministic, reproducible alternative to an LLM extraction call. Extracts emails, URLs, EVM wallet addresses, transaction hashes, ISO-normalized dates, money amounts, percentages, phone numbers and key:value pairs fro
- `fx-rates`: Daily foreign-exchange reference rates for the major fiat currencies \(USD, EUR, CNY, GBP, JPY, HKD and more\) from the European Central Bank via Frankfurter: convert amounts, price in a local currency, or sanity-check a rate before a payment. Give a base currency and optional symbols and amount. Refe
- `email-verify`: Email address validation for signup screening, lead cleanup and form verification: syntax check, disposable/temporary-domain detection and a live MX-record lookup for the domain. Returns a deliverability verdict \(likely\_deliverable, risky, undeliverable, invalid\_format\) with the MX hosts found. Does
- `fear-greed-index`: Crypto Fear & Greed Index by alternative.me: current value \(0-100\) and classification \(Extreme Fear, Fear, Neutral, Greed, Extreme Greed\) plus optional daily history. The most-cited single market-sentiment gauge for crypto trading agents: position sizing, risk checks and regime detection before trad
- `text-extract`: Extract the readable main content of any public web page as clean text: send a URL, get the page title, excerpt and body text with navigation, ads and boilerplate stripped \(Mozilla Readability, computed on our own servers\). For RAG ingestion, summarization, research and page monitoring. First-party
- `ssl-check`: TLS/SSL certificate check for any public host: issuer, subject, SAN list, validity window, days until expiry, SHA-256 fingerprint and whether the certificate chain verified. Computed by a direct TLS handshake from our own servers. For uptime and security monitoring agents, vendor endpoint checks and
- `domain-lookup`: Domain one-stop lookup: live DNS records \(A, AAAA, CNAME, MX, NS, TXT via DNS-over-HTTPS\) plus RDAP registration data \(registrar, creation and expiry dates, status, nameservers\) assembled from public protocol endpoints on our servers. For domain due diligence, phishing-site checks, counterparty infr
- `qr-code`: Generate a QR code image for any text, URL or payment address: returns SVG markup or a base64-encoded PNG rendered on our own servers \(qrcode library, MIT\). For agents that produce scannable payment requests, links, addresses or tickets but cannot render images themselves.
- `sec-company-facts`: Summarize a US public company's latest SEC-reported Revenue, NetIncomeLoss and Assets from official EDGAR companyfacts. Look up by ticker, CIK or company name; returns filing dates and fiscal periods. Uses SEC public-domain data with a declared User-Agent.
- `language-detect`: Detect the most likely language of text entirely on this server, with ISO 639-1 language code, language name, confidence and alternatives. Supports English, Chinese, Japanese, Korean, Spanish, French, German, Russian, Portuguese and Italian; no upstream request.
- `timestamp-convert`: Convert Unix seconds, Unix milliseconds or an ISO date to UTC and Asia/Shanghai timestamps. An empty object returns the current time.
- `hash-tools`: Run local cryptographic utilities: SHA-256 and SHA-512 hashes, Base64 encode/decode, or a random UUID v4. No upstream service is called.
- `dex-quote`: Self-computed long-tail EVM token quotes from public on-chain DEX pools on Base, BNB Smart Chain and Ethereum. Discovers Uniswap V2/V3 and PancakeSwap pools with eth\_call; majors are excluded. V3 depth is estimated. Informational only.
