Available tools 14

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

text

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 extraction: no third-party reader service is resold.

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 from invoices, emails, messages, logs or documents. Pass fields or a JSON schema to receive exactly the fields you need. Same input, same output, in milliseconds.

code

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.

dex

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.

domain

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 infrastructure review and integration pre-checks.

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 not probe individual mailboxes, so catch-all domains may still accept addresses that do not exist.

fear

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 trading. Data published by alternative.me for free commercial use with attribution; served from a 30-minute cache.

hash

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.

language

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.

phone

phone-lookup

Parse a phone number locally against the numbering plan using libphonenumber metadata. Returns format and number-plan validity only; current network assignment and subscriber status are not queried. data_source = "numbering plan (libphonenumber)".

rates

fx-rates

Live foreign-exchange reference rates from the European Central Bank (ECB), updated every business day. Convert between 30+ currencies (USD, EUR, GBP, JPY, CNY and more) with a single call: pass base and symbols, get mid-market reference rates as clean JSON. Rates are the ECB daily reference rates, the same source banks and accounting tools cite. Free reference data, republished with attribution.

sec

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.

ssl

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 integration pre-flight.

timestamp

timestamp-convert

Convert Unix seconds, Unix milliseconds or an ISO date to UTC and Asia/Shanghai timestamps. An empty object returns the current time.

call402 — x402 Agent Services — questions

Answers built from our own checks of this server.

What can call402 — x402 Agent Services do?

It exposes 14 tools, read directly from the server on our last check. Among them: dex-quote, domain-lookup, email-verify, fear-greed-index, fx-rates, hash-tools and 8 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is call402 — x402 Agent Services working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 1159 ms. The bar chart above shows every period we have measured.

Did call402 — x402 Agent Services ever remove tools?

Yes. token-quotes, token-risk-summary, trending-pools, wallet-activity-summary and 1 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect call402 — x402 Agent Services?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does call402 — x402 Agent Services need an API key?

No. call402 — x402 Agent Services completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 14 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is call402 — x402 Agent Services?

It answers our handshake in 1159 ms on average, which is faster than 3% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
