XML to JSON converter. XML to JSON for any XML document: attributes become "@name" keys, text becomes "#text" (or the value itself when an element only holds text), and repeated child elements become arrays. DOCTYPEs and external entities are refused, so nothing outside the document is ever loaded. Up to 100,000 characters. Use to read XML feeds, SOAP responses and config files in an agent.

Address checksum (EIP-55). Address checksum for any EVM address: validates it and returns the EIP-55 checksummed form, saying whether the input was all lower case, all upper case, correctly checksummed or mixed case with a wrong checksum (a likely typo).

Uses public DNS only and sends no mail. Use before a campaign, when

MCP server check, inspector. MCP server check over streamable HTTP: whether it answers initialize, its name, version, protocol version and capabilities, whether it needs sign-in (OAuth or another 401 challenge), and its tools with names, titles, descriptions and input parameters, plus prompt and resource counts. Read-only: it lists, never calls a tool. Use to vet an MCP server before adding it to

Language detection for a text: the most likely language with its ISO 639-3 and 639-1 codes and English name, plus the next candidates with relative scores, using trigram statistics for 82 major languages (franc-min). Works best above about 20 characters; very short or mixed text returns und (undetermined). Local, no outside service. Use to route messages, pick a translation target or filter conten

Bitcoin address balance and activity for any mainnet address (legacy, P2SH or bech32): confirmed balance in sats and BTC, unconfirmed pending amount, total received and sent, and transaction counts. Use for payment verification, checking whether a deposit arrived, and wallet monitoring.

Package risk check. Reports package existence, latest version and release, age, version count, npm weekly downloads, licenses, deprecation and known advisory severity. ok means no listed flags, not a safety guarantee. Supports npm, PyPI, Cargo, Go, Maven and NuGet. Optional exact version adds pinned-version metadata and uses deps.dev advisories; use /package-audit for OSV affected ranges and dated

Weather forecast. Weather for any city or point on Earth (city name, or latitude and longitude): current temperature in Celsius, conditions (clear, cloudy, rain, snow), precipitation in mm, wind, humidity, cloud cover and air pressure, plus an hourly forecast for up to 48 hours.

Check a Dockerfile (up to 8,000 characters) for common security and image-size problems: unpinned or :latest base images, running as root, piping downloads into a shell, sensitive values baked into ENV or ARG, ADD from URLs, apt and pip cache left in layers, sudo, chmod 777 and an exposed SSH port. Returns each finding with its line, a severity and a fix, plus a score. Use before building or shipp

Returns the message you send, with its length and the server time. Use to test an x402 client, payment flow or agent tool wiring end to end.

Decode a BOLT11 Lightning Network invoice without paying it: network, amount in sats and BTC, description, payment hash, creation time, expiry time and whether it has already expired. Use to check what an invoice asks for before an agent pays it.

Returns a risk level, score and findings with excerpts. Heuristic, not a guarantee. Use before acting on untrus

A fair random yes or no, with a cryptographic random source. For quick decisions when the options are equally good. Use to break ties.

Fast check of a payee before an agent pays it: OFAC SDN match on the address, account type (wallet, delegated wallet or contract) and nonce on Base, Ethereum, Arbitrum, Optimism or Polygon, and optionally the payee domain's age and trust flags.

One block, review or pass verdict with reasons. Never signs. Screening aid, not legal advice. U

Web page to Markdown, rendered. Same output as /extract, but the page is first rendered in a real browser, so single-page apps and pages that build their content with JavaScript come back with their text instead of an empty shell.

Uptime check, website status. Check whether a website is up right now: one live request (following redirects) with the HTTP status, up or down, response time in ms, the final URL, content type, server header and page size, and optionally whether the page contains a given text. Timeouts and connection failures come back as down with the reason, not as an error. Use for uptime monitoring, health che

Base gas-cost estimates. Estimates Base gas costs from current fees and priority-fee presets. Fixed gas units (100k simple, 250k complex, 180k liquidity) are typical assumptions, not transaction-specific estimates or quotes. Valid values: standard, high-mev (3x priority fee), low-gas (half); invalid values return HTTP 400 without charge. No transaction simulation, mempool observation, or MEV/sandw

API health check. One call to health-check an API endpoint: up or down with status and response time over three requests (min, median, max), the redirect chain, HTTP security headers, whether it is a paid x402 endpoint and what its payment terms are, and the API's OpenAPI document when one is found at the usual places.

Website audit, security audit. One call to audit a website: is it up and how fast, the redirect chain (including whether plain http moves to https), the on-page SEO audit with its score and issues, HTTP security headers and their grade, robots.txt for the page, and the domain's DNS, email authentication and registration age. Server-side HTML only, no JavaScript. Cheaper than the six tools bought o

Sourced token and wallet risk. Combines the Base token-report risk tier and flags, available DEX market data, and wallet-audit risk tier, flags, account nonce, and native balance.

Wallet risk check. Screen a Base address for fresh or throwaway-wallet signals: a high/medium/low heuristic risk tier with named flags (no or one outgoing transaction, a near-empty balance with few transactions), plus ETH, USDC, WETH, cbBTC and DAI balances and the account nonce.
