Bitcoin address lookup for agents: confirmed and pending balance in BTC and USD, total received and sent, transaction count and the latest transactions with net amount, confirmations and fee. Works for bc1 (SegWit, Taproot), 1 and 3 addresses on Bitcoin mainnet. Use to check a payment, a treasury or a counterparty wallet.

LLM chat completions. Send a prompt, get an answer from Meta's Llama 4 Scout (17B active, 16 experts), with an optional system prompt, up to 1,024 output tokens and adjustable temperature. Fast and cheap. Use for drafting, reasoning steps, Q&A and any quick LLM call without an AI provider account; other open models by name at /v1/chat/completions, harder reasoning at ai_chat_large.

Verify an OpenTimestamps proof (.ots as base64, from btc-timestamp or any ots client): upgrades pending proofs from the calendars, checks each Bitcoin attestation against the real block's merkle root and returns status (confirmed, pending), block height and time, the upgraded proof, and whether your text, hash or URL matches.

Web page to markdown (read URL as clean text) for LLM agents: main content only (no nav, cookie banners, ads), with title, description, author, dates, language, headings, internal/external links and JSON-LD types, PLUS a prompt-injection scan of the page (visible text, hidden HTML, comments, invisible Unicode) so your agent knows whether the content tries to give it orders. Fetched from Cloudflare's edge, ~0.5 s. Unreachable pages are not charged.

Read an ERC20 token contract on Base, Ethereum or IOTA EVM mainnet: name, symbol, decimals, total supply, and optionally the balance of one holder address. Verifies that the address is a contract. Params: token (contract address, required), chain ('base' default, 'ethereum' or 'iota-evm'), holder (optional address).

Live US airport disruptions from the FAA National Airspace System status: ground stops, ground delay programs (average and max delay), arrival and departure delays with trend, and closures. Pass airports (IATA like JFK or ICAO like KJFK) for a per-airport status (normal, delays, disrupted; general-aviation-only closures are listed as notices) or omit them to get all current events. US airports only. Params: airports (optional list).

Keyword ideas for a seed keyword, each with Google search volume, CPC, competition, keyword difficulty and search intent; up to 100 ideas in one $0.04 call (Google Ads data). Use when you need related keywords to target. volume = avg monthly searches, cpc in USD, competition 0-1, difficulty 0-100. No ideas returns empty results (still charged). Bad input is free; upstream errors are not charged.

Currency exchange rates (forex): official ECB reference rates for about 30 currencies (USD, GBP, CHF, JPY, CNY, ...), published every working day around 16:00 CET, cross rates for any base among them. Returns rates object mapping currency codes to rates relative to base. Pass symbols array to filter (e.g. ['USD','CHF','GBP']). Empty symbols = all supported currencies. Use for currency conversion in invoices, pricing, or financial calculations.

Generate a QR code for any text or URL. Returns image_base64 (base64 PNG; decode to get raw bytes). Params: text (required), size in px (64-1024, default 256), error_correction (L/M/Q/H, default M). H = highest redundancy, survives up to 30% damage.

Give it domains. For each it reads SPF, DMARC, DKIM and MX over keyless DNS-over-HTTPS and composes an anti-spoofing posture with specific findings and a signal (protected / mostly-protected / monitoring-only / spoofable / no-email-configured). Read-only DNS, agent-callable. One search per call (result caps in the input schema); failed lookups are not charged.

Recent Transfer events of an ERC-20 token (newest first, up to 50): tx, time, from, to, amount in token units. Optional holder filters to transfers from or to one wallet. Reads up to the last 12000 blocks (fewer on very busy tokens) via RPC, so it is cheap but not a full history; the response says what range was searched. Use for quick wallet or token activity checks.

Search developer sources in one call: Hacker News stories (Algolia), GitHub repositories (by stars), npm packages (with weekly downloads), PyPI (exact package lookup, PyPI has no search API) and Stack Overflow questions. Each source returns its own list; a source that is rate limited reports an error without failing the call. Params: query (required), sources (default all: hackernews, github, npm, pypi, stackoverflow), limit per source (1 to 20, default 5).

Drop-in Exa-compatible contents: send urls (or ids) and text / highlights options exactly as for Exa /contents and get results with id, url, title, author, publishedDate, text and highlights plus per-URL statuses, as clean markdown with a prompt-injection verdict. Up to 10 URLs for $0.004. Not affiliated with Exa.

Drop-in Firecrawl-compatible scrape: send {url, formats: [markdown, links, rawHtml]} as for Firecrawl v1 /scrape and get {success, data: {markdown, links, rawHtml, metadata: {title, description, language, sourceURL, statusCode}}} with a prompt-injection verdict, at $0.005. Fetched from Cloudflare's edge. Not affiliated with Firecrawl.

Web search API for AI agents, an Exa alternative that costs less: Google-quality results re-ranked for authority (primary sources first) and merged with research papers (arXiv, Semantic Scholar), GitHub repos, news and Wikipedia when the query needs them. Optional category (news, research paper, github, financial, company, pdf, docs), region and time filter. Median ~1.7 s. Up to 10 results per call.

Validate an EU VAT identification number live against the official EU VIES service, with registered company name and address where the member state discloses them. Checks the national format first. Not charged if the member state service is temporarily unavailable. Params: vat_number (with country prefix, e.g. NL004495445B01, DE811569869) or vat_number + country_code.

Find libraries and repositories for a coding task: GitHub repositories ranked by stars and relevance (popular, maintained ones first; under 30 stars dropped) plus npm packages for JavaScript / TypeScript, with description, stars, last push or publish date and links.

Honeypot and rug check before a trade, built for trading bots that check every token in a loop: up to 5 token addresses per call (Base, Ethereum, BSC, Arbitrum, Polygon, Avalanche, Optimism or Solana), one decision each: ALLOW, CAUTION or BLOCK, with grade A to F, score, honeypot flag and the main reason. Based on our own on-chain checks (contract code, pools, real buy and sell simulation). Results are cached for 10 minutes, so repeat checks answer in milliseconds.

Business day calculator for SLAs, invoice due dates, shipping and legal deadlines: counts working days between two dates, skipping weekends and national public holidays (ISO country code).

Currency exchange rates (European Central Bank reference rates) for price conversion, invoicing and travel budgets. Latest or historical by date.
