Textokit

Validate an Argentine CUIT or CUIL tax id: format and check-digit verification, normalized and formatted forms, declared type (CUIT or CUIL). Use this when an agent collects Argentine customer or supplier ids and must reject typos before invoicing, KYC or onboarding. Mathematical validation only: it does not confirm registration or ownership. JSON, no model inference. Free sample at /api/cuit-ar/sample. Also works as Argentina TIN or taxpayer ID validation.

x402 payment test and ping: one call with no required parameters returns server time (ISO 8601 and Unix ms), a request id, the seller payTo, chain id and an echo of your optional text, only after a real settlement. Use this when an agent needs to prove its payment flow works, measure round-trip latency or run a cheap scheduled canary against a live seller. No upstream, no model inference; paid round trip 1 to 2 s. Free sample at /api/x402-ping/sample.

Web page to Markdown or plain text: fetch one public URL and get its title and main content with scripts, styles, navigation and ads stripped, plus character count and truncation flags. Use this when an agent needs to read a URL for research, RAG, monitoring or summarization without an API key or a browser. One HTTPS fetch of static HTML (no JavaScript rendering, no login pages), up to 20,000 characters, JSON out. Free sample at /api/web-read/sample.

Crypto price in USD for bitcoin, ethereum, solana and up to 20 coins per call by CoinGecko id: spot price, market cap, 24h change, provider update time and source URL. Use this when an agent needs a current BTC, ETH or token price before a quote, a conversion, a report or an alert, with a citation it can re-check. Live from CoinGecko's public API, no key, JSON, no model inference. Free sample at /api/crypto-prices/sample.

FX rates and currency conversion reference: daily exchange rates for up to 20 currencies against one base (USD, EUR, GBP, JPY, BRL, MXN, ARS and about 160 more) with rate, reference date and source URL from Frankfurter (central-bank data, MIT licence). Use this when an agent needs an official-style exchange rate to price, invoice or convert amounts and must cite where it came from. Daily rates, not intraday; JSON, no model inference. Free sample at /api/fx-rates/sample.

Read URL content: extract the readable plain text and title of any public web page, with scripts, styles and navigation removed, plus character count, truncation flags and read time. Use this when an agent needs the text of an article, doc or product page to quote, classify or summarize, without an API key. Static HTML only (no JavaScript, no login), up to 20,000 characters, JSON out. For Markdown output use /api/web-read. Free sample at /api/url-text/sample.

Hash sha256, sha512, sha1 or md5, HMAC, JWT decode (header, payload, expiry, optional HS256 check), UUID v4, base64 encode and decode, URL parse, time zone convert and unix to ISO: one deterministic op per call. Use this when an agent needs a verifiable transform without shipping its own library. Pure Node, no upstream, no model inference, nothing stored, JSON out. Free sample at /api/dev-utils/sample.

Compare two strings literally, with no normalization and no inference: equality, lengths, and the first difference with line, column, Unicode code point and UTF-16 offset. Up to 20,000 UTF-16 units each. Use this when an agent must check that a delivered text matches the agreed text exactly, or locate where two versions diverge. Deterministic JSON. Free sample at /api/comparar-textos/sample.

Polymarket markets and prediction market odds: one page of public markets from the Gamma API (text and status filters, order by volume or liquidity, outcome prices) or a wallet's positions and activity from the Data API, with source URL and read time. Use this when an agent needs prediction-market odds, event lists or a trader's positions as evidence for a forecast or a report. JSON, no model inference. Free sample at /api/polymarket-markets/sample.

Summarize text with evidence: send 1 to 4,000 characters in English or Spanish and get a short summary plus 1 to 3 supporting quotes verified as exact substrings of your text, with a limitations note. Use this when an agent must condense an article, email or document and needs citations it can check before putting them in a report. Works only on the supplied text, no web retrieval, JSON out. Free sample at /api/source-bounded-summary/sample.

Argentina official gazette (Boletin Oficial) keyword search returning literal excerpts of matching notices with dates and source URLs; an optional date limits the search to that day's notices. Use this when an agent needs primary-source evidence of an Argentine regulation, decree, resolution or notice. No completeness guarantee and no legal interpretation; if the official search cannot be verified the call fails and is not settled. Free sample at /api/normativa-ar/sample.

Translate or adapt text of up to 6,000 characters into natural Spanish as spoken in Argentina and the Rio de la Plata (voseo), keeping names, numbers, links and formatting. Use this when an agent needs Spanish copy for Argentine or Uruguayan users, such as support replies, product listings, notifications or marketing, instead of neutral or European Spanish. Optional tone: formal, neutral or casual. Any input language; JSON output. Free sample at /api/translate-es/sample.

Match receipt claims to individual Base USDC Transfer logs in RPC records you supply. Returns unmatched or ambiguous claims, duplicate event counts and declared-wallet exclusions.

Formal letter in Argentine Spanish drafted from the facts you supply: claim, demand or request to a company or person, with sender, recipient, subject, facts, what you ask for and an optional response deadline in days. Use this when an agent must produce a firm, courteous letter for an Argentine consumer or business dispute. Returns the letter as text; it does not verify facts or give legal advice. Free sample at /api/cartas-ar/sample.

Argentine street address lookup: candidate matches from the official Georef API (street, number, locality, department, province, coordinates) with the source record, URL and read time; optional province id narrows the search.
