Twotic

Twotic is a focused catalogue of production APIs. We build and operate every API here — nothing is resold. That means the documentation matches the implementation, the pricing has no middleman in it, and there is no upstream vendor who can change terms or disappear. Every API in the catalogue is built and operated by us — nothing here is resold. That means the documentation matches the implementation, the pricing has no middleman in it, and there is no upstream vendor who can change terms or disappear. What's in the catalogue today: • Web Extract — turn any URL into clean article text or Markdown, ready for a language model. No navigation, no scripts, no boilerplate. • Email Verify — check whether an address can actually receive mail: syntax, MX records, disposable providers, role accounts and likely typos. • Link Preview — unfurl any URL into the title, description, image and favicon needed to render a link card, with a fallback chain for every field. • Token Counter — estimate token counts and dollar cost across Claude, GPT, Gemini, Llama and Mistral before you make the call. • QR Codes — generate scannable QR codes as SVG, plus a ready-made WiFi join code with the payload escaped correctly. How it's priced Prepaid credit, spent per request. No subscription, no minimum, no invoice. Each API includes a free monthly allowance that is spent before your balance is touched. Because credit is prepaid, your balance is also your spending cap — you can never be billed for more than you have added. Failures on our side are refunded automatically at the moment they happen, not on request. Every response carries an X-Twotic-Cost header, so what you were charged is never a mystery. Built for agents, not just for people Every API is also a hosted MCP server. Point Claude, ChatGPT, Cursor or any MCP client at it and the endpoints become callable tools — connect with a one-click sign-in (OAuth 2.1) or an API key. Agent calls run through the same gateway as HTTP requests: same allowance, same price, same usage log, same automatic refunds. There is no agent tier and no markup. One key works across every API. The dashboard shows usage by API, endpoint and hour, with a request log and per-call cost. Full reference documentation, a metered playground you can run in the browser before you write any code, and long-form guides on the problems these APIs solve.
