About

Twotic builds and operates every API in its catalogue. Nothing here is resold, so the documentation matches the implementation and the pricing has no middleman in it.

Why it exists

Most API directories optimise for breadth. The result is thousands of listings whose documentation is a stale screenshot, whose uptime is unknown, and whose pricing only becomes clear after you have integrated. Finding an API is easy; trusting one is not.

We took the opposite position: a small number of APIs, each one built and run by us, documented properly, priced transparently per request, and metered through a gateway that reports exactly what a call cost on the response itself.

Because we operate them, the documentation cannot drift from the implementation, and there is no third party who can change terms, raise prices or disappear.

How it works

One key works across every API. Requests go through our gateway, which authenticates, rate limits, meters and serves them. Credit is prepaid, so you can never be billed for more than you have already added, and a call that fails on our side is never charged.

Built for agents too

Every API publishes a Model Context Protocol server, with tool descriptions written for a model choosing between options rather than lifted from the developer docs. Agent calls run through the same gateway, priced identically, with no separate tier.
