The catalogue is free. The credentials are not.

Reading every schema, comparing every provider and calling with a key you already have cost nothing and are not a trial. What the plan buys is the other lane: calls we make on your behalf, with credentials you never had to register for.

Where the gate is, and why there

Making a call work is the part worth proving, so it is free. Making it work without you holding an account at the other end is the part with a real cost behind it, and that is the part that is paid. Anything else would be charging for the step before the one worth paying for.

Allowance first, then the wallet

A plan includes a monthly allowance of brokered calls. Past it, calls come out of the token wallet at a rate that reflects what the vendor charges us, which is what stops a modest subscription becoming an unbounded bill in either direction.

Questions

Do I have to bring my own API keys?

You can, and that lane is free for ever — pass your key on the request or store it against your account, and we are one proxy hop. The paid lane is the other direction: we call 226 providers with our credentials so you never register anywhere. Both go through the same client and the same operation names.

What does a call cost?

Browsing everything here and calling with your own key cost nothing. Calls through our credentials come out of your plan allowance and then out of the token wallet, charged per operation with the vendor cost recorded alongside so the price is not a guess.

Is every call metered?

Yes, and deliberately so: every path — HTTP, the MCP server, a chatbot function call, a workflow step — goes through one pipeline that charges before it executes. This engine once ran entirely unmetered, which is free compute with a price list on it, and a test now asserts there is no route around the meter.
