Zyla API Hub MCP: find and call thousands of APIs from your AI app

How to add Zyla API Hub to Claude, ChatGPT or Cursor

1. 1Click Connect Zyla API Hub free. There's no sign-in, so its tools are ready at once.
2. 2`search_catalog`, `browse_catalog`, `list_categories` and `get_api_info` only look. `call_api` is billed per successful call to a card on file, and `register` and `get_payment_url` set up an account and payment, so switch those off if your AI app should only research APIs.
3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
4. 4Ask your AI app to find a currency rates API on Zyla and tell you its price per call, then open Activity to see the `search_catalog` and `get_api_info` calls.

Finding and calling APIs from Claude or Cursor

• Search the catalog for live data your AI app doesn't have, such as flight status, weather or currency rates, with `search_catalog`.
• Check an API's price per successful call and average latency with `get_api_info`.
• Call an endpoint with `call_api`, paying only for successful (2xx) responses.
• Check your plan, call count and spend this billing cycle with `account_status`.

Keep pay-per-call spending in view

• Switch off `call_api`, and your AI app can browse APIs but not run up charges.
• Set a policy to warn before any `call_api` request goes out.
• Activity records every Zyla call, so you can match charges to the requests behind them.
