Every API, one token.
Pick an API to see the request, the JSON it returns, and the limits.
Why LiveAPI
A toolbox for the facts a product keeps needing.
Signup, checkout and support all ask for the same kinds of facts: where a request came from, whether a phone or email is well formed, which country and postal code apply, what the official exchange rate is, and whether an ID's check digit holds. LiveAPI keeps those calls in one toolbox, so a new field does not mean a new vendor.
One key for the whole set
IP location, countries, phones, postal codes, national IDs, rates, holidays, time zones and the rest share one bearer token, one balance and one docs site.
A record you can keep
A successful call returns JSON you can put into a form, a checkout or a log line. Only 2xx responses use a call. Errors are free.
Apps and agents, same balance
REST and the MCP server at liveapi.io/mcp spend the same key. Pack calls never expire. Unlimited is a monthly flat rate when you want one.
