Payloda API docs

Interactive documentation for every Payloda API: endpoints, parameters, a live request builder and example responses. Everything is a GET request that returns JSON, so it's easy to try from a browser, curl, or an LLM agent.

How auth works: requests are made through your Payloda plan on the Zyla marketplace, which supplies your base URL and injects your API key, so the paths and parameters in each reference are identical regardless of plan.
