create_bin

Create a new no-signup capture bin. Returns a live URL you can point any webhook, callback, or agent tool-callback at, plus a token to read what it captured. No account needed.

get_requests

Read the HTTP requests captured by a bin (method, path, query, headers, body), newest first. Set wait to block until a request arrives — ideal for 'trigger then assert' with no polling loop.

set_response

Configure the HTTP response a bin returns to whatever hits its URL — set a status code, content-type and body. Use it to test how your webhook sender / agent handles a 500, a specific JSON reply, etc.…

clear_bin

Delete all captured requests from a bin (the bin stays usable). Requires the bin token.
