Talk to a person
TariffMonkee is solo-operated by Jeff Anderson. Email goes to him, not a ticket queue. Expect a reply within one to two business days (Taiwan time zone, UTC+8).
Support
Problems with a paid call, unexpected errors, or billing questions. Include the endpoint, timestamp, and transaction details so it can be traced fast.
Everything else
Integration questions, partnership or listing inquiries, endpoint requests, press.
Building an agent?
You may not need to email at all: full machine-readable docs live at /docs, site orientation at /llms.txt, and crawler policy at /robots.txt. If your agent can read a 402 response, it already knows how to pay.
