Vendor directory

Does this vendor refuse a repeated request?

An idempotency key only helps if the vendor on the other end honours it. Many do not, and almost none say so on the page you are reading when you decide. This is the list. It is free, needs no account, and is the same data our own gate uses.

Where a vendor deduplicates, Ratchet can derive the key it will deduplicate on, and at-most-once initiation becomes at-most-once execution at that vendor — enforced by them, not by your agent's good manners. How that works.

Not the list you wanted?

This page is about services your agent acts on — where the money moves or the message sends. If you are looking for where your agent runs — Claude Code, Cursor, LangChain, n8n, a model provider — that is Works with, which lists 90 of them.

A vendor missing here is not a vendor Ratchet cannot gate. The gate works with anything you can call; this directory only records which vendors add enforcement of their own. Ask for one at hello@ratchetgate.com.
