Legacy APIs weren’t built for AI agents.
Run AI agents reliably with our production runtime.
Everything AI agents need to use APIs in production: authentication, retries, idempotency, auditability, policies, and more.
Why Swytchcode
Legacy APIs and AI agents don’t blend.
Swytchcode gives agents the implementation knowledge these APIs never documented, then governs every action that runs.
Which version? Which combination?
One API can carry years of versions, and a single operation can accept more valid field combinations than anyone documented. Your agent has no way to know which one your workflow needs.
200 OK. Body says failed.
The call returned success. The body carried an error. Your agent logged a win. The action never happened.
No allowlist. No dry run. No undo.
A destructive call runs against production instead of test. Nothing stops it mid-flight, and nothing records what happened.
How it is used
Agents call Swytchcode. Swytchcode calls the APIs.
The CLI is the execution layer before any legacy or SaaS API call leaves your environment.

How it works
How Swytchcode makes a legacy API usable by an agent.
Read the docs[00]
Your agent calls an API it has never seen. We make sure it goes through.
Missing context, expired tokens, and undocumented changes break agents silently. Swytchcode catches all of it before the call goes out.
