Agent Quota Gateway

One agent burnout shouldn't stop the pipeline.

Auto-rotate accounts. Keep shipping.

View on GitHub

A lightweight proxy that sits between your Claude Code sessions and the Anthropic API. It owns your credentials, auto-rotates between accounts when one hits its quota limit, and exposes a single local endpoint your tools point at.

The problem

A 5-hour quota window runs out mid-session. Your agent stalls with a 429. You manually swap credentials or wait. If you run multiple accounts, you repeat this across every burnout.

Agent Quota Gateway handles the rotation transparently.

How it works

You declare named pools — groups of interchangeable accounts. Your tools point at the gateway and send a pool name instead of a real token. The gateway picks a backend, swaps in the real credential, and forwards the request. On a 429, it switches to the next healthy account and tells your client to retry — no session lost.

Key features

  • Auto-rotation — switches accounts on a real 429, transparent to the client
  • Sticky routing — stays on one account per pool to preserve prompt cache
  • Pool health API — inspect quota and member status at /_gateway/quota and /_gateway/pool
  • Multi-vendor — native Claude subscriptions, API keys, and compatible vendors (Z.ai, MiniMaxi, Volcengine Ark)
  • Zero probing — no synthetic test requests; quota state is read from real response headers

Source-available & self-hostable

The free core is source-available under the Business Source License 1.1 (BSL 1.1). You can read the source, build it, and self-host it. This is not permissive open source (not MIT/Apache) — the BSL sets the terms under which you may use it.

Additional commercial capabilities ship as part of the paid My AI Team bundle.

Requires Go. No Docker image — go build is the deliverable:

git clone https://github.com/SHUKE-LABS/agent-quota-gateway
cd agent-quota-gateway
go build -o agent-quota-gateway ./cmd/agent-quota-gateway
