Quickstart

Connect Claude Code to Faster Claude in about 60 seconds. Create an API key, pick your endpoint, set three environment variables, and keep your existing workflow.

Connect in about a minute. You change a few environment variables and your workflow stays exactly the same. Every session runs on Cursor Composer 2.5 (fast).

1. Get an API key

Create a key from your dashboard. Billing is pay-as-you-go, and you can reuse the same key across both endpoints.

Pricing is metered per token, with no subscription or seat fees:

Token type	Price per 1M tokens
Input	$0.50
Cache read	$0.20
Output	$2.50

2. Pick your endpoint

We run two entry points that reach the same engine. Choose the one closest to you:

Region	Base URL
United States (global default)	`https://api.fasterclaude.com`
Singapore (lower latency for Asia)	`https://api-sg.fasterclaude.com`

Both share your account, balance, and keys. The only difference is the base URL, so you can switch later by changing one line.

3. Point Claude Code at Faster Claude

Set the base URL, your key, and the model in your shell. Use the Singapore base URL instead if you picked that endpoint:

export ANTHROPIC_BASE_URL="https://api.fasterclaude.com"
export ANTHROPIC_API_KEY="fc-your-api-key"
export ANTHROPIC_MODEL="composer-2.5-fast"

composer-2.5-fast is the only model we serve, so this is the value to use. Persist these lines in your shell profile (~/.zshrc, ~/.bashrc) to make them permanent.

4. Run Claude Code as usual

Your sessions now run on Cursor Composer 2.5 (fast). Same commands, same editor integration, just faster and cheaper.

Troubleshooting

401 or auth errors. Check that ANTHROPIC_API_KEY is exported in the same shell that runs Claude Code.
Still hitting the old endpoint. Confirm ANTHROPIC_BASE_URL is set, then open a new terminal so the variable is picked up.
Slow first response from Asia. Switch ANTHROPIC_BASE_URL to the Singapore endpoint (https://api-sg.fasterclaude.com).
