More in the full FAQ.
Does Claude Code work?
Yes. Set ANTHROPIC_BASE_URL to https://api.topbilling.in, ANTHROPIC_AUTH_TOKEN to your Top Billing key and ANTHROPIC_MODEL to a model ID from the Models page. The Claude Code guide has the details.
Is there a quicker way to set up Claude Code?
Yes. Run npx @topbilling/cli claude and it writes the Claude Code settings for you. See Set up your tools.
Why is my model missing from Claude Code’s /model picker?
Claude Code’s gateway model discovery only lists IDs containing claude or anthropic, and Top Billing model IDs are neutral (tb-…). Set ANTHROPIC_MODEL to the model ID explicitly.
Can I see what a Claude Code session cost?
Yes. Every Claude Code request is billed like any other API request and shows up in Usage with its session id.
Can I use my claude.ai login with Top Billing?
No. Use a Top Billing key (tb_…). The gateway rejects credentials that are not Top Billing keys with a 401 and never forwards them.
How do I pay?
Add credits on the Billing page with UPI, cards or net banking through Cashfree, our payment gateway. Card, UPI and bank details are entered with the gateway and never reach our servers.
Do I get a GST invoice?
Yes. GST is shown before you pay, and a tax invoice carrying our GSTIN is on the Billing page after every successful payment.
