What this integration covers
| Capability | Scope |
|---|---|
| Client | Claude Code. Do not assume the same channel accepts arbitrary Anthropic SDK requests or other agents. |
| Gateway variable | ANTHROPIC_BASE_URL=https://api.superfastcode.com, without a /v1 suffix. |
| Credential | Superfastcode Claude/Anthropic-platform key in ANTHROPIC_AUTH_TOKEN. |
| Model selection | Use an available Claude model for the chosen key and channel. |
| Billing | Metered gateway usage; current rates and cache/context notes on Claude Code pricing. |
| Other Claude surfaces | This guide verifies the CLI flow. Desktop, cloud and editor-hosted sessions require separate client configuration and verification. |
The shortest verified setup path
- Install Claude Code and create a matching gateway key.
- Follow the macOS, Linux or Windows setup guide.
- Launch from the configured terminal, complete the test response, and inspect client status.
- Confirm the request in Console usage history, then persist your settings.
Use the client for this smoke test. Direct curl requests can behave differently on a client-restricted channel, so they do not replace a Claude Code test. A model listing or TCP connection alone is not enough.
Subscription and gateway billing are separate
A claude.ai subscription and a Superfastcode plan are different purchases. The gateway credential is active for these model calls; do not expect a personal Claude allowance to pay their gateway charges.
Within Superfastcode, API Credits represent metered service usage. The amount paid for a plan, the credits granted and the amount deducted per request are different quantities. Weekly reset rules, expiration and wallet availability are shown in the plan and Console. See the cost guide and calculator to estimate token charges without mixing cash and credits.
Compatibility, privacy and support
Claude Code evolves quickly. A successful text response does not verify every tool, model feature, background session or editor integration. Check the current client preset, use available models, and test representative tasks before adopting a new workflow.
Superfastcode is an independent third-party service operated by SuperfastAI LLC. Anthropic does not endorse, maintain or audit third-party gateways. Prompts, files, code, outputs and operational metadata may be processed to provide the service; read the Privacy Policy and Terms.
For support, send your client version, model, UTC time and a redacted request reference to support@superfastai.org. Never include a full API key.
