# SuperbAPI

> SuperbAPI is one prepaid wallet for every major AI model. You top up credit once, generate scoped API keys, and call text, code, image, video, and automation models through a single OpenAI-compatible endpoint. There is no subscription and no monthly minimum — each API call draws down your prepaid balance at that model's rate.

## What it is

- An AI API gateway and aggregator with one balance, one set of keys, and one base URL.
- A single OpenAI-compatible endpoint: point any OpenAI SDK at the SuperbAPI base URL and pass your key.
- Independent reseller/aggregator — not affiliated with, endorsed by, or partnered with any model owner. Third-party model names are used nominatively to indicate the model family a request routes to.

## Models

- 77 models are live and callable today on the gateway (one key, one balance).
- The catalog lists 157 models in total: the 77 callable models plus 80 more shown for comparison only (not callable via your key).
- Model families available include Anthropic Claude (Fable, Opus, Sonnet, Haiku), Google Gemini and Gemma, and a broad set of open-weight and frontier models from many providers.
- Availability, versions, routing, and pricing can change over time.

## Pricing

- Prepaid, pay-as-you-go. No subscription, no monthly minimum.
- US$5 in free credit for new verified users (one-time).
- Credit is valid for 12 months from purchase.
- Each API call draws down your balance at the model's per-token rate.
- Bonus, promotional, and free credits have no cash value and are non-refundable. Cash-paid credit may be refunded (unused portion) less a 6% payment-processing fee, at SuperbAPI's discretion.

## API surface

- Base URL: https://www.superbapi.com/v1 (OpenAI-compatible).
- Chat completions: POST /v1/chat/completions
- Models list: GET /v1/models
- Credit balance: GET /v1/credits
- Key info: GET /v1/key
- MCP endpoint: /mcp (Model Context Protocol over HTTP)
- Authentication: Bearer API key, generated in the workspace. Keys can be scoped to specific models and given a monthly budget cap.
- SSE streaming is supported on chat completions via stream: true.
- Model aliases: every model also answers to an "sb-" prefixed alias (e.g. sb-claude-fable-5). Use the alias in editors that reserve built-in model IDs (Cursor reserves all claude-* names); the gateway strips the prefix before routing, so pricing and behavior are identical.
