- Base URL: https://rockapi.ai/v1
- Streaming supported for all models
- Cached token pricing supported
- Prepaid balance billing (no monthly fees, no minimums)
- Setup time: under 2 minutes

## Pricing Examples

| Model | Direct Price (input/1M) | Rock API Price (input/1M) | Savings |
|-------|------------------------|--------------------------|---------|
| Claude Sonnet 4.6 | $3.00 | $2.10 | 30% |
