Claude Standard
StartupAPI Standard traffic is routed through Kiro via PayGo.
This is our lower-cost routing path for supported Claude models.

Understand how billing works
Prepaid StartupAPI credits fund billable model usage; reservation and settlement behavior depends on whether usage was delivered.
How billing works
- Credits are prepaid — you're never billed by surprise.
- Uncached input, cache writes, cache reads, and output use separate production weights and rates.
- A failure before billable usage releases the temporary reservation without a usage charge.
- A successful response or partial delivered stream settles the usage delivered. An ambiguous no-usage stream can enter settlement review.
Current models and rates
The live Models/Pricing page is the source of truth for enabled identifiers, model-specific context and output limits, Standard and Max pricing, and cache-read/write rates.
