Frequently asked questions

What is a credit?

A credit is the unit of usage on Stewrd. Each API request costs credits based on which capabilities are used. Chat and Data cost 1 credit each. Files cost 2 credits. Research and Code cost 3 credits each. Documents cost 5 credits. A request using multiple capabilities costs the sum of their weights.

Do credits expire?

Free credits replenish monthly (200/mo). Purchased credits never expire — use them whenever you need them.

What do free accounts get?

Every account gets 200 free credits per month, automatically replenished. Free credits include Chat and Data capabilities. Purchase any credit pack to unlock all 6 capabilities.

How is usage calculated for streaming responses?

A streaming response costs the same credits as a non-streaming response. Credit cost is determined by the capabilities used, not the response format or duration.

What capabilities are included with purchased credits?

All 6 capabilities: Chat (1 credit), Data (1 credit), Files (2 credits), Research (3 credits), Code (3 credits), and Documents (5 credits). Free accounts are limited to Chat and Data.

What happens when I run out of credits?

API calls return a 402 status code. Buy a credit pack to continue immediately — credits are added to your balance instantly.

How long are generated files available?

File URLs expire after 24 hours by default. Files are served via signed URLs from Cloudflare R2.

What is BYOK (Bring Your Own Key)?

Stewrd is infrastructure for AI agents — orchestration, tool execution, file storage, and sandboxing. You bring your own LLM API key (OpenAI or OpenRouter) so you control model choice and costs. Your key handles the thinking, Stewrd handles the doing. Your key is encrypted at rest and never logged.

Can I use the API for commercial projects?

Yes. All accounts, including free, allow commercial use. There are no restrictions on what you build with the API.
