SilkRouter
Opening the site...
SilkRouter uses prepaid balance as the operating boundary for AI API traffic, helping teams fund usage before requests scale.
Prepaid credits make AI spend easier to understand: add funds, route requests, monitor balance, and replenish intentionally.
Postpaid provider billing can surprise small teams when traffic spikes. Prepaid balance gives founders and agencies a clearer budget boundary.
Fund before use
Monitor burn by workflow
Separate keys for projects
Combine credits with routing and spend limits
Confirm SDK behavior, base URL setup, model IDs, streaming, and error handling before moving production traffic.
Check how API keys, balance, request logs, low-balance behavior, and offboarding work after launch.
Make sure the usage view answers finance, support, agency, or customer questions without rebuilding data manually.
Use these answers to decide what to test, what to keep, and what not to assume before moving production traffic.
They help cap funded exposure, but you still need server-side enforcement, monitoring, limits, and prompt discipline.
Show balance, billed usage, request status, limits, and helpful summaries.
Start with Startup launches and Agency client budgets, then review usage before expanding routing rules.
