Pay only when AI costs go down.
Connect your own provider key. LangSwap compares only the models you approve, routes each request to the lowest quoted cost and charges 25% only from positive estimated savings.
Your provider account
BYOK means the model provider bills you directly. LangSwap never finances your requests or stores the provider key.
Measured savings
Every request receives a server quote, an approved-model route and an auditable receipt based on actual provider usage.
Outcome-based fee
LangSwap charges 25% of positive estimated savings. Zero or negative savings means a zero LangSwap fee.
