# Calculer les tarifs

> Estimer le coût d’une charge utile d’utilisation précise pour un fournisseur, un modèle et un point de terminaison.

Calcule le tarif d’une charge utile d’utilisation selon les règles de tarification actives de la passerelle.

Fournissez :

* `provider` : identifiant du fournisseur, par exemple `openai`
* `model` : identifiant du modèle routé
* `endpoint` : famille de points de terminaison, par exemple `responses` ou `chat.completions`
* `usage` : l’objet d’utilisation à tarifer, comme le nombre de jetons ou d’autres données de mesure

Utilisez cette route si vous connaissez déjà le fournisseur, le modèle et le point de terminaison visés et souhaitez estimer le coût d’une utilisation précise. À l’inverse, `GET /pricing/models` répertorie les tarifs publics actuels du catalogue.
