Billing and credits | Respan Docs

Every Gateway request authenticates to Respan with a Respan API key. The Gateway supports two funding paths for access to the upstream model:

Funding path	How it works	Start here
Respan credits	Add a Gateway balance and let Respan use that balance for supported model traffic.	Billing
Bring your own key (BYOK)	Connect credentials from your own model-provider account.	Provider keys

Model and credential availability can vary. Use the current Models page and provider settings to confirm the path available for the model you want to call.

Open Billing

Go to Settings → Billing. The page separates billing into three tabs:

Gateway shows your Gateway balance and credit controls.
Observability contains the separate observability billing area.
Billing details contains billing information and invoices.

Billing page with Gateway, Observability, and Billing details tabs.

Add Gateway credits

Open the Gateway tab

On the Billing page, select Gateway.

Choose an amount

Select Add credits, then choose a preset amount or Other.

Review auto reload

If you want to replenish the balance automatically, enable auto reload and review the displayed reload amount and threshold.

Confirm the purchase

Review the amount and settings, then select Add credits in the dialog.

Add credits dialog with amount choices and optional auto reload.

Unused credits expire 12 months after purchase. Review the current disclosure in the Add credits dialog before confirming.

Manage balance controls

The Gateway tab also exposes these controls:

Auto reload replenishes the balance using the amount and threshold shown in its configuration.
Low balance warning threshold controls when Respan warns you about a low Gateway balance.

Review these values after changing how your application uses the Gateway.

Use a provider key instead

BYOK connects Respan to credentials from your own provider account. Go to Settings → Providers, select a provider, and add the required credential fields.

See Provider keys for stored, request-scoped, load-balanced, and per-model credential options.
