Plans and pricing
Gateway charges for the model traffic it routes: vendor token cost plus Merge’s fee, with no seat fee or minimum.
Plans
Signup credit expires 12 months after signup. Amounts and the free model list are on the pricing page. Adding a card in Billing settings moves you to Pro: the full model catalog, no daily cap.
What one request costs
Every response carries usage.cost, the model cost in USD (your contract price if you have committed spend). With include_routing_metadata: true, routing.merge_fee_usd adds Merge’s fee; the two sum to the request’s bill. Web search is billed separately (per-call cost).
Bringing your own vendor key
On a BYOK key, your vendor bills you for the tokens and your Merge invoice carries only the fee.
When credit or plan limits are reached
Each block happens before any vendor call, so it costs nothing.
To cap spend below your balance, use Budgets.
