Check access before sending requests
Use your own InferGate key to request the live catalog. Account permissions, key restrictions and available balance still apply. A model listed here is not a guarantee of uninterrupted upstream service.
curl --fail-with-body https://api.useinfergate.com/v1/models \
-H "Authorization: Bearer $INFERGATE_API_KEY"Retired model requests return model_not_available. InferGate does not silently substitute another model. Keep keys on your server and out of browser bundles.
Prepaid usage and costs
API usage consumes available account credit. Review current input and output rates in application pricing before running a workload. This page does not promise free requests or a fixed discount. See how prepaid pricing works and compare actual usage logs after a small test.
