Celedog vs Calling Provider APIs Directly

Calling OpenAI / Anthropic / Google directly works fine — until you need more than one. At that point, the integration debt compounds. Here's what you trade off.

Should you call OpenAI, Anthropic and Google directly, or route through a gateway like Celedog? Calling one provider directly is perfectly fine. The trade-off compounds the moment you need a second, a third, and a finance team that can read the bill.

Direct integration: simple until it isn't

One provider, one SDK, one key, one invoice — direct is the least moving parts. For a single-model prototype it is the right call. The cost shows up later: every new provider is a new SDK, a new auth scheme (Bearer vs x-api-key vs SigV4 vs OAuth), a new billing account, and a new invoice to reconcile. Failover, cost routing and a unified usage log are all things you now build and maintain yourself.

Where the gateway pays off

A gateway like Celedog collapses N integrations into one OpenAI-compatible endpoint. Adding a model becomes a string change, not an engineering project. Billing becomes one wallet instead of N invoices. Failover and auto-routing are built in. And for teams in China or Indonesia, you can actually pay — in your own currency, with local rails — instead of wrestling a USD-only card flow at every vendor.

The honest costs of a gateway

A gateway adds one network hop (single-digit milliseconds, dwarfed by model latency) and a dependency you do not control. Mitigate the latter by choosing a gateway that speaks the standard OpenAI API, so your exit cost is a base-URL change — never a rewrite. Celedog is deliberately a drop-in OpenAI endpoint for exactly this reason: low switching cost both in and out.

One provider forever? Go direct. More than one — now or soon — and a gateway pays for its one network hop many times over. Retrofitting a gateway after hard-coding a provider everywhere is the expensive path.
