Use Case Recommendations
Best for: ApiPass
ApiPass is a unified model gateway that resells access to major AI models at a discount to official developer pricing, with one Bearer token covering chat, image, video, and music generation. The migration story is the pitch: it is drop-in compatible with existing official SDKs, so you swap the baseURL and the API key and your current request format, prompts, and client libraries keep working. Beyond that compatibility path there is a native shape where every model shares one predictable request schema — submit a generation task with a model name and inputs via a single POST, then either poll by task ID or receive a webhook when the result is ready — plus officially maintained typed SDKs so you skip the HTTP plumbing and auth headers. The catalogue spans 180+ models across brands including OpenAI, Anthropic, Google, Gemini, Veo, Kling, Runway, Flux, Suno, MiniMax, Qwen, ElevenLabs, and Nano Banana, billed per successful call with no subscription lock-in. Every model page carries a live 24-hour success-rate bar, which is a more honest form of uptime disclosure than most gateways offer, and every model is testable in-browser with 50 free signup credits before you write any integration code. The vendor states prompts and outputs are never stored, shared, or used for training.
Ideal use cases:
- •Teams or individuals who need one bearer token across 180+ chat, image, video, and music models
- •Teams or individuals who need drop-in compatible — change baseurl and key, keep your existing sdk code
- •Teams or individuals who need single consistent task schema with polling by task id or webhook delivery
- •Teams or individuals who need officially maintained, fully typed sdks
- •Anyone focused on llm api workflows
- •Anyone focused on model gateway workflows
Best for: CometAPI
CometAPI is an OpenAI-compatible gateway to more than 500 models across OpenAI, Anthropic, Google and the open-weight ecosystem, reached with one key and one base URL. Migration is a two-line change — point the OpenAI SDK's base_url at api.cometapi.com/v1 and swap the key — which is the whole pitch: no per-vendor SDK, no separate billing relationships, no vendor lock-in when a cheaper or better model appears. The catalogue spans modalities rather than only text, covering text-to-text, image-to-text, PDF-to-text, text-to-image and text-to-video, with per-model unit prices published openly next to each provider's official list price. The published discount is consistent at around 20% below official pricing — Claude Opus 5 at $4 per 1M against a $5 list, GPT 5.6 at $4 against $5, Gemini 3.6 Flash at $1.2 against $1.5, Claude Sonnet 5 at $1.6 against $2, and image and video models priced the same way, some per second rather than per token. The site claims over 10,000 active developers, sub-400ms average response time and 99.9% uptime, and it publishes direct comparisons against OpenRouter, Fal.ai, Replicate, Kie.ai and WaveSpeed rather than pretending competitors do not exist. A pricing calculator and model-versus-model comparison pages help before you commit. Signup includes test credits with no card, and the interface is localised into more than twenty languages — a genuine differentiator against the English-only gateways.
Ideal use cases:
- •Teams or individuals who need 500+ models behind one openai-compatible endpoint
- •Teams or individuals who need two-line migration from the openai sdk
- •Teams or individuals who need text, image, video, audio and pdf modalities
- •Teams or individuals who need per-model prices published against official list prices
- •Anyone focused on api workflows
- •Anyone focused on llm-gateway workflows
