CometAPI

What is CometAPI?

CometAPI is a unified AI API platform that lets developers call models from many providers through a single integration. Instead of managing separate accounts and keys for OpenAI, Anthropic, Google, xAI and others, you create one CometAPI key and send requests to an OpenAI-compatible endpoint. The company says the catalogue covers more than 500 models across chat, reasoning, image generation, video, speech and transcription.

CometAPI works as a reseller and router: you top up prepaid credits, and each request is billed at the model’s listed rate. The pricing page says every model is priced at least 20% below the provider’s official rate, and the homepage advertises savings of 20% to 40%. The company also claims 99.9% uptime, average latency under 400 milliseconds and more than 10,000 active developers, though these are its own figures. Its privacy policy says it does not store prompts or outputs, but it does not name a legal entity or registered address. When we checked in October 2026 the site, pricing page and documentation were all live.

Key Features

• One key for 500+ models: CometAPI gives you a single API key that reaches more than 500 models from providers including OpenAI, Anthropic, Google, xAI and DeepSeek. You switch models by changing the model name in the request rather than opening new vendor accounts.
• OpenAI-compatible endpoint: CometAPI accepts requests at api.cometapi.com/v1 in the same format as the OpenAI SDK. Existing code usually needs only a new base URL and key, which the documentation calls a drop-in replacement.
• Image and video generation: CometAPI routes image requests to models such as Nano Banana, GPT Image and Seedream. Its video endpoints cover Seedance, Sora, Veo and Kling for text-to-video, image-to-video and clip extension.
• Audio and speech models: CometAPI includes Whisper transcription, translation and text-to-speech models alongside its language models. Teams building voice features can keep speech, chat and media generation under one billing account.
• Usage and cost dashboard: CometAPI shows real-time usage analytics and spending in its dashboard. Developers can see which models consume the most credit and spot cost spikes before a monthly budget runs out.
• Prepaid credits that do not expire: CometAPI bills against prepaid credits with no monthly fee or minimum spend, according to its pricing page. Unused balances roll over indefinitely, which suits projects with irregular or seasonal traffic.
• Enterprise options: CometAPI offers custom enterprise pricing with volume discounts, a dedicated account manager and flexible service level agreements. Larger teams contact sales to arrange these terms instead of using self-serve top-ups.

Pros

• Lower listed prices: CometAPI lists every model at least 20% below the official provider rate on its pricing page. High-volume apps can cut their model bill noticeably without changing providers or rewriting prompts.
• Fast setup for existing code: CometAPI follows the OpenAI request format, so most apps switch over by changing two settings. A G2 reviewer praised the quick deployment and the ability to test several models through one API.
• Easy model comparison: CometAPI lets you run the same prompt against GPT, Claude, Gemini and Grok models from one account. That makes benchmarking quality and cost much faster than juggling separate keys and invoices.
• No subscription lock-in: CometAPI charges only for usage, with no monthly fee and credits that never expire. Small projects can start with free trial credits and pay nothing more until they actually need capacity.
• Prompt data not stored: CometAPI’s privacy policy states that it does not collect, store or record prompts, inputs or outputs. The homepage adds that user data is not used for model training, which eases some compliance concerns.

Cons

• Little company transparency: CometAPI’s privacy policy and refund policy name no legal entity, registered address or governing law. Businesses with vendor due diligence rules may struggle to approve it without further information from support.
• Non-refundable credits: CometAPI states that purchased credits are generally non-refundable, with exceptions reviewed case by case. Billing disputes must be raised within 30 days, so top up in small amounts until you trust the service.
• Extra dependency in the chain: CometAPI sits between your app and the original model provider, adding another party that can fail or change prices. Its own guide admits it is a weaker fit for teams committed to a single vendor’s native features.
• Few independent reviews: CometAPI had only two verified reviews on G2 and none on GetApp when we checked. Its uptime, latency and developer figures come from the company itself and lack third-party confirmation.
• Self-reported savings vary: CometAPI advertises discounts of 20% to 40%, but the examples on its pricing page show 20%. Actual savings depend on the model you call, so compare live rates before migrating heavy workloads.

Who is Using CometAPI?

• App developers: Building chatbots and agents across several model vendors.
• Startups: Cutting model costs with pay-as-you-go credits.
• Automation builders: Connecting models to n8n, Make.com and Dify workflows.
• Researchers: Benchmarking prompts across GPT, Claude and Gemini.

Pricing

CometAPI is pay-as-you-go with free trial credits at signup and no monthly fee (official pricing page, October 2026).

GetApp reports text models from $0.48 and image models from $0.008 per unit, but rates differ widely by model, so check the live price list.

Provider prices and CometAPI’s discounts both move often, so treat any figure here as a snapshot and confirm costs in your dashboard.

What Makes CometAPI Unique?

A single OpenAI-format endpoint that reaches text, image, video and audio models at prices set below the official vendor rates is the core of CometAPI’s appeal. OpenRouter and AIML API also aggregate models, but CometAPI puts its discount front and centre and extends the catalogue well into media generation, including Sora, Veo, Kling and Seedance video. The combination of prepaid credits that never expire and a stated policy of not storing prompts makes it a practical testing ground for developers comparing many models on a budget.

Compatibilities and Integrations

• API: REST endpoint at api.cometapi.com/v1 that follows the OpenAI SDK format.
• Models: GPT, Claude, Gemini, Grok, DeepSeek, Qwen, Sora, Veo, Kling and Whisper families.
• Tools: Documentation covers Dify, LobeChat, Open WebUI and 40+ other AI tools.
• Automation: Guides mention n8n and Make.com workflows for no-code pipelines.

CometAPI Tutorials

Getting a first response from CometAPI takes about five minutes.

1. Sign up at cometapi.com and claim the free trial credits.
2. Create an API key in the dashboard and store it as an environment variable.
3. Point your OpenAI SDK base URL to https://api.cometapi.com/v1.
4. Set the model name to the model you want and send a test request.
5. Watch the usage dashboard, then top up credits when the trial runs low.

How We Rated It

Summary

CometAPI suits developers and small teams who want to test and run many AI models from one account at below-list prices. Its main limitation is transparency, since the company does not publish a legal entity and most performance figures are self-reported. Larger businesses should ask for contract terms before relying on it in production. Start with the free trial credits, compare a few models on the same prompt, and keep top-ups small at first.
