CometAPI
Unified API for 500+ AI models at 20-40% savings
CometAPI delivers real savings (minimum 20% off) and convenience for teams juggling multiple AI providers. But verify your must-have models are available—Claude Fable 5 was removed due to upstream policy. Ideal for cost-conscious devs who value simplicity over absolute control.

Skip CometAPI if you need fine-tuning, on-premise deployment, a free tier, or exclusive access to a specific provider's latest model without intermediary risk.
Some niche models like Doubao-Seedance-2-0 only get a 10% discount instead of the standard 20-40%.
CometAPI is cheapest for teams using multiple providers: you save 20%+ on every model vs direct APIs. For single-provider needs, direct access may be simpler. Compared to OpenRouter, CometAPI undercuts by giving the discount upfront instead of charging a surcharge. Best for growing startups to mid-market teams; enterprises get custom volume discounts.
In short
CometAPI — Unified API for 500+ AI models at 20-40% savings. Best for SaaS developers embedding AI features without provider lock-in, Enterprise teams centralizing AI spend and model governance, AI automation builders using n8n, Make, or Zapier with one key. Free to use.

About CometAPI
CometAPI is a unified API platform that gives developers and enterprises access to 500+ AI models from OpenAI, Anthropic, Google, and others through a single API key. It permanently prices every model at least 20% below official rates, with savings up to 40%. The OpenAI-compatible endpoint enables drop-in integration with existing code, while sub-400ms latency and 99.9% uptime support production workloads. There are no monthly fees—you pay per use with credits that roll over indefinitely. Key features include a real-time usage dashboard with cost analytics, budget alerts, zero vendor lock-in (switch models in one line of code), and a built-in playground for prompt benchmarking. Recent additions include Kimi K2.7 Code, GLM-5.2 with 1M context, video models like HappyHorse 1.1 and Kling 3.0, and Doubao Seed models. CometAPI also offers SDKs, Postman collection, and n8n and Zapier integrations. The platform is designed for SaaS developers embedding AI features, enterprise teams centralizing AI spend, and automation builders using n8n or Zapier. Unlike direct vendor APIs, CometAPI eliminates multi-provider management and reduces costs without sacrificing performance. However, teams needing fine-tuning, on-premise deployment, or a free tier should look elsewhere.
Behind the Verdict
CometAPI is a solid choice for teams that need to access a broad range of AI models without managing multiple API keys or vendor relationships. The 20% minimum discount is straightforward and transparent—no hidden fees or tiered pricing games. The OpenAI-compatible endpoint means you can switch from a direct OpenAI integration to CometAPI with a single base URL change, which is a major time-saver. Where we'd reach for CometAPI: when you're building a SaaS product that needs to A/B test models from different providers, or when you want to consolidate AI spend across your organization into one invoice. The real-time dashboard and budget alerts are genuinely useful for cost control. The built-in playground is a nice bonus for prototyping. But it's not for everyone. Fine-tuning is not supported, so if you need to customize models, you'll need a direct provider relationship. CometAPI also doesn't offer a persistent free tier—only test credits on signup. Users who only need a single model (say, just GPT-5) may find CometAPI's extra abstraction unnecessary. Additionally, Claude Fable 5 was removed due to upstream policy, so availability can change. Compared to OpenRouter, CometAPI undercuts on price (OpenRouter adds a fee on top of official rates) and offers a wider model selection. However, OpenRouter has a larger community and more third-party tooling. For enterprise teams, CometAPI offers custom pricing and dedicated support, which can be a deciding factor.

Real-world workflow fit
Concrete scenarios for the personas CometAPI actually fits — and what changes day-one when you adopt it.
You're building a customer support chatbot and want to use GPT-5.6 for complex queries but Gemini 3.5 Flash for simple ones to save costs.
Outcome: Integrate once with CometAPI's OpenAI-compatible endpoint, then switch models in one line of code. Save 20% on every API call compared to direct billing.
Your team of 10 engineers uses multiple AI models across products, and you need a single invoice and per-team spend tracking.
Outcome: Create one CometAPI account, set budget alerts per team, and get a consolidated monthly invoice. Switch models without renegotiating contracts.
You build n8n workflows that use text and image generation, currently managing keys for OpenAI and Anthropic separately.
Outcome: Replace all keys with one CometAPI key in your n8n HTTP node. Access 500+ models and save 20% on every request.
Use Cases
- Build a chatbot that can switch between GPT-5.5, Claude, and Gemini based on task complexity.
- Run cost-sensitive inference workloads by routing to the cheapest model that meets quality thresholds.
- Prototype multimodal apps (text, image, video) without managing separate provider APIs.
- A/B test models side-by-side using the built-in playground to compare latency, cost, and output.
- Centralize AI spend across teams with per-team budgets and unified billing.
Models Under the Hood
as of 2026-07-06
Limitations
- CometAPI is an intermediary — you depend on their availability and routing.
- While they claim 99.9% uptime, any upstream provider outage can affect you.
- The 20-40% discount applies to most listed models, but some niche or very new models may have smaller discounts.
- No free tier beyond initial test credits.
- Legacy model deprecations require active migration to avoid service interruption.

Where the pricing makes sense
The company stage and team size where CometAPI's pricing actually pencils out — and where peers do it cheaper.
CometAPI is cheapest for teams using multiple providers: you save 20%+ on every model vs direct APIs. For single-provider needs, direct access may be simpler. Compared to OpenRouter, CometAPI undercuts by giving the discount upfront instead of charging a surcharge. Best for growing startups to mid-market teams; enterprises get custom volume discounts.
Setup time & first value
How long it actually takes to get something useful out of CometAPI — broken out by persona, not the marketing-page minute.
For most developers: sign up (2 minutes), get API key (instant), update base_url in your existing OpenAI SDK. First API call in under 10 minutes. Automation builders using n8n/Zapier: add CometAPI key as a credential and point HTTP nodes to the CometAPI base URL.
Switching to or from CometAPI
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From direct OpenAI/Anthropic/Google APIs: update base_url to https://api.cometapi.com/v1 and replace your API key — no code changes.
- →From OpenRouter: replace the API endpoint and key; CometAPI uses the same OpenAI-compatible format.
- →From a multi-key setup: consolidate all keys into one CometAPI key and update environment variables.
- ↗To direct provider API: update base_url back to the provider's endpoint and use the original API key.
- ↗To another aggregator: extract your model usage from CometAPI's dashboard and configure the new provider's API format.
