CometAPI
One OpenAI-compatible API key for 500+ AI models at 20% below official provider rates
If AI spend is the line item you keep defending, CometAPI is the aggregator we'd test first. The 20% discount is printed on the pricing page rather than negotiated, applies per-token for text and per image or second for media, and carries no monthly fee. The catch is that you inherit their catalog decisions — deprecation notices land on you to handle.

Skip CometAPI if you need fine-tuning, custom weights or on-premise inference, or if you are uncomfortable putting an intermediary in the request path of production traffic.
Model retirements carry no automatic migration — when older OpenAI models shut down on October 23, 2026 or the Sora series was pulled on 2026-09-29, moving to a replacement model is work you absorb.
Pay-as-you-go credits with no subscription and no minimum spend put CometAPI in reach of a solo developer, while the published 0.8x multiplier on official models keeps it below pass-through aggregators such as OpenRouter, which charge official rates plus a credit-purchase fee. Team and enterprise budgets see the bigger swing: volume discounts, per-team spend governance, custom SLAs and dedicated servers are negotiated rather than listed.
In short
CometAPI — One OpenAI-compatible API key for 500+ AI models at 20% below official provider rates. Best for SaaS teams embedding AI features who want 20%+ off every call without rewriting code, Enterprises consolidating multi-provider AI spend under one account with per-team budgets, Automation builders wiring models into n8n, Dify, Coze or Zapier who need a single credential.

About CometAPI
CometAPI collapses OpenAI, Anthropic, Google and a dozen other providers into a single API key pointed at https://api.cometapi.com/v1. Existing OpenAI SDK code keeps working after a base_url swap, and one credential covers 500+ models across Chat Completions, Responses, Anthropic Messages, Image, Video and Audio formats. The catalog runs current: Gemini 4 Argon, Claude Haiku 5.5, DeepSeek V4.1 Flash, GPT-6 Luna, Kling 4.0 and Vidu Q4 Preview all sit under the same key. The pricing model is published instead of quoted. Official models bill at the provider rate times 0.8 — Claude Haiku 5.5 at $0.08 per 1M tokens against $0.1, Qwen-Image-3.0 at $0.024 per image against $0.03, Wan 3.0 Prime at $0.0544 per second against $0.068. Specialty models bill per image, per second or per clip at the endpoint's own unit rate. Pay-as-you-go credits, no monthly fee, no minimum spend, and unused balance carries forward. Who it suits: SaaS teams embedding AI features who don't want five provider accounts and five invoices, enterprises consolidating multi-provider spend with per-team budgets, and automation builders wiring models into n8n, Dify, Coze or Zapier. Supporting pieces include a real-time usage dashboard for spend, latency and call volume, budget alerts, a budget estimator, side-by-side model comparison, a playground, a Postman collection and sample projects. The tradeoff is that CometAPI sits in the middle: no fine-tuning, no on-prem deployment, and catalog churn is real — Sora video models were pulled, older OpenAI snapshots retire on fixed dates, and doubao-seedream-5-0-260128 shuts down 2026-11-24 with no automatic migration. Against OpenRouter, which passes official rates through plus a credit-purchase fee, CometAPI discounts every official call.
Behind the Verdict
The case for CometAPI is arithmetic. Every official model is priced at 0.8× the provider rate, listed line by line on the pricing page. Run 50M Claude Haiku 5.5 tokens a month and the delta against buying direct is visible on one invoice instead of four. We'd pick it when the job is breadth plus consolidation. Teams that need reasoning from Claude, images from Qwen-Image-3.0 or Nano Banana 2.1, video from Kling 4.0 and real-time voice from GPT-Realtime-2 in the same product get one key, one bill and built-in failover instead of hand-rolled retry logic. The migration path is genuinely short — change the base_url, keep the SDK. That makes it a cheap experiment: point one service at it, compare the invoice and the latency numbers on the dashboard, then decide. Where it bites is continuity. CometAPI publishes shutdown dates, not migration assistance. doubao-seedream-5-0-260128 goes dark on 2026-11-24 and the changelog names seedream-5-0-pro-260628 as the replacement — but nothing rewrites your code. Five OpenAI snapshots retire 2027-01-14 with gpt-6.1-sol and gpt-6-luna suggested. If you pin model strings and forget them, you find out in production. Pass if you need fine-tuning, custom weights or air-gapped inference. Pass too if a compliance review can't tolerate a hop between your app and the model provider, or if a niche model is central to your product and isn't onboarded. Closest alternative is OpenRouter. Both give one key across many providers; OpenRouter charges official rates plus a credit fee where CometAPI discounts. If you want the cheapest per-call number and don't mind the middleman, this is the one to price-check.

Real-world workflow fit
Concrete scenarios for the personas CometAPI actually fits — and what changes day-one when you adopt it.
You already call the OpenAI SDK in production. You create a CometAPI account, copy the API key, change base_url to https://api.cometapi.com/v1 and pick a model name from the catalog.
Outcome: The first call runs against CometAPI without a code rewrite, and the dashboard starts showing spend, latency and call volume for every request.
Five teams each hold their own OpenAI, Anthropic and Google accounts. You move them onto one CometAPI credential, set per-team budgets on the Enterprise plan and watch the unified usage table.
Outcome: One invoice replaces five, and budget alerts fire before a team overspends instead of at month-end reconciliation.
You build in n8n and need text, image and video in one flow. You wire the single CometAPI credential into n8n and call Nano Banana 2.1 for images and Kling 3.0 Turbo for video.
Outcome: One credential and one balance cover all three modalities, and the budget estimator lets you size the monthly credit before the first run.
Use Cases
- Build a chatbot that switches between GPT-6.1 Sol, Claude Sonnet 5.5 and Gemini 4 Pro by task complexity.
- Route cost-sensitive inference to the cheapest model that clears your quality threshold without re-plumbing credentials.
- Prototype multimodal apps spanning text, image and video without opening separate provider accounts.
- Benchmark prompts across models in the built-in playground to compare latency, cost and output side by side.
- Centralize AI spend across teams with per-team budgets and one consolidated invoice.
- Generate images with Grok-Imagine-Image-2.0 at $0.032 per image against $0.04 official.
- Produce video with Kling 3.0 Turbo text-to-video and image-to-video endpoints.
- Wire one CometAPI credential into n8n, Dify, Coze or Zapier automation flows.
Models Under the Hood
as of 2026-10-16
Limitations
- Pricing follows a published framework rather than one flat rate: official models are billed per token at the official rate times 0.8, while specialty models are billed per image, clip, second or character, so cost per call varies a lot by endpoint and model type.
- Model availability is upstream-dependent and subject to retirement: the changelog lists gpt-3.5-turbo-0125, gpt-4-0613, gpt-4-1106-preview, gpt-4-turbo, gpt-4o-2024-05-13, gpt-image-1, o1-2024-12-17 and o1-pro-2025-03-19 shutting down on October 23, 2026 with no automatic migration, and all Sora video models were removed on 2026-09-29.
- Some catalog entries carry a 'Coming soon' label rather than immediate availability, including Claude Fable 5.5 and Gemini 4 Argon.
- There is no fine-tuning, no custom model hosting and no on-prem or air-gapped deployment, and because CometAPI sits between your app and the provider, your effective uptime depends on both.

Free Trial
$0
Ideal for
Developers and evaluation teams who want to test the OpenAI-compatible endpoint and browse the 500+ model catalog before committing any budget.
What this tier adds
Free entry point: instant test credits at signup with no credit card required, plus playground and catalog access.
Pay-as-you-go
Per-use credits
Ideal for
SaaS teams and solo builders running production traffic who want at least 20% off official rates without a monthly commitment.
What this tier adds
Adds real production billing on credits — every official model at 0.8x official rate, no monthly fee, no minimum spend, unused credit carries forward, one consolidated invoice, dashboard, budget alerts and failover routing.
Enterprise
Custom
Ideal for
Enterprises consolidating multi-provider AI spend across several teams that need governance, volume pricing and contractual guarantees.
What this tier adds
Adds negotiated volume discounts, per-team budgets and spend governance, custom SLAs with a dedicated account manager, unlimited RPM and TPM, dedicated servers, extended data storage, full staff training and integration support.
Where the pricing makes sense
The company stage and team size where CometAPI's pricing actually pencils out — and where peers do it cheaper.
Pay-as-you-go credits with no subscription and no minimum spend put CometAPI in reach of a solo developer, while the published 0.8x multiplier on official models keeps it below pass-through aggregators such as OpenRouter, which charge official rates plus a credit-purchase fee. Team and enterprise budgets see the bigger swing: volume discounts, per-team spend governance, custom SLAs and dedicated servers are negotiated rather than listed.
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.
Sign-up to first successful call is minutes for a developer: no credit card is required for test credits, you copy one key, and you change base_url in code you already have. Wiring the same key into n8n, Dify, Coze or Zapier is a single credential entry. An enterprise consolidation across multiple teams takes longer because of per-team budget and governance setup.
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 OpenAI direct: change base_url to https://api.cometapi.com/v1 and keep your existing SDK call, since the Chat Completions format is preserved.
- →From Anthropic direct: point Claude calls at the Anthropic Messages API format CometAPI exposes, then check the model ID against the catalog.
- →From OpenRouter: swap the base_url and key; CometAPI bills official models at 0.8x rather than official rate plus a credit-purchase fee.
- →From a multi-vendor setup: replace each provider key with the single CometAPI credential and fold the separate bills into one invoice.
- →From a retired model: check the changelog's replacement column before migrating, because shutdowns happen with no automatic migration.
- ↗To direct provider accounts: restore the original base_url and key per vendor, at the cost of returning to official list pricing.
- ↗To OpenRouter: change base_url and key, accepting pass-through official rates plus a credit-purchase fee.
- ↗To self-hosted inference: not a base_url change — you would rebuild the serving layer, since CometAPI does not expose weights or an on-prem option.
