## CometAPI

CometAPI is an aggregation layer for large language and multimodal model providers. Instead of maintaining separate accounts, keys and billing relationships with OpenAI, Anthropic, Google and a growing set of image, audio and video vendors, teams sign up once, get a single API key, and call any of 500+ models through an OpenAI-compatible base URL. Existing SDK code usually works after changing the base URL and model name, which keeps migration effort low.

The commercial pitch is straightforward: pay-as-you-go credits, line-item pricing for every model, and rates set below official vendor pricing, with the platform advertising ongoing savings of roughly 20 to 40 percent. There is no monthly subscription or minimum spend, unused credits carry forward, and the model catalog is searchable with side-by-side pricing and capability comparisons. Because model names are the only thing that changes when you switch vendors, teams gain portability if a provider raises prices or has an outage.

Operationally, CometAPI positions itself as production infrastructure rather than a demo playground. It advertises 99.9% service availability and average latency under 400 ms, exposes an API status page and benchmarks, and offers a dashboard for spend, latency and call volume with budget alerts. Enterprise-oriented features include centralized accounts for multiple teams, per-team budgets, encrypted transit and a stated policy that customer data is not used to train models. Integrations with coding agents, low-code automation platforms and app builders let teams plug the gateway into existing workflows rather than rebuilding them.

**Pricing & Plans:** Pay-as-you-go API credits with no monthly subscription, minimum spend or credit card required at signup. CometAPI advertises per-model rates below official vendor pricing, typically 20-40% cheaper, and test credits are included when you create an account.

- **One key for 500+ models:** Replace separate OpenAI, Anthropic and Google credentials with a single key and switch models by changing one line of code.
- **OpenAI-compatible endpoint:** Route text, reasoning, coding, image, audio and video workloads through one OpenAI-compatible base URL without rewriting your app.
- **Transparent pricing and savings:** Line-item pricing per model with discounts below official vendor rates, pay-as-you-go with no monthly subscription or minimum spend.
- **Usage analytics and cost control:** A real-time dashboard tracks spend, latency and call volume so you can set budget alerts and compare models side by side.
- **Prebuilt tool integrations:** Works with Claude Code, Codex, Cline, Dify, n8n, Zapier, Coze and other agent, automation and app-building tools.

**Strengths:** One credential and one endpoint for 500+ models from many providers; OpenAI-compatible format means existing code keeps working with minimal changes; Pay-as-you-go credits with no monthly fee and unused balance carried forward; Dashboard for spend, latency and call volume with budget alerts

**Limitations:** You depend on a third-party intermediary for uptime and latency on every routed model; Some catalog entries are marked coming soon, so not every listed model is instantly available; Pricing and availability can shift as upstream vendors change their own rates

## Kaopu API

Kaopu API positions itself as "AI application infrastructure foundation" — a single gateway that sits between your application and the many large language models you want to use. Instead of wiring up a separate integration and billing account for every provider, you connect your API keys as channels, and Kaopu API exposes them through one standard, OpenAI-compatible protocol. The marketing highlights high-concurrency handling with automatic load balancing, so traffic can be spread across channels to keep services responsive.

Beyond routing, the platform doubles as an administration dashboard. You can configure channels, set access permissions, and run multi-user management with flexible roles from one central panel — useful when several developers or teams share the same infrastructure and need their usage and access kept separate. Billing is pay-as-you-go, with real-time usage monitoring and transparent cost tracking so you can see exactly where tokens and budget are being consumed.

Kaopu API is built on the open-source New API project, which means the gateway is self-hostable and extensible. Setup follows three straightforward steps: configure your keys and channels, connect through the compatible OpenAI, Claude, or Gemini routes, then monitor usage, costs, and performance with real-time analytics. Because it is a gateway rather than a model provider, its practical value comes from the upstream services you choose to connect.

**Pricing & Plans:** Pay-as-you-go model with real-time usage monitoring and transparent token-based billing inside the dashboard; since it is self-hostable, total cost also depends on the upstream providers you connect. Public per-token rates are not published on the site.

- **Single unified API endpoint:** Route requests to many upstream AI models through one standard, OpenAI-compatible API protocol, so your code stays the same as providers change.
- **Automatic load balancing:** High-concurrency handling with automatic load balancing spreads traffic across your configured channels to keep responses reliable.
- **Transparent token billing:** Pay-as-you-go accounting with real-time usage monitoring and clear per-key, per-model spending so you always know where budget goes.
- **Multi-user admin dashboard:** Add API keys, set up channels, and assign access permissions for multiple users from one central admin panel.
- **Open-source and extensible:** One-click configuration that adapts to the New API multi-protocol setup, plus a community-driven, self-hosted, extensible codebase.

**Strengths:** One OpenAI-compatible endpoint for many models reduces integration work; Automatic load balancing helps keep high-concurrency workloads responsive; Transparent pay-as-you-go billing with real-time usage and cost tracking; Multi-user management with flexible permissions suits teams sharing infrastructure

**Limitations:** Requires technical setup and self-hosting knowledge to deploy your own gateway; Pricing details are not published openly on the public site, so you must sign up or contact the team for costs; Its value depends on the upstream providers you connect; it does not supply models itself; Advanced multi-user and permission configuration may feel complex for solo developers
