## 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

## LLMFly AI

LLMFly AI positions itself as a single API layer in front of several frontier model families. Instead of maintaining a separate integration, billing relationship and SDK for every provider, developers point their server-side OpenAI client at the LLMFly AI base URL, swap in an API key and a model ID, and keep using the tooling they already have. The site emphasises drop-in compatibility with the OpenAI SDK as well as Anthropic SDK and common coding agents such as Claude Code, Codex and Cursor.

The platform is oriented around cost visibility and day-to-day operational support. Each model in the catalog lists its own input, output and, where available, cached-token rates, and pages let you compare official reference prices against current LLMFly AI rates. Per-application keys, usage records and rate inspection are meant to support development workflows, cost reviews and troubleshooting. The company also advertises one-to-one technical assistance covering setup, failures, rate limits and client errors.

The catalog is described as changeable — availability shifts over time — so the recommended workflow is to check the model list for current model IDs before sending a request, starting with a short non-streaming call. New accounts are offered free credits and a referral reward. Note that LLMFly AI is an independent third-party gateway and is not affiliated with the model vendors whose names appear in its catalog.

**Pricing & Plans:** Paid, usage-based. Access is billed per model with separate input, output and (where available) cached-token rates; usage history shows what each request consumed. New sign-ups get free starter credits plus a referral reward.

- **One OpenAI-compatible endpoint:** Call GPT, Claude, Gemini and Grok models by changing only your base URL, API key and model ID, keeping your existing OpenAI or Anthropic SDK code largely intact.
- **Per-model rate transparency:** Each catalog entry publishes its own input, output and cache pricing, with side-by-side comparisons against official reference rates.
- **Key management and usage records:** Issue separate keys per application and environment, then inspect usage records to support cost reviews, debugging and rate-limit investigations.
- **Works with coding agents:** Copy the provided integration guide straight into Claude Code, Codex or Cursor, or call the endpoint from backend services and automation scripts.
- **One-to-one technical support:** Direct assistance covering initial setup, everyday requests, failures, rate limits and client errors.

**Strengths:** Single endpoint and credential set replaces multiple provider integrations; Per-model pricing is published alongside official reference rates; Separate keys per app and environment simplify cost attribution; Explicit support for popular coding agents and both OpenAI and Anthropic SDKs

**Limitations:** As a third-party gateway it adds a dependency between your app and model vendors; Model availability can change, so model IDs need periodic verification; Pricing is usage-based per model, which makes costs harder to predict than a flat plan
