## 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

## GPTProto

GPTProto is an API aggregator that puts a large catalogue of third-party AI models behind a single, OpenAI-compatible endpoint. Instead of opening accounts with each provider and juggling separate keys, quotas and invoices, you fund one balance and call models by name. The advertised catalogue covers 200+ models spanning language models for chat and coding, image generation, video generation and audio, drawn from well-known vendors such as OpenAI, Anthropic, Google, DeepSeek and Moonshot, plus image and video specialists.

The integration story is deliberately conventional. You generate an API key, point your client at the GPTProto base URL, and keep the same request and response shapes you already use — the site claims your code runs unchanged apart from the base URL and key. Because the platform sits between you and the providers, it can also handle routing, so a model that is rate-limited, retired or removed can be swapped for another through configuration rather than a rebuild, and prompt caching still applies to long system prompts. Per-model rates are published in the catalogue, covering per-token, per-image and per-video pricing, and the platform advertises those rates as below buying direct, with larger credit purchases earning a percentage bonus.

The commercial model is purely usage-based. There is no monthly subscription: you top up in increments from roughly fifteen dollars up to several thousand, receive a small bonus percentage at higher amounts, and the balance is consumed as you make calls. The company also offers an in-browser generator and prompt libraries for people who want to experiment before writing code, and an OpenAI-compatible API for agent frameworks, CLI coding tools and roleplay front-ends. It is a practical choice for teams that already work across several providers and want the model choice to be a configuration detail rather than an integration project.

**Pricing & Plans:** Pay-as-you-go with no subscription. You top up credits in one-time payments from around $15 up to $5,000 and beyond, with a bonus of roughly 3-7% added at higher tiers; the credited balance is then drawn down at each model's published per-token, per-image or per-video rate.

- **One OpenAI-compatible key:** Connect with the base URL https://gptproto.com/v1 and reuse your existing OpenAI-style request and response shapes across every model in the catalogue.
- **200+ models, one balance:** Text, image, video and audio generation are all served through the same balance and account, so you replace several vendor subscriptions with one.
- **Routing and failover:** Route requests across providers so a dead or retired route can be moved with a configuration change instead of a code rewrite.
- **Pay-as-you-go credit top-ups:** Top up in increasing increments from around $15 to $5,000 and above, with a bonus percentage added at higher tiers and no recurring commitment.
- **Developer dashboard and playground:** Inspect models, issue and rotate API keys, check balances and try prompts from the dashboard or an in-browser generator before wiring anything up.

**Strengths:** One OpenAI-compatible key and one balance replace multiple provider accounts and subscriptions.; Pay-as-you-go pricing means no recurring commitment and no unused monthly quota.; Model choice becomes a configuration change, which simplifies switching and fallback when a route dies.; The catalogue spans text, image, video and audio, so a single account covers very different workloads.

**Limitations:** You are dependent on an intermediary: provider-side changes, rate limits or outages can reach you through the aggregator.; Bonus tiers encourage larger upfront top-ups, so money sits in the account before it is spent.; Model names in the catalogue go well beyond mainstream lineups, so you need to check exactly what each route serves before committing.
