## 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

## LLM Gateway

The core problem LLM Gateway solves is provider sprawl: separate API keys, separate dashboards, and code that breaks whenever you switch models. With the gateway in place, a single request can be routed to 250+ models across 40+ providers, and switching a model is often a one-string change. It ships with an AI SDK provider plus compatibility with any OpenAI SDK, cURL or language client, and supports chat completions, responses and image generation endpoints.

Beyond routing, the gateway is a control plane. Teams get unified key management, spend caps per API key or member, automatic failover that retries on another provider within the same request when a provider errors or rate-limits, and guardrails such as prompt-injection detection and PII redaction so sensitive data can be caught before a provider sees it. A dashboard covers requests, tokens, cost per 1K tokens, latency, error rates, cache hit rates and per-model/per-provider breakdowns, with audit logs and SSO on Enterprise.

Deployment is flexible: it can be run by the vendor as managed cloud with an SLA, or self-hosted via Docker or Kubernetes on your own infrastructure, which is what makes it attractive to privacy-sensitive teams. The core gateway is open source under AGPLv3, with source-available enterprise features. The company reports SOC 2 Type II compliance, and pricing starts with a bring-your-own-keys free tier, a small markup on credit top-ups for pay-as-you-go usage, and a custom Enterprise plan.

**Pricing & Plans:** LLM Gateway is freemium. Routing and analytics on your own provider keys are free forever with no credit card, pay-as-you-go credits are billed at provider list prices with a small top-up markup, the open-source core can be self-hosted at no cost, and Enterprise adds SSO, audit logs, guardrails, a 99.9% SLA and provider policy controls under a custom quote.

- **Unified OpenAI-compatible API:** Keep your existing OpenAI SDK code and change only the base URL to reach 250+ models from 40+ providers through one integration.
- **Automatic failover and routing:** If a provider errors, times out or rate-limits, the gateway can retry up to twice on another provider within the same request, so your app still gets a response.
- **Cost, latency and spend analytics:** Track requests, tokens, total spend and average cost per 1K tokens, plus per-model and per-provider breakdowns, cache hit rates and error monitoring.
- **Guardrails and key security:** Detect prompt injection, jailbreak attempts, PII, card numbers and secrets, then block, redact or warn; manage all provider keys in one scoped dashboard.
- **Self-hosted or managed deployment:** Run the AGPLv3 open-source gateway on your own Docker or Kubernetes infrastructure, or let the vendor host it as managed cloud with an SLA.

**Strengths:** One API key and one integration replace a pile of provider SDKs and dashboards; Open-source core under AGPLv3 with a genuine self-hosting path, not just a hosted SaaS; Depth of observability: cost, tokens, latency, errors, cache hits and per-project breakdowns; Built-in failover and spend caps live in the gateway rather than in application code

**Limitations:** The most valuable governance features — guardrails, SSO, audit logs and provider policy routing — are Enterprise-only; Pay-as-you-go credits carry a small markup over provider list prices, so high-volume users may prefer their own keys; A gateway adds an extra hop and a component to operate, which is overkill for teams using a single model
