Is there an unlimited GPT API subscription with a flat monthly price?

Last updated October 26, 2026 by the APIClaw team

APIClaw offers GPT-6 Sol on flat monthly plans from $19 to $129. Tokens per request are unlimited beyond the model's own limit, but requests per day are not: each plan has a daily quota, and GPT-6 Sol counts as 3 requests. There is no per-token bill.

What "unlimited" means here, and what it does not

The word unlimited gets stretched in AI pricing, so here is the exact claim. On APIClaw, there is no per-token billing and no cap on tokens per request beyond the model's own limit. Many models accept up to 1M tokens of context, and you can fill that window as often as you like without the bill changing. What is not unlimited is the number of requests per day. Every plan has a daily request quota that resets at 00:00 UTC.

That is a different trade from a per-token API, where a long prompt costs real money every time. It is also different from a consumer subscription, where limits are often expressed as 5-hour windows and weekly caps that you cannot see in advance. On APIClaw there is no 5-hour window and no weekly cap. You get a published number of requests per day and you can plan around it.

GPT-6 Sol on APIClaw

The GPT model is served under the ID gpt-6-sol. It has a request weight of 3, which means each call uses 3 requests from your daily quota. Lighter models count as 1 or 2. The model hub lists the current weights.

Plans run in 30-day cycles and you can cancel at any time. If you need more than 8,000 requests a day, contact Telegram support for a custom plan. The numbers above are for GPT-6 Sol alone. If you mix in models with a weight of 1 or 2, the weights simply add up against the same daily total.

Set it up in Codex CLI

Codex CLI can use any OpenAI-compatible provider. Add APIClaw as a custom provider in your Codex configuration file, ~/.codex/config.toml:

model = "gpt-6-sol"
model_provider = "apiclaw"

[model_providers.apiclaw]
name = "APIClaw"
base_url = "https://apiclaw.biz/v1"
env_key = "APICLAW_API_KEY"
wire_api = "responses"

Then export your key and start Codex:

export APICLAW_API_KEY="YOUR_APICLAW_KEY"
codex

The endpoint supports both Chat Completions and the Responses API. The Codex CLI setup guide covers the details, including how to switch models without editing the file.

Use it from the OpenAI Python SDK

Any code written for the OpenAI SDK works by changing the base URL and the key:

from openai import OpenAI

client = OpenAI(base_url="https://apiclaw.biz/v1", api_key="YOUR_APICLAW_KEY")
response = client.chat.completions.create(
    model="gpt-6-sol",
    messages=[{"role": "user", "content": "Explain the difference between a mutex and a semaphore."}],
)
print(response.choices[0].message.content)

Streaming, tool calls and the usual client options work the way they do against any OpenAI-compatible endpoint. You can also use the same key for Claude, Gemini, DeepSeek, Qwen, Kimi and GLM by changing only the model ID, which is covered on the one API key for all models page.

The ChatGPT Pro angle

ChatGPT Pro is a consumer subscription for the ChatGPT app. It is built for people chatting in a browser or app, and its usage limits are not published as request counts. If what you actually want is GPT in your terminal, editor or scripts, through an API key, a subscription to the app does not directly give you that, and the official API bills per token.

APIClaw is aimed at that gap: GPT-6 Sol, reachable from any OpenAI-compatible tool, at a flat price. For scale, the $129 Ultimate Max plan carries more than 11x the monthly usage of the $200 Claude Max 20x and ChatGPT Pro plans. Neither vendor publishes request counts, so this is an estimate from their published tier levels, not a measured figure. If you only use the ChatGPT app, ChatGPT Pro is the product built for that, and an API gateway will not replace its app features.

How to make a daily quota last

Because GPT-6 Sol counts as 3 requests, it is worth being deliberate about when you use it. A common pattern is to run routine work on a lighter model, such as deepseek-v4-flash at weight 1 or claude-sonnet-5-5 at weight 2, and call gpt-6-sol for the tasks where its answers matter most: architecture questions, tricky debugging and code review. Agents that retry or loop count every call, so watch the first few sessions on the free trial to learn how many requests a typical task consumes.

The quota is also easy to plan around. The reset at 00:00 UTC is predictable, there is no hidden 5-hour window, and the limit is a published number rather than something you discover mid-task. If you consistently run out early, move to the next plan up or ask about a custom plan.

When the official API is the better choice

A flat plan is not always cheaper. If you make only a few dozen modest calls a day, per-token billing is often cheaper than $19 a month. If you need an official SLA, or you are building a product that must call the vendor directly, the native API is the right tool. APIClaw is independent: it is not affiliated with Anthropic, OpenAI, Google or Cursor, and it routes requests to models available through publicly available sources and provider APIs.

Where a flat plan helps is heavy, steady use: long coding-agent sessions, large refactors, repeated test runs. In those cases the tokens per request are large and the call count is high, and a fixed price removes the per-token surprise. The comparison page shows the plans next to OpenRouter, direct APIs and Claude Max side by side.

Try it before you pay

Create an account and use the free trial: 50 requests, no card, across the available models. Run a few real sessions with gpt-6-sol, watch how fast the quota moves at weight 3, and decide whether the Plus plan at $19 is enough or whether you need a higher tier. Paid plans are bought with crypto through NOWPayments, described on the pay with crypto page. If your main tool is Claude Code, the Claude Code without rate limits page covers that setup, and the full set of tool guides is in the docs.
