ATXP routes the same 400+ frontier models OpenRouter does — at a 0.50% platform fee instead of 5.5%. Plus a chat UI, image, video, voice, search, and agent tools on the same balance.
OpenRouter charges a 5.5% platform fee on top of provider rates. ATXP charges 0.50%. Same model prices passed through. Same volume discounts. The difference compounds the more you spend.
| Annual token spend | OpenRouter (5.5%) | ATXP (0.50%) | Saved |
|---|---|---|---|
| $10,000 | $550 | $50 | $500 |
| $100,000 | $5,500 | $500 | $5,000 |
| $1,000,000 | $55,000 | $5,000 | $50,000 |
| $10,000,000 | $550,000 | $50,000 | $500,000 |
Math is the same model prices, with a different platform-fee multiplier. We make our real margin on the agent infrastructure layer above the tokens — tools, agents, MCP servers — not on the tokens themselves.
Routing infrastructure is solved — OpenRouter pioneered it. ATXP is the same routing layer at a tenth of the markup, with the surface layer on top: chat, tools, agents, all on one balance.
An honest line-by-line against the main AI gateways. The 0% markups look great until you read the parenthetical — bundled plans and per-log fees are where pricing actually lives.

We make our margin on the agent infrastructure layer above the tokens — tools (image, video, voice, search, SMS), MCP servers, and managed agent runtime. Routing tokens is plumbing; we don't need to charge platform-grade margins on it.
Yes. Anthropic, OpenAI, Google, xAI, Mistral, DeepSeek, and others all pass through at their published rates. Volume discounts we negotiate get passed through too. The only thing on top is the 0.50% platform fee.
We expose a model-call API similar in shape to OpenRouter's. You point at our endpoint with your API key and the same model identifiers work. Tools, agents, and MCP servers are additional endpoints on the same balance.
Included for free at chat.atxp.ai. Same provider list, same balance, same pricing as the API. Give it to your team and stop paying $20–30/seat for ChatGPT Business.
Yes. Route some workloads through your existing Anthropic / OpenAI / Google contracts, others through ours. Useful when you have pre-paid commitments to burn down.
None. Pay-as-you-go from $0. Free credits to try. No card required to start. Spin it up, run real traffic, and only fund the account when you're ready.
Drop-in compatible API, public docs, no sales call required. Your agent reads the docs, gets an API key, and routes real traffic in minutes.
