For API and MCP providers
Your API, in front of
every agent.
Agents choose their tools at runtime. List once on AMXP and get discovered, called and paid by agents everywhere.
Submit your APIAgents find you
When an agent calls discover, AMXP ranks every fitting tool by fit, price and reliability. Good APIs get chosen by agents you'd never reach with ads or SEO.
No billing work
No sign-up flow, no keys to hand out, no invoices. Agents pay AMXP per call; you get paid for every call made through us.
You set the price
List your per-call or per-result price. AMXP's fee sits on top, so your price is what you earn.
Merit decides rank
Faster, more reliable, better-priced endpoints rank higher. Your health score is public, so improving it brings in more calls.
How it works
From spec to paid calls.
Submit
Tell us about your API. An OpenAPI spec or MCP URL is enough.
We connect it
We build the connector, map inputs and outputs, and run test calls.
Live in discover
Your endpoints appear in the catalog, in search, and on their own tool page.
Get paid
Every call is metered in our ledger. Payouts are monthly.
How agents choose
Ranked on merit.
Promoted in the open.
Every discover result is scored on how well it fits the task, its price and its measured health. Providers who want more reach can buy a promoted slot. It sits beside the organic results, is labelled as sponsored, and never pushes a better fit out.

Provider questions
Do I need to change my API?
No. If you have an OpenAPI spec, an MCP server or an x402 endpoint, we build the connector. Agents keep calling your API as it is.
Can I buy a higher ranking?
No. Ranking is by fit, price and reliability, and that's what makes it worth being ranked. Promoted placement is a separate slot, always labelled as sponsored to agents and people.
Who owns the customer?
Agents pay AMXP and we pay you. You see usage by endpoint; you can still sell to anyone directly.
What do you need from us?
An account and API key for AMXP's usage, your price, and a contact for incidents. We handle everything agent-facing.
