Your AI agent can now earn affiliate commission on travel eSIMs (MCP)

Disclosure: I run MonoEsim, the service described here.

Most affiliate programmes assume a human with a blog. But a growing share of "where should I buy X?" answers now come from AI agents — Telegram bots, custom GPTs, Claude and Gemini agents. So we asked: what if the agent could join the affiliate programme by itself?

MonoEsim sells prepaid travel data eSIMs for 197 countries and 11 regional packs. Our public MCP server already let agents search and compare plans with live EUR prices. Version 1.5.0 adds five tools that turn an agent into an affiliate.

The affiliate flow

1. register_affiliate — called without an API key:

{
  "owner_email": "[email protected]",
  "agent_name": "TripBot on Telegram",
  "promotion_plan": "Answers travel questions in my Telegram channel about Turkey; posts are marked as ads",
  "accept_program_rules": true,
  "lang": "en"
}

It returns a one-time API key straight away.

1. The human owner confirms by email. The link opens a page with the rules and a confirm button (link scanners that prefetch URLs confirm nothing). Then we review and approve the partner account.

2. With the key (Authorization: Bearer mak_…):

   • get_affiliate — status, referral link, clicks, sales, balance (available / on hold / paid)
   • get_referral_link — a tracked link for any destination or a specific plan: …/destinations/japan?plan=<id>&ref=<code>
   • list_affiliate_sales — sales and commission, no customer data
   • request_payout — asks for a payout once the balance is payable

Money stays with the human

• 10% commission on every delivered eSIM bought through the link.
• Payouts go only to the bank/PayPal details the owner saves in the partner portal. No tool can set or change them, so a leaked key can't redirect money.
• Commission becomes payable after the refund window; minimum payout €25; no commission on own purchases.

Rules (the agent receives them too)

Promote only where ads are allowed and mark them as ads; no spam, no unsolicited DMs, no fake reviews; never pretend to be MonoEsim; quote only prices returned by the API. Breaking them blocks the key.

Feedback on the design is very welcome — especially from people building agents that recommend products.
