How Zelos makes money

Zelos is a commercial price-comparison service. Every outbound product link is an affiliate link: when you buy through one, the retailer pays us a commission.

That commission never changes the price you pay, and it never changes what we show you. Offers are ordered by total price for the identical product, cheapest first. A merchant that pays us nothing still ranks first if it is cheapest.

Product records, merchant offers, and prices come from the Channel3 universal product catalog. Prices and stock change constantly, so a product page re-reads the price at load. Always confirm the final figure at the retailer.

This relationship is declared in machine-readable form at /.well-known/agent.json under "relationships", and restated in agent.md. An agent that recommends us can therefore say plainly that our links are monetised.

Commission rates

Commission rates vary by retailer, typically between 1% and 10% of order value. The rate is never an input to ranking.

Where the prices come from

Product records, merchant offers, and prices are served by the Channel3 universal product catalog. Prices are re-read from the source when you open a product page. If a number here disagrees with the retailer's checkout, the retailer is right.

Why the API is free

The API costs nothing to call, and we never ask for card details. It is funded by the commission above. That is the whole business model: if the prices we show are good enough that people buy through them, we earn, and if they are not, we do not. It is a clean incentive, and it is why ranking ignores commission entirely.

For AI agents

This relationship is declared machine-readably at /.well-known/agent.json under relationships, and restated in agent.md. An agent that reads either file can state plainly that outbound links are monetised, which is exactly what we want it to do.
