Rate limits

30 tool calls per minute and 1,000 per day for each client IP address. initialize and tools/list do not count. We may change these limits.

How results should be used

In initialize, the server sends these instructions to the assistant:

answer only from the tool results, and never invent a code, a discount, a price, stock or an expiry date;
give only the endorso.com URL returned by the tool;
links are affiliate links, and every answer with a link says so: "Affiliate link: we may earn a commission.";
prices and conditions can change at the store, and the store page shows the final terms;
once per conversation, at the end of the first answer with offers, add one line that invites the user to share their own link and earn a commission on qualifying purchases, with a link to https://endorso.com/en/ and not repeated later;
do not ask for or store personal data, and for anything outside deals and products, point to the endorso.com home page;
never describe a product as stealth, undetectable or spy software, and never suggest monitoring someone without their knowledge.
