Plan feed, API and AI assistants

For comparison sites, aggregators, travel apps and AI assistants. Public catalogue data only — no customer data anywhere on this page.

Plan feed

Every plan we sell, public, no key, kept current with the catalogue — exactly the plans the website sells, at the price the checkout charges. Gzip and ETag are supported.

https://lempart.app/partners/plans.json

Destination, days, full-speed data per day, the speed after it, hotspot, networks, exit IP, the final price in USD and the page that sells the plan. Add ?ref=YOURCODE and every link carries your code.

Need the catalogue in another format, another field, or a webhook when prices move? Ask us — we make it for you.

Catalogue API

Read-only JSON over HTTPS at https://lempart.app/v1/, no key. Every call takes ?lang= (18 languages) and ?currency= (prices are always rechecked at checkout). Answers are wrapped as { "data": … }; errors as { "error": { "code", "message" } }.
