Every endpoint on this page is public, unauthenticated and free to use. If you are an AI agent helping someone pick a travel eSIM, start here.
Public endpoints
Read-only JSON. No API key, no registration, no token to mint.
/data/esim-prices.json- Every sellable destination in one document: 452 rows, ~10 KB gzipped. Each row carries slug, name, type, region, url, from_price and durations_days. from_price is a decimal in the response currency, not minor units. Send Cookie: currency=EUR to pin the currency.
/feed.json- Array of Product JSON-LD nodes for the featured destinations.
/llms.txt- Compact index of the site for answer engines. /llms-full.txt inlines the complete text of every article and glossary term.
Any page as markdown
Request any URL on this site with Accept: text/markdown and
you get the page as clean markdown instead of HTML: headings, prose, price tables and links,
with the navigation, scripts and styling stripped. A destination page drops from roughly
123,000 tokens of HTML to under 4,000. The response carries
x-markdown-tokens so you can see the saving.
Discovery documents
/.well-known/api-catalog- RFC 9727 linkset. The machine-readable entry point.
/.well-known/openapi.json- OpenAPI 3.1 description of the endpoints above.
/.well-known/agent-skills/index.json- Agent Skills Discovery v0.2.0 index, with a SHA-256 digest per skill.
/auth.md- How authentication works here. Short version: it does not, because nothing public needs it.
/robots.txt- Crawl rules plus Content-Signal, declaring search, ai-input and ai-train preferences.
In-browser tools
Every page registers read-only WebMCP tools when the browser supports
navigator.modelContext: search destinations, look up
prices, open a destination page. They read the same price index documented above, so a
slug from search works directly in the other two. Nothing that spends money is exposed,
deliberately.
What is not open
Order, payment and account endpoints are first-party only, so an agent cannot buy on a customer's behalf. Send the traveller to the destination page to complete the purchase. For a commercial integration, the affiliate programme is the route.
