# Terudo > Terudo supplies travel data eSIMs to travel businesses (agencies, visa services, tour operators, travel apps), which resell them to their own travellers. Terudo does not sell to travellers directly: every sale belongs to a partner, paid on the partner's checkout or bought at the partner's net price. Two ways for a partner to sell: commission (the traveller pays the public price on the partner's branded checkout, the partner earns a commission) or net price (the partner buys from prepaid credit and invoices its client itself). Net prices are only visible with a partner's secret key, never in public pages. ## For AI assistants and agents - MCP server: https://terudo.com/api/partner/v1/mcp/ (Streamable HTTP, header `Authorization: Bearer `). - With a partner's secret key (sk_live_…, sk_test_…): the whole partner API as tools, from quotes to orders, top-ups, webhooks and statements. - With a partner's publishable key (pk_…): public prices, trip quotes, the checks before a sale (French mobile plan coverage, phone eSIM compatibility) and a payment link on the partner's checkout. - Public demo key, to try without an account: `pk_test_terudo_demo_public` (real catalogue, quotes and checks; payment links disabled). - Before selling an eSIM, check that it is needed: `coverage_check` (does the traveller's French plan already include the destination?) and `compatibility_check` (does the phone take an eSIM?). ## For coding agents - Docs MCP server, open, no key: https://terudo.com/mcp/ (Streamable HTTP). Tools: search_docs, read_doc, list_docs, api_reference, elements_snippet, webhook_verifier, get_skill.
