    Median latency 514 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 514 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

Tools 10

check_esim_status

For a traveller who already bought a Slashtel eSIM: returns data used, data left, plan size, expiry, status (not yet installed, active, used up or expired) and whether automatic top-up (Keep me connected) is on. Needs the email used at checkout AND the eSIM's ICCID (the long number starting 89, shown in the order email and in phone settings under the eSIM). Both must match the same order. Use it when someone asks how much data they have left or why their eSIM stopped working.

Discovered
check_phone_compatibility

Explains how the traveller can confirm their own phone supports eSIM and is unlocked before buying, with steps for iPhone and Android. Optionally pass the phone brand to get brand-specific steps. Use it before create_checkout_link when the user is unsure their phone will work; an incompatible or locked phone is the most common reason an eSIM cannot be installed.

Discovered
create_checkout_link

Returns a slashtel.com link with the chosen eSIM plan or top-up already selected. Share it with the user: they enter their email and pay on the site. For type 'esim' pass plan_id. For type 'topup' pass phone, operator_code and send_value from get_topup_plans.

Discovered
create_price_alert_link

Returns a slashtel.com link that opens the free flight price alert form with the route filled in. The traveller enters and confirms their own email on the site, then gets an email when the fare drops. Nothing is created until they confirm.

Discovered
get_esim_plans

Live travel eSIM plans for one destination: data (GB), validity (days), price (USD) and price per GB. Use an ISO-2 country code (e.g. TR, JP, US, GB) or a destination code from list_esim_destinations. Optional filters narrow the list.

Discovered
get_flight_fares

Cheapest one-way fares by month for a route from Slashtel's flight fare tracker: price, airline and stops for each of the next 12 months on tracked routes (or the next 3 months on any other route), with the cheapest month. Pass IATA airport or city codes (LON, DEL, DXB, NYC, YTO, MNL...). Slashtel does not sell flights; fares are found in GBP from cached fare data and the airline charges in its own currency. Includes a source page to cite.

Discovered
get_flight_status

Live status of a flight by its number for yesterday, today or tomorrow: departure and arrival airports, scheduled and expected times, terminal, gate and baggage belt, whether it is in the air, its last reported position, and a slashtel.com link to see it live on the map and get a free email when it is delayed and when it lands. Use it when someone asks where a flight is, whether it is delayed, or when it lands.

Discovered
get_layover_esim

For a trip with a connection: finds Slashtel travel eSIM plans that cover the transit hub's country AND the destination country (and an optional second stop) on one QR code, cheapest first, with live prices in USD. Use it when someone flies via Dubai, Doha, Istanbul, Abu Dhabi, Singapore, Hong Kong, Frankfurt, Amsterdam, Paris, London or another hub and wants data during the layover and on arrival without relying on airport wifi. If no single plan covers every country it returns one eSIM per country. Follow up with get_esim_plans using the returned code to get plan_ids, then create_checkout_link.

Discovered
get_topup_plans

Mobile recharge: detects the operator of a mobile number and returns the live recharge and top-up options for it (airtime, data packs and plans): what the recipient receives, validity where it applies, and the price in USD. The number must include the country code, e.g. +911234567890.

Discovered
list_esim_destinations

Lists every country and region Slashtel sells travel data eSIMs for (about 200 destinations), returning each destination's code, name, lowest live price in USD and number of plans. Use it to find the destination code when the user names a place, a region such as Europe or Asia, or is unsure what is covered. Optional search text filters by name. Skip this tool and call get_esim_plans directly when you already know the ISO-2 country code.
