esimker sells prepaid travel data eSIMs: data only, no phone numbers, no SMS, no voice. Prices are USD strings, from $1.00. No accounts: an order is addressed by a secret token, a wallet by a secret code.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

search_destinations open 5h ago
Destinations on sale. `query` matches the name in any of 18 languages, the slug or the ISO code; empty lists everything. Each item: dest_code, slug, name, min_retail (USD, the cheapest fixed plan), unlimited_from (USD per day of a Daily Unlimited pass, or null), plan_count. Continue with get_plans(slug).

arguments 11 lines
get_wallet auth-required 5h ago
The wallet behind the code: ref (a public handle for support), balance_usd, cashback_percent, the deposit rules that apply to it now (min_usd, max_usd, first, bonus tiers), the last 50 transactions, orders (with their tokens — the wallet is where a buyer's order links are kept) and deposits. Needs the wallet code.

get_usage unknown never probed

Remaining data and status of an eSIM we issued.

arguments 13 lines

get_plans unknown never probed
The plans of one destination (slug from search_destinations). Each plan: id (the plan_id for an order), name, gb, days, retail (USD; per day when daily_unlimited is true), daily_unlimited, location_codes (the countries it covers), networks, speed, supports_topup. Also the published rating.

arguments 13 lines
get_payment_methods unknown never probed
Checkout methods open right now: "crypto" (a hosted invoice: BTC, ETH, TRX, USDT), "card", and "wallet" (a prepaid balance, see create_wallet). `gateways` names the providers behind each method; a checkout that does not ask for one by name goes to the first, which is what these tools do.

mcp-tool
{ "type": "object", "title": "get_payment_methodsArguments", "properties": {} }
arguments 5 lines

create_checkout unknown never probed

Create an order for a person to pay. Returns token, checkout_url (the gateway's page: hand it to the person) and order_url (the order page in `lang`, with the QR code once paid: show it to the buyer only, the token is a secret). Confirm the plan and the price first: every call creates a new unpaid order, so do not retry while a checkout is open. `email` (optional) also gets the eSIM by mail. `period_num` (1–365) only for daily_unlimited plans. `topup_iccid` with a plan_id from list_topups tops up an existing eSIM. A 403 means the caller's jurisdiction is embargoed. To pay from a wallet use purchase_esim.

get_order unknown never probed
An order by its token. status goes pending (unpaid) → paid → provisioning → ready; also expired, underpaid, failed_provisioning, gift_waiting. When ready, esim.activation_code is the LPA string (render it as a QR code), with iccid, smdp and matching_id. After payment poll every ~10 s; delivery usually takes under a minute.

{ "type": "object", "title": "get_orderArguments", "required": [ "token" ], "properties": { "token": { "type": "string", "title": "Token" } } }
arguments 13 lines
list_topups unknown never probed
Top-up plans that fit an eSIM we issued: plan_id, name, gb, days, retail. Order one with create_checkout(plan_id, topup_iccid=iccid) or, from a wallet, purchase_esim(plan_id, client_ref, topup_iccid=iccid).

arguments 13 lines
create_wallet unknown never probed
Mint a prepaid wallet with no account behind it and get its secret ONCE: `code` (32 hex characters) and the same secret as a 12-word `phrase`. Save the code before doing anything else and send it as `Authorization: Bearer <code>` on every wallet call; there is no recovery and no identity to prove. The balance is spent on eSIMs (retail price, cashback on every purchase) and never paid back out. accept_terms must be true (https://esimker.com/terms). Then create_deposit to fund it. Rate-limited and geo-blocked like checkout.

mcp-tool
{ "type": "object", "title": "create_walletArguments", "required": [ "accept_terms" ], "properties": { "accept_terms": { "type": "boolean", "title": "Accept Terms" } } }
arguments 13 lines
create_deposit unknown never probed
Open a top-up of the wallet and get what is needed to pay it. Floors: $10 for a wallet's first deposit, $1 after that; cap $1000 per deposit. Crypto deposits earn a bonus (+2% from $25, +3% from $50, +5% from $100, capped at $25); every purchase returns 3% cashback. With payment_method "crypto" pass a currency from: BTC, ETH, TRX, USDTTRC, USDTETH, USDTBSC — the answer then carries `pay`: the address, the exact amount in the coin (network fee included) and expires_at (about 15 minutes; after that open a new deposit). Send exactly `pay.amount` to `pay.address` on `pay.network`, then poll get_deposit(token) until status is paid. checkout_url is the hosted pay page for a person; card deposits have only that. Needs the wallet code.

mcp-tool

arguments 46 lines
get_deposit unknown never probed
One deposit of the wallet by its token: status pending → paid (credited, bonus included) | underpaid (nothing credited yet, the rest can still arrive) | expired. Poll every ~30 s after sending; crypto needs the network's confirmations. Needs the wallet code.

purchase_esim unknown never probed

Charge the wallet and issue an eSIM, no checkout. `client_ref` (1–64 chars) is your own reference for this purchase and makes the call idempotent: a retry with the same value returns the existing order without a second charge, so reuse it after a timeout and never invent a new one for the same purchase. `period_num` (1–365, default 7) only for daily_unlimited plans; the charge is price × days. `topup_iccid` with a plan_id from list_topups tops up an eSIM. Returns the order (status paid) with order_url; poll get_order(token) for ready and the activation code. A 402 is a short balance: create_deposit first. A wallet pays for at most 50 orders in 24 hours (429 beyond that; a retry answered from client_ref does not count). Needs the wallet code.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/5d78d4f4954893a0/badge.svg)](https://brick.blue/agent/5d78d4f4954893a0)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
