    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Cancel an unused eSIM and receive a refund to your wallet balance. Only works if the eSIM has not been installed or activated. Requires an agent-wallet API key (ak_live_).

    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Cancel a long-term SMS rental and refund the full amount to the wallet. Only works within 2 hours of purchase AND only if the number has NOT received any message — this mirrors the provider refund window, so if the window has passed or a code already arrived it returns a clear reason and refunds nothing (the number worked). Use for a genuine change of mind or a wrong purchase shortly after renting. The receiptId comes from rent_sms_number or list_sms_orders. Requires a connected agent wallet.

    Description, as the server wrote it
    Extend a long-term SMS rental so the user keeps the same number — days are ADDED on top of the current expiry. This SPENDS the wallet balance at the live tier price (the tool checks the price first and reports what was charged). Valid day options are the same duration tiers the rental was offered at.

    Description, as the server wrote it
    Buy a QUICK SMS verification number: returns a temporary phone number the user enters on the target service, then the incoming code is read with check_sms_verification. This SPENDS the wallet balance (typically $0.50-$5). Single-use, valid 20 minutes, auto-refunds if no SMS arrives.

    Description, as the server wrote it
    Purchase a DATA eSIM. Deducts from your prepaid agent wallet and returns order details with activation info (ICCID, QR code, SM-DP+). Use the packageCode from search_esim_packages. For a daily-reset "Unlimited" plan, also pass days (the number of days to buy). For phone-number eSIMs use purchase_phone_plan instead. Requires an agent-wallet API key (ak_live_).

    Purchase a PHONE-NUMBER eSIM — a plan with a real carrier phone number (voice + SMS + data). Deducts from your prepaid agent wallet and returns order details with activation info (ICCID, QR code, SM-DP+). The real phone number is assigned by the carrier when the eSIM registers on the network and appears in the device settings after activation. Use the packageCode from search_phone_plans. Plans whose search result says "designated-date activation" REQUIRE activationDate. Requires an agent-wallet API key (ak_live_).

Use list_sms_rentals first for rentalId, valid day tiers, prices, and live stock (do not order an OUT OF STOCK tier). Extendable before expiry with extend_sms_rental, and cancellable for a full refund with cancel_sms_rental within 2 hours if no messages arrived.

    Description, as the server wrote it
    Adds more data (and on some plans voice/SMS) to an existing eSIM the user already owns, without issuing a new eSIM. This SPENDS the wallet balance and cannot be undone. First call get_topup_options with the same ICCID to get valid top-up package codes and prices, then pass one here.

    Why it is in this group

    • The name "create_deposit" says "create": a word for a change.
    Description, as the server wrote it
    Creates a payment invoice to add funds to the connected prepaid PikaSim Wallet, and returns a payment page link (the human can pay by card with 3D Secure, or crypto) plus per-coin crypto payment details. Accepts Bitcoin, Lightning, Monero, Zcash, USDT, and 50+ altcoins, or card on the payment page. Does not move funds itself; it returns an invoice the user pays externally, and the balance updates once the payment confirms. Use when check_balance is too low to purchase. Minimum deposit is $1 (no prepaid float required). A fully-autonomous agent holding crypto can pay WITHOUT a human: the tool returns native destinations for Lightning, Bitcoin on-chain, USDT (TRC-20/Tron), and Monero — pay the amount to any one of them. Crypto has no fee; card payments add a 2.9% processing fee on top of the credited amount. Balance is prepaid credit for purchases on PikaSim, never expires, and is not redeemable for cash. Requires a connected agent wallet (OAuth or ak_live_ key).

    Description, as the server wrote it
    Create a NEW PikaSim agent wallet for autonomous purchasing — no human, no browser, no account, no email, no KYC. Returns a wallet code + an ak_live_ API key + a small spend-only welcome credit (spendable on eSIM data only; SMS verification numbers need a deposit from $1), so you can immediately reconnect with the key (Authorization: Bearer ak_live_…) and buy an eSIM, phone number, or SMS verification number. Use this when the user has NO wallet yet and wants their agent to buy. If the user ALREADY has a wallet, do NOT create a new one — reconnect the existing wallet instead (ask them for it). You accept the Terms of Service (https://pikasim.com/tos) on the user's behalf by passing acceptTos=true.
