eSIM Access API Skill

Interact with the eSIM Access API for complete eSIM lifecycle management.

When to Use This Skill

Use this skill when the user:

• Asks about eSIM operations: ordering, top-ups, cancellations, status checks
• Mentions ICCID, order number, QR code, or data usage
• Wants to check account balance or list available data packages
• Asks about roaming, travel data plans, or mobile connectivity
• Needs to manage eSIM profiles (suspend, unsuspend, revoke)
• Wants to configure webhooks for eSIM status notifications
• Asks to cancel and reissue an eSIM (refund/replace workflow)
• References the eSIM Access API or api.esimaccess.com

Example prompts

• "Check my eSIM Access balance"
• "What packages are available for Japan?"
• "Order a 5GB plan for the US"
• "Check the status of order B26041021130002"
• "How much data has ICCID 89852240810733629810 used?"
• "Top up my eSIM with another 5GB"
• "Cancel this unused eSIM and get a refund"
• "Set up a webhook for order notifications"

Quick Reference

• Base URL: https://api.esimaccess.com/api/v1/open
• Auth: HMAC-SHA256 signed headers — the accessCode is used as both the API identifier and signing key (see references/api-reference.md)
• Prices: API values / 10,000 = USD (e.g., 18000 = $1.80)
• Volumes: Bytes (1073741824 = 1 GB)
• Credentials: Get your accessCode from https://console.esimaccess.com/developer/index

Operations

Read (safe)

Operation	Endpoint	Purpose
check_balance	/balance/query	Account balance in USD
list_regions	/package/list	All supported countries
list_packages	/package/list	Products by country/code
list_topup_packages	/package/list	Top-up options for ICCID
check_order_status	/esim/query	Order details + ICCID
check_esim_status	/esim/query	Full eSIM profile info
check_data_usage	/esim/usage/query	Data consumption stats
query_webhook	/webhook/query	Current webhook config

Write (costs money or modifies state)

Operation	Endpoint	Purpose
create_order	/esim/order	Purchase new eSIM
apply_topup	/esim/topup	Add data to existing eSIM
cancel_esim	/esim/cancel	Cancel unused eSIM (refund)
suspend_profile	/esim/suspend	Temporarily disable
unsuspend_profile	/esim/unsuspend	Re-enable suspended
revoke_profile	/esim/revoke	Permanently disable (no refund)
send_sms	/esim/sendSms	Send SMS to eSIM
setup_webhook	/webhook/save	Configure notification URL

Composite Workflows

Operation	Purpose
refund_and_reissue	Cancel unused eSIM, verify refund, order replacement with same package

Key Rules

1. Order flow: create_order returns orderNo. Poll check_order_status every 3s (4 retries) for ICCID. ORDER_STATUS webhook is fallback.
2. Top-ups: Use esimTranNo (not ICCID). supportTopUpType === 2 means eligible. Cannot top up after expiry.
3. Cancel vs Revoke: Cancel works on unused eSIMs (RELEASED/GOT_RESOURCE) and provides refund. Revoke works on activated eSIMs with no refund.
4. Usage query: Requires esimTranNo, not ICCID. Do an ICCID lookup via /esim/query first if needed.
5. SMS: Uses message field (not content). Only works on activated eSIMs.

Authentication in Any Language

The references/api-reference.md file contains HMAC-SHA256 auth examples in both Node.js and Python. Ask your AI to generate auth code in your preferred language using the signature algorithm documented there.
