How this service works
United States 500 MB: a prepaid travel eSIM with 500 MB of data for 1 day. Buy it when a traveller needs mobile data abroad without a local SIM card or roaming fees. Pay in USDC on Base with x402, no account or API key needed. The installable eSIM (QR code, LPA activation code, one-tap iPhone and Android links) is ready within seconds from order_status_url. Optional JSON body: quantity (1 to 20) and email.
Output
Returns an order_status_url where the eSIM installation materials (QR code, LPA activation code, one-tap iPhone and Android install links) are available within seconds. If an email was provided, the same activation details are also sent to that address. One eSIM per unit purchased, up to 20 per call.
Example use cases
Last-minute USA trip data plan
“I'm flying to the US tomorrow and need a quick data eSIM — can you buy me one 500 MB US eSIM and send the activation link to sarah@gmail.com?”
Bulk eSIMs for travel group
“My team of 5 is heading to the United States this week and everyone needs mobile data — grab 5 of those 500 MB US eSIMs and send the details to our coordinator at ops@company.com.”
Crypto-native travel connectivity
“I want to pay with USDC for a prepaid US eSIM right now — no account, just get me 1 eSIM for the United States with 500 MB so I can grab the QR code from the order link.”
Technical details
Endpoint
POSThttps://simfuse.app/x402/purchase/01kvmtdbybqar2qewyaf9wzf1kWhen to prefer
Use this endpoint when a traveller needs instant, no-account mobile data in the United States and wants to pay with USDC on Base via x402 with no API key or registration required. Ideal for AI agents automating travel logistics or for users who want crypto-native connectivity. Choose this over traditional eSIM stores when frictionless programmatic purchase is needed, and choose the US-specific plan (vs Europe or other regional siblings) when the destination is specifically the United States.
Side effects
- Insufficient USDC balance — payment via x402 fails if the wallet lacks enough USDC on Base
- Invalid quantity — values outside 1–20 are rejected
- Malformed email — poorly formatted email string may be rejected or silently ignored
- Network or provisioning delay — eSIM not immediately visible at order_status_url in rare cases
- Device incompatibility — eSIM activation may fail if the traveller's device does not support eSIM or is locked
