How this service works
Top up a phone number
Output
A confirmation that the phone number's expiry has been extended by 30 days from its current expiry date. Top-ups stack, so multiple renewals can be applied in advance. Anyone can top up a number, not just the original purchaser.
Example use cases
Example prompt
“Top up my StablePhone number +14155551234 to extend it by 30 more days — go ahead and pay the $15 to keep it active.”
Technical details
Endpoint
POSThttps://stablephone.dev/api/number/topupWhen to prefer
Use this endpoint when you have an existing StablePhone dedicated number that is approaching its expiry date and need to extend it for another 30 days. Unlike buying a new number, this preserves the same phone number and caller ID. Top-ups can be stacked proactively before expiry. Choose this over re-purchasing when number continuity matters.
Side effects
- Invalid or unrecognized phone number — number not found in StablePhone system
- Insufficient USDC balance or payment failure via x402 protocol
- Phone number already permanently cancelled and ineligible for renewal
- Network or API error returning 5xx status
