The SMS Provider Auction
Credibility concern recorded. The source reference remains available for verification and correction.
SMSRouter offers one API that compares multiple SMS-verification providers, buys an available number, and forwards the received code.
Field notes
The routing engine compares live availability and price across four named SMS providers, then purchases from the selected winner. Developers can use the dashboard or a common API response format, with inbound messages delivered through signed webhooks rather than polling. The integration boundary is unusually explicit: each provider implements six methods, including price lookup, number purchase, SMS retrieval, cancellation, and balance checks. Deposits are crypto-only and include a stated 1.5% top-up fee.
