Saperly

Overview

Saperly sells phone numbers for AI agents, with voice and SMS on the same number. The model is connection-first: you define a connection (instructions and a voice) once and attach it to one or many numbers. A connection runs either a hosted voice agent or your own LLM in manual mode, and call audio stays in the carrier network. Its terms describe Saperly as a reseller of an underlying carrier. It has no iMessage, RCS, WhatsApp or email.

Key features

• Provision and release numbers by API, with caller ID name and international sender IDs
• Hosted voice agent, or manual mode that sends text turns to your own LLM
• Call transfer to a phone number, call recording, and MCP tools inside calls
• SMS with STOP and HELP handling and managed 10DLC registration
• Consent checks and AI disclosure enforced before a call or message goes out
• Scoped API keys with spend caps and number allow-lists
• Node and Python SDKs, a remote MCP server and HMAC-signed webhooks

Pricing

Prepaid and pay-as-you-go, starting with a $5 credit that never expires and no card. Voice costs $0.13 a minute with your own LLM or $0.26 hosted, at one rate to any country. SMS costs $0.02 a segment in the US and Canada, more elsewhere, with inbound included. Numbers start at $2 a month. Enterprise pricing is custom.

How it compares to Linq

Linq is built around iMessage, with RCS and SMS fallback; Saperly has no iMessage or RCS. Saperly's API places and answers AI voice calls, which Linq's API does not. Saperly charges per minute and per SMS segment, while Linq charges a flat monthly fee from $260 with no per-message fees. Saperly blocks outbound contact until consent is recorded. Linq states SOC 2 Type II; Saperly names no certification and its terms offer no uptime SLA yet.

Best for

Teams building voice or SMS agents that need numbers with consent and disclosure rules enforced by the provider.
