Phone Infrastructure For AI
The first phone carrierbuilt for AI agents.

It's not an AI voice platform.It's the carrier underneath it.
Saperly owns the number, the routing, the compliance, and the record. The conversation runs on hosted handling or your own runtime.
Numbers With Agent Routing
A Saperly number is the phone identity. A connection tells it where the conversation should run: hosted voice agent or your own runtime. Update routing without rebuilding telecom.

Real Numbers, On Demand
Provision and release live phone numbers in one call, then route voice and SMS however your operation needs. Each number carries its own spend cap and audit trail.

Hosted Or Manual Runtime
Hosted runs the voice agent in-network. Manual points the call at your own runtime and relays turns as text plus tool calls. Either way, audio stays in the carrier.

[ Integrations ]
Make any agent phone-reachable.
Agents you already run — on Cofounder, Polsia, OpenClaw, or Claude — can pick up the phone, with their tools, memory, and context intact. Connect over a standard API or MCP.
[ By The Numbers ]
Built For Scale.
Attach multiple numbers to the same connection when they should use the same hosted or manual handling.
Disclosure, consent, guardrails, and 10DLC are enforced independent of the model — every call, every market.
Spend caps and number allow-lists keep each agent inside its limits, with every action on the record.
Real numbers and compliant routing across markets, so your agents transact wherever your business runs.

[ FAQ ]
Frequently Asked Questions.
Saperly is the phone carrier for AI agents. One API call gives any AI agent a real phone number with voice, SMS, identity, and compliance built in — no carrier account or telephony paperwork required.
A connection is a reusable handler — instructions and a voice — that you define once and attach to any number of phone numbers. One connection can power a fleet of ten thousand numbers, so configuration is shared rather than duplicated per line. Any opening line goes in the instructions; the only forced opener is the TCPA compliance disclosure.
Compliance is enforced before a call connects, not bolted on afterward. Every Saperly number carries automatic AI disclosure, first-class consent records that are checked at call time and revocable, and an append-only audit trail of every call and compliance event.
Yes. The same number does inbound and outbound voice and SMS. SMS includes STOP/HELP keyword handling and the same consent and audit guarantees as voice.
Yes. Saperly registers your brand and campaign for 10DLC (the carrier registration US application-to-person SMS requires) as part of provisioning, so messages are sent over compliant, registered routes rather than being filtered or blocked.
Saperly is prepaid and pay-as-you-go. Every new account starts with $5 of free usage that never expires — enough to cover your first phone number and early calls and messages. You top up a balance and usage is metered per call and per message.
No. Saperly owns signaling, identity, compliance, the record, and billing, but conversation media stays in-network on the underlying carrier — call audio never passes through Saperly compute.

Provision a line, attach a connection, and go live. New organizations start with a $5 credit.
