The carrier marketbehind one API

Send SMS and place calls on wholesale routes bought straight from carriers. One API key, billing per message and per call from your balance, no contract and no monthly fee.

Why build on PacketExchange

Carrier rates, fewer hops, no contract.

Carrier-direct pricing

Buy termination on the same wholesale market the aggregators buy from, without their retail markup. You pay the route rate plus a 2% platform fee, capped at $0.001 per call or message.

Quality you choose per destination

Every route shows its tier, its CLI type, the published ASR, ACD and PDD, and our Exchange Score. Ask for the cheapest, the best quality or a balance of both on each request.

Self-serve from the first call

API key on signup, scoped keys, idempotent requests and a history of every message and call. No sales call, no minimum commit, no monthly fee.

Use cases

Built for the traffic you actually send

OTP & 2FA

Send one-time codes over SMS on best-quality routes. A prepaid balance and spend alerts keep a pumping attack from running up a bill.

AI voice agents

Carrier termination for voicebots and outbound agents, with the CLI type of every route stated before you buy.

A2P notifications

Order updates, reminders and promotions to up to 1,000 numbers per request, from a numeric or alphanumeric sender.

Numbers and IVR

Local, national, mobile and toll-free numbers with IVR menus, forwarding, voicemail and business hours.

Programmatic provisioning

Buy routes, order numbers and create trunks from your code, with no sales call in the way.

MCP for AI agents

Point an AI agent at the MCP server and it can find, test and buy routes on its own.
