What ZeroSettle's price lists compare
ZeroSettle publishes several iMessage API price lists, including a cheapest-API page that leads with $49 a month. Its claim is scoped: the lowest published price for a managed number reserved for one customer that can send the first message.
Those lists put shared numbers and tools that run on your own hardware in a second table. Claw Messenger is not in either table. It belongs in the shared one: $5 a month for 250 messages, $15 for 2,000, with the agent able to text registered contacts first.
So both statements can be true. $49 is ZeroSettle's price for a number of your own. $5 is Claw Messenger's price for a shared one.
When ZeroSettle is the better pick
The number is part of your brand. Customers save it, see your business name and photo, and expect the same number every time.
You run large group chats or a CRM workflow. ZeroSettle supports groups of up to 31 and lists HubSpot, Salesforce, and Close.
You need compliance paperwork. Enterprise lists SOC 2, a DPA, and security reviews. Claw Messenger makes no public compliance claim.
You want a hosted MCP server or hosted AI replies. ZeroSettle offers both. Claw Messenger's MCP server runs on your side.
When Claw Messenger fits better
The budget is small. A single-agent thread costs $5 a month. Even the Pro plan, at $50 for 15,000 messages, is about the price of one ZeroSettle number.
Some contacts are on Android. Claw Messenger falls back to RCS or SMS. ZeroSettle returns an error for numbers not on iMessage unless your account is in its SMS pilot.
Your agent runs on a framework. OpenClaw, Hermes, n8n, LangChain, and CrewAI have ready packages, and replies arrive over a WebSocket with no webhook to host. See the quickstart.
Claw Messenger only routes inbound messages from numbers you register or pair, so it suits known contacts, not a public business line.
Questions buyers ask
How much does ZeroSettle's iMessage API cost? ZeroSettle Pro costs $49 a month for one iMessage number reserved for your account, with no setup fee and a 30-day money-back guarantee. Growth starts at $199 a month. Enterprise is custom. Prices checked 6 November 2026.
Is Claw Messenger cheaper than ZeroSettle? Yes, by monthly price. Claw Messenger starts at $5 a month for 250 messages and its top self-serve plan is $50 for 15,000. The difference is the number: Claw Messenger's self-serve plans send from a number shared across accounts, while ZeroSettle's $49 buys a number reserved for you.
What is the most affordable iMessage API? It depends on who texts first and whose number it is. Photon and Inkbox have $0 plans where the person texts your agent first. Claw Messenger is $5 a month and lets the agent text a registered contact first, on a shared number. ZeroSettle Pro is $49 a month for a number reserved for you that can text first.
Does ZeroSettle fall back to SMS for Android users? Not by default. ZeroSettle's iMessage API page says a first message to someone not on iMessage returns a not_on_imessage error, and its docs describe an SMS pilot for enabled accounts. Claw Messenger falls back to RCS or SMS automatically on every plan.
Which one has a hosted MCP server? ZeroSettle publishes a remote MCP server. Claw Messenger publishes an MCP server package you run with npx; it does not host one.
