Send a one-time SMS code to a US phone number and check the submitted six-digit code.

## Call it directly from your coding agent

Verification is available directly through [Sapiom Cloud MCP](/integration/mcp-servers/remote.md) in Claude Code or Codex:

1. Call `sapiom_verify_send` with a `+1` E.164 phone number and retain the returned verification ID.
2. Call `sapiom_verify_check` with that verification ID and the six-digit code supplied by the user.

Use `tool_discover` or `tools/list` for the current schema. Do not log the verification code or treat a send response as proof that the user controls the number; only the check operation establishes that result.

## Typed-client boundary

The current `@sapiom/tools` client has no phone-verification namespace. There is no supported `ctx.sapiom.verify` or `createClient().verify` method; use Sapiom Cloud MCP for this surface.

> Verification sends are metered. Check the signed-in catalog for current price
  availability before initiating a send.
