> ## Documentation Index
> Fetch the complete documentation index at: https://docs.photon.codes/docs/llms.txt
> Use this file to discover all available pages before exploring further.

> ## Agent Instructions
> Use Stable documentation by default. Honor an explicit Beta request or a URL under /docs/beta/. If the requested version conflicts with the installed CLI package or API origin, clarify the target before writing integration code.
> Pages under /docs/beta/ document Beta; other product pages document Stable. Keep the CLI package, commands, API origin, and credentials within the selected version. State the documentation version in your answer.
> For MCP search, always pass version: Stable or version: Beta. Unfiltered search mixes both versions. For filesystem reads, keep Beta queries under /beta/ and exclude /beta/ from Stable queries; discover paths before reading them.
> The public docs base is https://photon.codes/docs. Convert MCP page paths to public URLs under that base, preserving /beta/ when present. Read https://photon.codes/docs/skill.md for version selection and https://photon.codes/docs/llms.txt for the version indexes.

# Purchase SMS number

> Buys one US local number from the provider and records it as a resource with SMS enabled. Requires countryCode (US) and accepts an optional three-digit geographic areaCode. The server selects an exact matching number. Empty inventory keeps the operation running until a number is available or the caller cancels before ordering begins. Always answers 202 with an operation: the work runs behind the response, and the Location points at the operation to poll. New area-specific requests must appear in current provider coverage; discover it with GET /sms/numbers/area-codes?countryCode=US. Coverage and subscription checks run before operation creation. Billing follows delivery. Replays return the original operation without checking current coverage. The Idempotency-Key is required and permanent: repeating it returns the same operation forever, never a second number. A further number always needs a NEW key, including while others are still running. Requires the platforms:write permission bound to the project resource in the path.
