# Strale Phone Normalize

> Strale Phone Normalize is a paid API for AI agents from api.strale.io, paid per call via x402, $0.0324/call, status unknown (last checked 2026-09-13).

Normalizes a phone number string to a standard international format, with optional country context for disambiguation

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability strale-phone-normalize-2d24a6b4
```

Example prompt: Can you normalize the phone number '070-123 45 67' to international format — it's a Swedish number, so use SE as the default country?

## When to prefer this

Choose this endpoint when you need reliable, auditable phone number normalization with cryptographic proof of each call — especially useful in compliance-sensitive pipelines, international contact management, or when processing numbers from 27+ countries. Prefer it over generic parsing libraries when you need a tamper-evident audit trail or when dealing with ambiguous local formats that benefit from explicit country context.

## Known failure modes

- Invalid or unparseable phone number string — returns error indicating the number cannot be normalized
- Missing required phone_string parameter — returns 400-level error
- Ambiguous local number without default_country — may fail to parse or return wrong country assignment
- Unsupported country code provided — may return error or fall back to best-guess parsing
- Payment failure or insufficient USDC balance — call is rejected before processing

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns the normalized phone number in international/E.164 format along with parsed components (country code, national number, etc.) and a cryptographic audit record with chain hashing for traceability.
