x402-Werkzeuge für autonome Agenten.

Output

Returns the parsed phone number in multiple standardized formats: E.164 (e.g. +4930123456), international format (e.g. +49 30 123456), national format (e.g. 030 123456), and tel-URI (e.g. tel:+4930123456). Also returns the detected country calling code, area/network prefix, subscriber number, and for German numbers the number type (Festnetz/landline, Mobilfunk/mobile, or Sonderrufnummer/special) along with any associated cost information.

Example use cases

CRM phone number normalization

“I have this customer phone number '0151 23456789' from a German contact form — can you parse it, confirm it's a mobile number, and give me the E.164 and tel-URI formats so I can store it properly in our CRM?”

Detecting premium rate numbers before dialing

“Before I dial '0900 123456', can you check whether that's a German special-rate or premium number and let me know if there are any cost warnings associated with it?”

Normalizing international number without country prefix

“I have the number '+44 20 7946 0958' in my contacts — can you parse it, detect the country code, and give me back the proper international and national formats?”

When to prefer

Choose this endpoint when you need reliable, multi-format phone number normalization with specific support for German number type classification (landline vs. mobile vs. special rate with cost hints). It is particularly suited for German-market applications where distinguishing Festnetz, Mobilfunk, and Sonderrufnummern matters. Prefer it over generic phone libraries when you need E.164, international, national, and tel-URI outputs in one call, or when handling national-format German numbers that lack a country prefix.

Side effects

Unrecognizable number format — returns error if the input cannot be parsed as any valid phone number pattern
Unknown country prefix — if the number's calling code is not among the 150 supported prefixes, country detection fails
Ambiguous national number without default_country — numbers without a country prefix may be misclassified if default_country is not set
Too short or malformed input — very short strings or non-numeric input may return a parse error
