How this service works
Phone Numbers to E.164 — Turns a list of phone numbers written any way people write them into E.164 (a plus sign, the country code and the national number, digits only), one JSON object per number, using a default country the request states. Where plain models slip - the trunk 0 left in, "+44 (0)20" glued to a stray zero, Italian numbers with the leading 0 wrongly dropped, the leading 1 of a North American number kept, a made-up country for a bare local number, an extension stuck onto the numbe…
Output
Returns a JSON object containing the SKILL.md file name, full UTF-8 file content (instructions for normalizing phone numbers to E.164), the skill identifier ('phone-e164-normalize'), a SHA256 checksum of the file, a payment receipt with the settlement transaction hash, the skill version (e.g. 1.0.0), and a redownload URL and token for future free re-downloads.

Technical details
Endpoint
GEThttps://api.aiskills402.com/v1/skills/phone-e164-normalize/file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a tested, ready-to-use SKILL.md instruction file specifically for E.164 phone number normalization, and want a one-time purchase model with free re-downloads and version updates, paid in USDC via x402 micropayment on Base. Prefer this over writing custom normalization logic from scratch when you want a curated, agent-ready skill definition.
Side effects
- Payment not received or insufficient USDC balance — x402 payment required before file is delivered
- Invalid or missing HTTP method — endpoint accepts only GET or HEAD
- Network or blockchain settlement failure — receipt may show settled:false
- SHA256 mismatch on re-download — file integrity check fails
- Redownload token expired or invalid — unable to retrieve previously purchased skill
