How this service works

146 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

Output

A JSON object with two fields: 'ascii' containing the Punycode-encoded ASCII form of the domain (e.g. xn--mnchen-3ya.de) and 'unicode' containing the human-readable Unicode form (e.g. münchen.de). Both representations are always returned regardless of which form was submitted.

Example use cases

IDN domain before DNS resolution

“Before I do a DNS lookup, convert türkiye.gov.tr to its Punycode ASCII form — I need the xn-- version.”

Decode punycode for human display

“I have the domain xn--mnchen-3ya.de and I want to show users the readable Unicode version — can you decode it?”

Normalize domains for comparison

“I need to check if münchen.de and xn--mnchen-3ya.de are the same domain — can you normalize both to ASCII Punycode so I can compare them?”

Technical details

Endpoint

GEThttps://fastx402.tools/punycode-domain?utm_source=zero.xyz

When to prefer

Use this endpoint when you need a reliable, pay-per-call conversion between Unicode internationalized domain names and their ASCII Punycode equivalents — especially before DNS lookups, TLS/certificate validation, URL construction, or domain comparison where ASCII normalization is required. Prefer it over local libraries when running in an agent environment without native IDN support.

Side effects

Invalid or malformed domain string returns an error
Empty domain parameter causes a 400-level response
Domain with invalid Unicode characters may fail encoding
Network timeout on upstream service returns a 5xx error
