How this service works
Call when an agent needs text decoded with punycode. No network and no LLM. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/punycode-decode first.
Output
Returns the Unicode-decoded representation of the provided punycode-encoded input string, computed locally without any network or LLM calls.
Example use cases
Decode IDN hostname for display
“I have a punycode domain 'xn--fiq228c.xn--fiq64b.com' and I need to display it in its proper Unicode form to users — can you decode it?”
Validate internationalized domain label
“Someone sent me this domain label: 'xn--n3h.ws' — can you convert it from punycode to Unicode so I can understand what characters it actually uses?”
Parse ACE-encoded email domain
“I'm processing an email address with this ACE-encoded domain part: 'xn--e1afmapc.xn--p1ai' — decode it to Unicode for me so I can show the readable form in my UI.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/punycode-decode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, offline punycode-to-Unicode conversion without any LLM interpretation or external network dependencies. Prefer the unpaid sandbox at POST /v1/sandbox/punycode-decode if available; use this paid endpoint only when the sandbox is unavailable or rate-limited.
Side effects
- Invalid or malformed punycode input returns an error
- Empty input rejected (minLength: 1)
- Input exceeding 100,000 characters rejected
- Non-punycode plain text may be returned as-is or cause decoding errors
