How this service works
Call when an agent needs text encoded with punycode. No network and no LLM. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/punycode-encode first.
Output
Returns the punycode-encoded ASCII-compatible representation of the input text string, suitable for use in DNS labels, domain names, or other contexts requiring ACE encoding.
Example use cases
Internationalized domain name DNS resolution
“I need to punycode-encode 'bücher.example' so I can look it up in the DNS system — can you convert it to its ASCII-compatible form?”
Emoji domain to ACE conversion
“Convert the emoji domain '🍕.ws' to its punycode representation so I can register it with a domain registrar.”
Encoding Arabic hostname for network config
“Punycode-encode 'مثال.إختبار' for me — I need the ASCII-compatible version to put into a server configuration file.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/punycode-encode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, offline punycode encoding of a Unicode string without relying on an LLM or external network call. Prefer this over implementing punycode logic inline when working in a sandboxed agent environment. Note: the description recommends trying an unpaid POST /v1/sandbox/punycode-encode endpoint first to avoid the $0.001 USDC charge.
Side effects
- Empty or missing 'text' field returns validation error
- Input exceeding 100,000 character limit rejected
- Network/service unavailability returns HTTP 5xx
- Payment failure or insufficient USDC balance returns HTTP 402
