How this service works
Paste malformed JSON from ChatGPT, Claude or any model and get it repaired in your browser. Fixes code fences, trailing commas, single quotes, unquoted keys, Python True/False/None, comments and truncated output — and names every repair it made. Free, no signup, nothing uploaded.
Output
A JSON object with fields: ok (boolean), found (boolean), domain (string), registrar (string), nameservers (array of strings), status (array of status strings like 'client transfer prohibited'), dnssec.signed (boolean), and events containing ISO-8601 registration and expiration timestamps.
Example use cases
Domain expiry monitoring for portfolio
“Check when stripe.com expires and who it's registered with — I need to know the registrar and expiration date so I can flag it if it's coming up soon.”
Due diligence on a potential acquisition
“Pull the WHOIS registration details for acmecorp.io — I want the registrar, nameservers, registration date, current status flags, and whether DNSSEC is enabled.”
Verify domain ownership before outreach
“Who is the registrar for mozilla.org and is there a client transfer prohibited status on it? Also tell me the nameservers.”

Endpoint
POSThttps://penniless-json-repair.sjaman.workers.dev/domain/whois?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable WHOIS/RDAP data without parsing raw WHOIS text. It is ideal for domain expiry checks, registrar lookups, nameserver verification, DNSSEC audits, and due-diligence workflows where a clean JSON response is required. At $0.001 USDC per call via x402 micropayments, it is cost-effective for high-volume domain intelligence tasks. Prefer this over scraping WHOIS directly when deterministic output and no external AI dependencies are required.
Side effects
- Domain not found in RDAP/WHOIS — returns ok:true, found:false
- Invalid or malformed domain name input — likely returns an error response
- Registry temporarily unavailable — network-level or upstream RDAP registry timeout
- TLD not supported by RDAP — some ccTLDs may not have RDAP coverage
- Rate limiting from upstream RDAP registries causing delayed or failed responses
