RDAPify

Unified, Secure, High-Performance RDAP Client

Website · Docs · API Reference · Playground

RDAPify is a production-grade RDAP client ecosystem built on a Rust engine. It queries domain, IP, ASN, nameserver, and entity registration data — replacing legacy WHOIS with a structured, standards-compliant (RFC 7483) approach built for security, observability, and scale.

# Rust
cargo add rdapify

# Node.js (native binding)
npm install rdapify-nd

# Python (native binding)
pip install rdapify-py

npm install @rdapify/pro

Rust:

use rdapify::RdapClient;

#[tokio::main]
async fn main() -> rdapify::Result<()> {
    let client = RdapClient::new()?;
    let domain = client.domain("example.com").await?;
    println!("{:?}", domain.registrar);
    Ok(())
}

Node.js (rdapify-nd):

const { domain, ip, asn } = require('rdapify-nd');

const d = await domain('example.com');
console.log(d.registrar?.name, d.ldhName);

const i = await ip('8.8.8.8');
console.log(i.name, i.country);

Python (rdapify-py):

import rdapify_py as rdap

d = rdap.domain("example.com")
print(d["registrar"]["name"], d["ldhName"])

CLI:

cargo install rdapify --features cli
rdapify domain example.com
rdapify ip 8.8.8.8
rdapify asn AS15169

No configuration needed — RDAPClient selects the right fetcher automatically.

rdapify follows a hexagonal (Ports & Adapters) architecture:

Query → Validate → Normalize → Cache? → Bootstrap → Fetch → Normalize → Redact PII → Cache → Return

Inner layers (core/, shared/) never depend on outer layers (infrastructure/). The plugin interface allows @rdapify/pro to attach to RDAPClient without modifying the core.

• Core RDAP client — domain, IP, ASN, nameserver, entity
• IANA Bootstrap (RFC 9224) — automatic server discovery
• SSRF protection
• In-memory cache (DashMap, lock-free)
• Retry with exponential back-off
• Node.js binding (rdapify-nd via napi-rs)
• Python binding (rdapify-py via PyO3)
• CLI tool
• Async Python binding (Q2 2026)
• WASM target (Q3 2026)

• License validation (online-first, signed local cache)
• Bulk monitoring & change detection
• Analytics & reporting
• Webhook integrations (Slack, Discord, Teams)
• Export (CSV, JSON)
• Web dashboard (Q2 2026)
• Terraform provider (Q4 2026)

Target: v1.0.0 — after February 2027

• SSRF protection blocks all RFC 1918, loopback, and reserved ranges
• Input validation on all query types (domain, IP, ASN, handle)
• No credentials or PII logged — audit log is redacted by default
