01

Pipeline pricing

Bloom → DNS → RDAP → WHOIS. Each query stops at the first definitive answer, and you're billed at that method's rate — never the steps that came before it.

02

Bulk, not batched

Send a million domains in a single request. Results stream back as the pipeline resolves them. No rate-limit tax, no orchestration plumbing.

03

Parsed WHOIS + history

Registrant, registrar, dates, status flags — normalized across TLDs. Every query snapshotted permanently, so you can diff ownership changes over time.

04

AI name generation

Describe the product. Get candidate names with available TLDs, piped directly through the availability checker. No copying and pasting.

05

Brand monitoring

Watch the global registration firehose for lookalikes. Get paged the moment acme-support-billing.com shows up — before the phishing email does.

06

SDKs & CLI

Node, Python, Go, Rust. A single-binary CLI for pipelines. Webhooks for new-registration and status-change events, and direct BigQuery / Snowflake exports.

Pricing · pay as you go

You pay for the resolving method, not the pipeline.

Every query flows through Bloom → DNS → RDAP → WHOIS and stops at the first definitive answer. If Bloom resolved it, you pay the Bloom rate — the intermediate steps that were inconclusive are never charged. Customers who want raw WHOIS for every domain can skip straight to WHOIS.
