1,000 name lookups/mo

Messy names in, clean domains out.

Case, accents, punctuation and legal suffixes don't matter, and the index answers in milliseconds.

  1. Ranked, with a confidence score

    One result per domain, scored 0 to 1, and only the first can reach 0.8.

  2. Verified live when the index is unsure

    With live=true, a candidate's homepage has to call itself by the name you asked for.

  3. Fast enough for a search box

    Partial names complete, so stri returns Stripe and the call can sit behind typeahead.

What teams build with the Resolve API

  • CRM imports

    Turn a spreadsheet of company names into domains you can enrich, de-duplicate and match against.

  • Company autocomplete

    Power a company picker that suggests the right brand, and its domain, as the user types.

  • Signup enrichment

    Resolve the company someone typed into a form, then pull its brand and profile from the domain.

  • Agent tool calls

    Let an agent go from a name in a conversation to a URL every other endpoint can take.

1 credit per name lookup

A live lookup costs 3 credits, and only runs when you ask for one and the index is not confident. A lookup that matches nothing is free. Every plan unlocks every endpoint, failed requests are free, and requests pause at your limit rather than billing past it.
