Resolve a company to its official record with one call

A company name in a form field is not an identity. "Equinor" could be the listed group, a subsidiary or a toastmasters club that shares the address. Before an agent enriches, scores or onboards anything, it needs the legal entity from the official register.

One request

curl "https://api.ambolt.dev/v1/entity-resolve?query=Equinor%20ASA&country=NO&free=1"

The answer is the best match plus candidates, each with the register it came from:

{
  "matched": true,
  "bestMatch": {
    "country": "NO",
    "registry": "Brønnøysundregistrene (Enhetsregisteret)",
    "registryId": "923609016",
    "name": "EQUINOR ASA",
    "legalForm": "Allmennaksjeselskap",
    "status": "active",
    "incorporationDate": "1972-09-18",
    "lei": "OW6OFBNCKXC4US5C7523",
    "sourceUrl": "https://data.brreg.no/enhetsregisteret/api/enheter/923609016",
    "licence": "NLOD 2.0",
    "matchScore": 100,
    "matchReason": "exact normalised name"
  }
}

Recorded 2026-10-03; fields trimmed. The record carries sourceUrl and licence, so you can show where a fact came from and under which terms it may be reused.

What goes in

A company name, a website domain, a registry number, an LEI or a VAT number. The tool works out which one it got.

Where it looks

The official registers of Norway, Finland, Czechia, Slovakia, France and the United Kingdom, Poland by KRS number, and any company with an LEI worldwide through GLEIF. Each register is queried directly; each record names its licence.

What it does not do

It returns companies only: no officers, directors or owners, and no sole traders (their names are personal data).
Scores under 90 are suggestions. Check the linked source record before acting on them.
It does not replace an official extract or your own KYB process.

Using it

As an MCP tool: add https://api.ambolt.dev/mcp to your agent and call entity_resolve (free, 30 requests a minute).
As an HTTP endpoint: a price in the 402 answer, paid in USDC with an x402 client. Add free=1 for one free call per tool and IP address per day.
As an Apify Actor with batches of up to 100.

See the EntityResolve page for inputs, sources and prices.

Try it free: Company register lookup runs the same call in your browser (one free check per tool and IP address per day). API reference
