What this API helps you ship

Use this page as a production brief: endpoints, examples, response shape, and the workflow pieces needed to plug DomScan into your own product.

Product workflows

Embed domain checks, DNS intelligence, risk signals, or enrichment into onboarding, search, and internal tools.

Analyst automation

Replace repeated manual lookups with scheduled jobs, alerting, and reproducible investigation steps.

Clean JSON data

Use predictable fields, documented status codes, and credit costs instead of scraping provider pages.

AI and ops tooling

Feed agents, dashboards, SOAR playbooks, and CRMs through OpenAPI, SDK, Postman, or MCP.

Integration workflow

A simple path from first request to repeatable production usage.

1
Authenticate once

Send your API key with the documented header and keep requests consistent across services.

2
Query with examples

Start from the curl and HTTP samples, then map the parameters into your application code.

3
Operate and monitor

Use status codes, credit costs, and response fields to build retries, logs, and alerts.

Developer kit

Jump from this page into machine-readable docs, request collections, SDKs, or agent tooling.

Parameters and response map

Scan the inputs, output fields, and status codes before wiring the endpoint into your client.

Key Features

Ticker, ISIN or name

Look up a ticker on any exchange or on one you choose, an ISIN with its check digit verified, or a company name with legal forms such as Inc., AG or S.A. ignored.

Collisions are never hidden

When a ticker or name belongs to more than one company, every candidate is returned with its exchange and domain instead of one of them being picked for you.

Evidence and confidence

Each candidate lists its identifiers, the statements that link it to its website, the sources that agree and a confidence level.

Typeahead search

Use match=prefix to suggest companies while someone types, ranked by how closely their names match.

Example request

GET /v1/company/resolve?ticker=AAPL bash

Frequently asked questions

Where does the data come from?

From open public data: the SEC company ticker list for US-listed companies, refreshed daily, and Wikidata stock exchange listings, ISINs and official websites, refreshed weekly. Each candidate shows which of them it came from.

What happens when a ticker is used on several exchanges?

The result is unknown with the reason ticker_on_multiple_exchanges and lists every company that uses it. Send exchange, for example XNAS or Tokyo Stock Exchange, to choose one.

Does not found mean the company does not exist?

No. The sources do not cover every company or listing, so a missing identifier is reported as unknown, never as proof that it does not exist.

How many credits does it cost?

One credit per request, including unknown and ambiguous results, because the candidates are still returned.
