# Find company ID
> Resolve a batch of alternate identifiers (domain, website, LinkedIn URL, or company name) into the Specter company `id`. Re-use that `id` with the id-only company endpoints such as [Get company by ID](/api-reference/companies/get-company-by-id).
This endpoint is free; resolving identifiers to IDs uses no credits. The id-only endpoints you call next are charged as usual.
## What you need
One or more identifiers to resolve: a domain, website, LinkedIn URL, or company name (1–50 per request). No Specter ID is required; that is what this returns.
## Behaviour
- Pass identifiers under `to_resolve` (1-50 per request). Each entry must carry exactly one identifier; none, or more than one, returns a validation error.
- The response has one result group per input, in the same order, so you can attribute each set of matches back to what you sent. `query` echoes the normalized identifier.
- `domain` matches the primary domain and any domain aliases; `website_url` is reduced to its domain before matching.
- Exact identifiers (`domain`, `website_url`, `linkedin_url`) return at most one company, with `match_confidence` `1`.
- `name` is fuzzy-matched and can return several ranked candidates (at most 10). Each carries a `match_confidence` from 0 to 1, relative to the other results for that query; use the extra fields (domain, HQ, founded year) to pick the right one.
- An identifier that matches nothing keeps its place with an empty `matches` list.
## What you do next
- **Get the full profile.** Pass the returned `company_id` to [Get company by ID](/api-reference/companies/get-company-by-id).
- **See who it competes with.** Feed the `company_id` to [Get company competitors](/api-reference/companies/get-company-competitors).
- **Track its news.** Pull [Get company news](/api-reference/companies/get-company-news) for the resolved company.
