# Ultimate Parent

Resolve the commercial parent of a company: the operating group it is sold to and routed under. Submit a company (name + website, optional country) — the website anchors the resolution — and the API returns a job\_id you poll until the result is ready. The response includes the commercial parent, the full ownership chain with passive holding entities flagged `is_discarded`, the ultimate financial parent when a financial owner such as a fund sits above the operating group, GLEIF Legal Entity Identifier (LEI) data for each entity where a match is found, and the resolver's reasoning with its cited source URL.

## Find & validate ultimate parent

> Resolve a company's ultimate parent from one of its subsidiaries, brands or divisions: send \`company\_name\` and \`website\`, both required. The parent returned is the \*\*commercial parent\*\*: the operating group the company is sold to and routed under. Passive holding entities set aside on the way up are flagged \`is\_discarded\` in the ownership chain, and when a financial owner such as a fund sits above the operating group it is returned separately as \`ultimate\_financial\_parent\`. The result also carries the full ownership chain, the relationship type and a confidence score; each entity carries GLEIF metadata in \`lei\_data\` when a match is found, \`null\` when none is.\
> \
> The resolution is anchored on the company's website, not on its name alone: the website binds the name to one specific entity and seeds the search. Ownership is resolved from a live web search plus GLEIF/LEI lookups, not from a static database.\
> \
> Async: poll \`getUltimateParentResult\` with the returned \`job\_id\`.\
> \
> The company name, website and country you supply are sent to Delpha's AI providers, which search the web; the parent found is checked against GLEIF's public LEI register.\
> \
> A live-mode call reserves credits and creates a job record retained for 10 days; unless your team has set resolution retention to 0, the call and its result are also recorded in your team's resolution history for the window your team configured (up to 30 days on the free tier, 180 on a paid plan). Re-submitting the same input starts a new job and a new charge, unless the request carries an \`Idempotency-Key\` already used with the same body within the last 24 hours — that returns the original \`job\_id\` and reserves nothing. Test-mode calls are answered from the published fixture table and reserve nothing — see the API documentation's \*\*Test mode\*\* section.

## Get ultimate-parent result

> Fetch the result of a previously submitted \`submitUltimateParent\` job by \`job\_id\`. The resolver walks ownership upward from the queried company and returns as \`ultimate\_parent\` the \*\*commercial parent\*\* — the operating group the company is sold to and routed under, not necessarily the top legal owner. Passive holding entities set aside on the way up stay in \`ownership\_chain\` flagged \`is\_discarded\`; when a financial owner such as a fund sits above the operating group, it is returned separately as \`ultimate\_financial\_parent\`.\
> \
> Top-level \`result\` fields: \`ultimate\_parent\` (\`CompanyEntity\`), \`relationship\_type\` (\`Wholly Owned\` / \`Joint Venture\` / \`Member Firm/Franchise\` / \`Portfolio Company\` / \`Brand/Division\` / \`Independent\`), \`confidence\` (a number in \`\[0, 1]\` reported by the resolver), \`comment\`, \`source\_url\` (cited URL, may be \`null\`), \`ownership\_chain\` (\*\*bottom-up\*\* array; index 0 is the queried company), and \`ultimate\_financial\_parent\` (\`CompanyEntity\` or \`null\`). Each \`CompanyEntity\` carries \`legal\_name\`, \`commercial\_name\`, \`country\`, \`website\`, \`website\_validated\`, \`is\_ultimate\_financial\_parent\`, \`is\_discarded\` and \`lei\_data\` (GLEIF metadata or \`null\`).\
> \
> Reading a result starts no work and adds no charge, but it finalizes the job's accounting once: the job's charge is settled when its result is first delivered, and refunded when the job failed, exceeded its time limit or produced no usable result — a job past its time limit is marked failed by that read. Repeating the call returns the same answer and never charges again.

## Submit a batch of ultimate-parent resolution items

> Submit 1..100 ultimate-parent resolution items for asynchronous batch processing as ONE job (never a per-item fan-out). Returns a \`job\_id\` immediately (202); poll \`GET /v1/ultimate/batch/{job\_id}\` for status and results. Each item follows \`UltimateSubmitInput\`; see that component for its fields. It uses the runtime validation of \`POST /v1/ultimate\`. A payload with 0 items or more than 100 is rejected with 422.\
> \
> A live-mode call reserves credits and creates a job record retained for 10 days; unless your team has set resolution retention to 0, the call and its result are also recorded in your team's resolution history for the window your team configured (up to 30 days on the free tier, 180 on a paid plan). Re-submitting the same input starts a new job and a new charge, unless the request carries an \`Idempotency-Key\` already used with the same body within the last 24 hours — that returns the original \`job\_id\` and reserves nothing. Test-mode calls are answered from the published fixture table and reserve nothing — see the API documentation's \*\*Test mode\*\* section.

## Get ultimate-parent resolution batch job status

> Poll a batch of ultimate-parent resolution items submitted via \`POST /v1/ultimate/batch\`. 202 while running (with \`item\_count\`/\`processed\_count\` progress); 200 once SUCCEEDED (with \`counts\`, a presigned \`result\_url\`, and \`result\_data\` inlined when <=1MB); 409 if the credit reservation expired before delivery (resubmit); 500 if the job failed; 504 past the 24h ceiling.\
> \
> Reading a result starts no work and adds no charge, but it finalizes the job's accounting once: the job's charge is settled when its result is first delivered, and refunded when the job failed, exceeded its time limit or produced no usable result — a job past its time limit is marked failed by that read. Repeating the call returns the same answer and never charges again.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.delpha.io/delpha-api-and-mcp/api/ultimate-parent.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
