Resolve external identifiers (LinkedIn slugs, domains, tickers, CIKs) to Particle people and companies.

Tool ID: particle_lookup_entities

Run this action

Use the TypeScript SDK for one call. Use ctx.tools.execute(...) inside a Play for durable calls, scheduled calls, or CSV processing.

import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'particle_lookup_entities',
  {
    "identifier": [
      "example_123"
    ]
  },
);

console.log(result.toolResponse.raw);

CLI

deepline tools execute particle_lookup_entities --input '{
  "identifier": [
    "example_123"
  ]
}' --json

The static output schema lacks the details for a reliable example. Use deepline describe particle_lookup_entities --json for the complete live contract.

Input reference

Resolves external identifiers — LinkedIn slugs, social handles, company domains, stock tickers, SEC CIKs, Wikidata QIDs — to the people and companies that carry them. It is the reverse of GET /v1/people/{slug}/external-links and GET /v1/companies/{id}/external-links. Pass a comma-separated identifier list (up to 100 per call). platform is optional, so a handle with no known source still resolves. A full profile URL works in place of a bare identifier and the platform is inferred from it, and the stored form is matched for you — pass satyanadella or the profile URL, not in/satyanadella. Each result echoes the input identifier and carries a matches array, because an identifier is not unique to an entity: a LinkedIn profile claimed by two duplicate person records resolves to both, and match_count reports the total. Unresolved identifiers come back with an empty matches, so a See the live schema below for the complete notes.

Name	Type	Required	Default	Details
`payload.identifier`	`array`	Yes	—	One or more external identifiers to resolve. Pass a comma-separated list to look up many at once (max 100 per call). A full profile URL works in place of a bare identifier and the platform is inferred from it. The identifier is echoed back exactly as supplied, not normalized. Minimum items: 1. Maximum items: 100.
`payload.platform`	`string`	No	—	Restrict the lookup to one platform. Optional — omit it to match the identifier on any platform, which is what you want when you hold a handle but not its source. Accepts any platform reported on the external-links endpoints plus the company identifier namespaces ‘domain’, ‘ticker’, ‘sec’ (CIK) and ‘wikidata’ (QID).
`payload.type`	`"person" \| "company"`	No	—	Restrict results to one kind of entity. Omit to search people and companies together. Allowed: `person`, `company`.

Output reference

Standard tool result payload.

Name	Type	Required	Default	Details
`result.data`	`object`	Yes	—	Provider response payload.
`result.data.results`	`array \| null`	Yes	—	One result per unique input identifier, in request order. Duplicate identifiers in the request collapse to a single result.
`result.data.results[].identifier`	`string`	Yes	—	The identifier exactly as supplied in the request, not normalized.
`result.data.results[].match_count`	`integer`	Yes	—	How many distinct entities carry this identifier. Larger than the length of ‘matches’ when more than 10 do. A count above 1 means the identifier is shared, usually by duplicate records for the same real person — 8.7% of LinkedIn identifiers are. Format: `int64`.
`result.data.results[].matches`	`array \| null`	Yes	—	The entities carrying this identifier, best first: records linked to a knowledge graph entity come before those without, then oldest first. Empty when the identifier does not resolve.
`result.data.results[].matches[].company`	`object`	No	—	—
`result.data.results[].matches[].company.description`	`string`	No	—	Short company description, when known.
`result.data.results[].matches[].company.domain`	`string`	No	—	Primary website domain (e.g. ‘nvidia.com’), when known.
`result.data.results[].matches[].company.id`	`string`	Yes	—	Company identifier (domain, slug, or encoded ID)
`result.data.results[].matches[].company.image_url`	`string`	No	—	Company logo or image URL
`result.data.results[].matches[].company.name`	`string`	Yes	—	Company name
`result.data.results[].matches[].company.slug`	`string`	No	—	Stable human-readable handle (the linked knowledge-graph slug, e.g. ‘nvidia’), when known. Companies have no slug of their own. prefer this for display and pass it (or id) to /v1/companies.
`result.data.results[].matches[].company.ticker`	`string`	No	—	Primary stock ticker symbol, when listed.
`result.data.results[].matches[].person`	`object`	No	—	—
`result.data.results[].matches[].person.description`	`string`	No	—	Short description (e.g. current role), when known.
`result.data.results[].matches[].person.id`	`string`	Yes	—	Encoded Person identifier
`result.data.results[].matches[].person.image_url`	`string`	No	—	Canonical headshot URL when one is known for the Person
`result.data.results[].matches[].person.name`	`string`	Yes	—	Display name
`result.data.results[].matches[].person.slug`	`string`	No	—	Stable human-readable handle (e.g. ‘satya-nadella’). Recommended canonical identifier on every Particle Pro person surface.
`result.data.results[].matches[].type`	`"person" \| "company"`	Yes	—	Which kind of entity matched. The corresponding field below is the one that is set. Allowed: `person`, `company`.
`result.data.results[].platforms`	`array \| null`	No	—	The platforms this identifier matched on, alphabetically. Usually one. Several when a handle is the same across platforms and no ‘platform’ filter was given. Omitted when nothing matched.
`result.meta`	`object`	No	—	Additional response metadata (status, paging).
