Count Mode

You can get the total number of results matching any filter combination without consuming credits by adding count=true to your request. This returns an empty data array with full pagination metadata, including totalCount.

curl -X GET "https://www.trysignalbase.com/api/v2/signals/job-changes?count=true&positions=CEO,CTO&date_preset=last_30d" \
  -H "Authorization: Bearer YOUR_API_KEY"

Response:

{
  "success": true,
  "data": [],
  "pagination": {
    "currentPage": 1,
    "totalPages": 5,
    "totalCount": 93,
    "hasNextPage": true,
    "hasPreviousPage": false
  },
  "meta": {
    "endpoint": "signals.job-changes",
    "creditsUsed": 0
  }
}

Use count mode to preview how many results match your filters before fetching actual data. This is useful for building filter UIs, showing result counts, or validating queries — all at zero credit cost.

Authentication

All API endpoints require a Bearer token in the Authorization header.

curl -X GET "https://www.trysignalbase.com/api/v2/signals/job-changes?page=1&limit=20" \
  -H "Authorization: Bearer YOUR_API_KEY"

Matching by Company URL (Recommended)

If you know a company’s website domain or LinkedIn page, query by URL instead of by name. Name search is fuzzy and can return lookalikes (Novartis also matches Novartis UK); URL identifiers match exactly one company.

# By website domain
curl -X GET "https://www.trysignalbase.com/api/v2/signals/job-changes?company_domain=novartis.com" \
  -H "Authorization: Bearer YOUR_API_KEY"

# By LinkedIn company page
curl -X GET "https://www.trysignalbase.com/api/v2/signals/job-changes?company_linkedin_url=linkedin.com/company/novartis" \
  -H "Authorization: Bearer YOUR_API_KEY"

Accepted input formats. URL identifiers are normalized before matching, so equivalent variants return the same results:

company_domain: novartis.com, www.novartis.com, https://www.novartis.com/, https://novartis.com/any/path — scheme, www., port, path and trailing slash are ignored. Values that can’t be reduced to a domain return 400.
company_linkedin_url: linkedin.com/company/novartis, https://www.linkedin.com/company/Novartis/ — http/https, www. and trailing slash are ignored, the slug is case-insensitive. URLs that aren’t LinkedIn company pages (e.g. personal /in/ profiles) return 400.

Strict matching. When a URL identifier is provided, the API never falls back to fuzzy name matching: if no company matches, the result is empty. Identifiers combine with AND — company_domain=novartis.com&company_name=Acme returns empty because they disagree. Match confidence. Every result row includes match_confidence:

Value	Meaning
`exact`	Matched via `company_domain` or `company_linkedin_url`
`fuzzy`	Matched via `company_name` partial match only
`none`	No company identifier was part of the query

Query Parameters

Pagination

Parameter	Type	Default	Description
`page`	integer	1	Page number
`limit`	integer	20	Results per page (max: 100)

Date Filters

Parameter	Type	Description
`dateFrom`	string	Filter by date from (ISO-8601 string)
`dateTo`	string	Filter by date to (ISO-8601 string)
`date_preset`	string	Relative date shorthand — takes precedence over `dateFrom`/`dateTo`. See Date Presets

Text Search

Parameter	Type	Description
`search`	string	Free-text search across company name, industry, person name, and role

Country Filters

Parameter	Type	Description
`countries`	string	Comma-separated country codes (e.g., `US,GB,DE`). Allowlist; matches the person country or the company HQ country
`exclude_countries`	string	Comma-separated country names or codes to exclude (denylist, e.g. `China` or `CN`). A signal is excluded when either the person country or the company HQ matches; rows with an unknown country on a side are kept

Exact Match Filters

Parameter	Type	Description
`personLinkedinUrl`	string	Exact LinkedIn URL for a person (`person_linkedin_url` is accepted as an alias)
`company_linkedin_url`	string	Recommended. LinkedIn company URL (e.g. `linkedin.com/company/novartis`). Strict match — see Matching by company URL. Legacy alias: `companyLinkedinUrl`
`company_domain`	string	Recommended. Company website domain (e.g. `novartis.com`), matched via the linked company record. Strict match
`source`	string	Exact match on source: `linkedin`, `press_release`, `other`

Field-specific Search (partial match)

Parameter	Type	Description
`company_name`	string	Search by company name (partial match, fuzzy). Prefer `company_domain` or `company_linkedin_url` for strict matching
`new_role`	string	Search by new role / job title
`keyword`	string	Search by keyword tag

There is no person_name filter. For privacy (GDPR), people are queryable only by personLinkedinUrl, and personName is returned masked (first name + last initial). To locate a specific person, filter by their LinkedIn URL.

Parameter	Type	Description
`positions`	string	Comma-separated position IDs (e.g., `CEO,CTO,CFO`). See Positions
`departments`	string	Comma-separated department IDs (e.g., `marketing,engineering`). See Departments
`seniorities`	string	Comma-separated seniority IDs (e.g., `c_level,vp,director`). See Seniorities

Sorting

Parameter	Type	Default	Description
`sort_by`	string	`occurred_at`	Sort field: `occurred_at`, `discovered_at`, `person_name`, `company_name`
`sort_order`	string	`desc`	Sort direction: `asc` or `desc`
