x-api-token
string
header
required

API Key to authenticate requests.

To access the API, include your API key in the x-api-token header. To obtain your API key, complete the form or contact us directly.

Body

application/json

Common parameters shared across standard endpoints.

q
string

The keyword(s) to search for in articles. Query syntax supports logical operators (AND, OR, NOT) and wildcards:

  • For exact phrases, use escaped quotes: \"technology news\"
  • Use * for wildcards: technolog* (cannot start with *)
  • Use + to include and - to exclude: +Apple, -Google
  • Boolean operators: technology AND (Apple OR Microsoft) NOT Google
  • Forbidden characters: [ ] / \\ : ^ and URL-encoded equivalents

Note: The API automatically inserts AND operators between standalone terms, so strings like "machine learning" become "machine AND learning". To avoid syntax errors (especially in queries with OR operators), use literal escape "\"machine learning\"".

For detailed syntax rules, see Advanced querying.

Example:

"\"supply chain\" AND Amazon NOT China"

  • ai_extracted: Identifies locations through AI-based content analysis. Requires AI Extraction plan.

For detailed information, see Location detection methods.

Available options:
dedicated_source,
local_section,
regional_source,
standard_format,
proximity_mention,
ai_extracted
Example:
lang

The language(s) of the search. The only accepted format is the two-letter ISO 639-1 code. To select multiple languages, use a comma-separated string or an array of strings.

To learn more, see Enumerated parameters > Language.

Example:
countries

The countries where the news publisher is located. The accepted format is the two-letter ISO 3166-1 alpha-2 code. To select multiple countries, use a comma-separated string or an array of strings.

To learn more, see Enumerated parameters > Country.

Example:
is_paid_content
boolean

Filters articles by content completeness.

If false, returns only articles for which full-text content is publicly available. If true, returns all indexed articles, including those where only partial content is publicly available (e.g., headlines, summaries, or preview paragraphs from paywalled sources).

Note: NewsCatcher indexes content that is publicly accessible and available for crawling in accordance with publisher access controls (e.g., robots.txt and similar mechanisms). For paywalled sources, only content that publishers make publicly available (such as headlines, summaries, or preview text) is indexed. NewsCatcher does not bypass paywalls, authentication systems, or other technical access restrictions.

Example:

false
