Brief for an AIEverything needed to call it, as text

Show the text

Use the DataXAPI endpoint meta.advertisers.search (Meta advertiser search). Find advertisers (Facebook pages) in the Meta Ad Library by name: ID, name, picture, category, page likes, the linked Instagram account. The ID is what the advertiser's ads are asked for by.
Call GET https://api.dataxapi.com/v1/meta/advertisers/search with the header "Authorization: Bearer $DATAXAPI_API_KEY". Read the key from the environment variable DATAXAPI_API_KEY; never write it into code.
Parameters:
- query (required): Name of the advertiser or brand. Example: puma.
- view: How much of each item to return. All three cost the same. Values: compact, standard (default), full.
- fields: Return only these fields. Each by its path, such as author.name.
Price: $0.0020 per call. Errors and timeouts are not charged; an empty result is charged $0.0020.
The answer is JSON: data.items holds advertiser; meta.billing.amount is what this call was charged.
Example:
curl -G "https://api.dataxapi.com/v1/meta/advertisers/search" \
  --data-urlencode "query=puma" \
  -H "Authorization: Bearer $DATAXAPI_API_KEY"
