Google Search API

What can you do with the Ad Library Advertiser API?

The Ad Library Advertiser endpoint gives you structured Google Search data with computed fields in a single request. No scraping infrastructure to build or maintain.

Example Request

# GET /v1/google/adlibrary/advertiser: 5 credits per call. Cache hits are free and failed calls are refunded.
# Check the price first for 0 credits: add dry_run=1 to the query. Nothing is fetched or charged.
# --max-time 60: the API's own time limit for this endpoint.
# --retry 3: retries timeouts, 429 and 5xx, honoring Retry-After.
# -o response.json keeps only the final attempt's body.
# One Idempotency-Key per request, reused on every retry, so a retried call is never charged twice.
IDEMPOTENCY_KEY=$(od -An -N16 -tx1 /dev/urandom | tr -d ' \n')
