FAQ

How fresh is the data?
Google Trends updates daily; the series covers the trailing 12 months.

Which regions are supported?
Any 2-letter geo code Google Trends supports, or worldwide when omitted.

What if Google blocks the request?
The endpoint falls back to web-search-based trend synthesis so it never returns empty.

Do I need an API key?
No. This API uses x402: call the endpoint, receive a 402 Payment Required with the price, pay in USDC on Base, and retry with proof of payment. No signup, no API key, no account.

Which facilitators are supported?
Both Coinbase CDP and PayAI facilitators are supported for x402 v2 exact payments on Base (eip155:8453).

What if my payment is too low?
The facilitator verifies the on-chain amount against the price. If underpaid, you get 402 again; pay the full amount and retry.
