What it does

A live search on Google or YouTube, from the country and language you name, returned as ranked results with title, URL and snippet — the raw material for rank tracking, competitor discovery and content research. The cost scales with the number of results asked for.

When to use it

A weekly rank report; checking whether a page you published is indexed; feeding FABLS a topic.

Errors

Every error answers with the same envelope: an HTTP status, a machine code and a sentence.

400The body or a parameter failed validation. The details array names the field.
401No key, a revoked key or a wrong header. Send x-api-key.
402The wallet cannot cover this call. Top up or wait for the monthly grant.
404The resource does not exist, or it is not yours. Both answer identically and cost nothing.
429Over the per-minute quota of your tier. Back off and retry.
5xxUpstream refused or timed out. The call is not billed.

Cost and limits

This operation costs from 60 tokens. A call that fails is never billed. Every account gets 1000 free tokens a month; paid balances never expire. 60 tokens per page of results actually fetched. A page holds up to 10 results, so respSize 10 costs 60 tokens and respSize 100 costs up to 600. Available on the PRO and Enterprise plans: this operation spends castomAPI's own keys or quota. A key on the free plan is refused with 403 and is not billed.

Questions

What does Run a live Google search cost?

from 60 tokens per successful call, debited from your wallet after the response. Failed calls are free. Every account receives 1000 free tokens a month. 60 tokens per page of results actually fetched. A page holds up to 10 results, so respSize 10 costs 60 tokens and respSize 100 costs up to 600.

How do I authenticate?

Send your key in the x-api-key header. One key covers every metered endpoint; there is nothing to enable per endpoint.

Can I send an Authorization: Bearer token instead?

Not for a metered endpoint — those take the x-api-key header and nothing else. Bearer tokens belong to the account side: the dashboard and account APIs accept a JWT session, and castomapi-auth issues those through a standard OAuth2 handshake, with authorization code, client credentials and refresh grants. The auth service page covers it.

What are the limits?

10 requests a minute per IP with no key at all, 60 a minute on the free tier, 300 on Pro, 1200 on Enterprise. Above the no-key tier the quota is per account, across every endpoint.
