Allowances and costs
Search credits come from the account plan; subscriptions provide different monthly allowances.
Free access: A recurring zero-dollar plan is documented, but the account plan and remaining credits are unknown.
- The documented free plan includes 250 monthly searches and hourly throughput limits.
- The same endpoint can incur paid usage on another plan; no_payment eligibility remains unresolved.
What still needs checking
- Extract does not execute JavaScript.
- Known search-engine URLs may be routed to their dedicated engine and return a different structure.
- Personalized URLs containing api_key must remain private.
- Documentation review only; Relay did not connect, run tools or measure cost, speed or task quality.
