Billing
Both endpoints use the same per-request pricing. Each billable request counts once, regardless of how many results it returns.
Billing fields
Every response includes billed, which tells you whether the request counted, and billing_source, which identifies prepaid balance or your monthly Free allowance.
| Field | Type | Description |
|---|---|---|
billed | boolean | True when the request consumed account usage; false when it did not. |
billing_source | string | null | When billed is true, free means monthly Free allowance was consumed and prepaid means balance was deducted; null when billed is false. |
What is billed
Invalid requests, authentication failures and rate-limit rejections are not billed.
Requests use prepaid balance while balance is available and otherwise the monthly Free allowance.
Rates, volume tiers and per-plan rate limits are published on the pricing page.
