# google.keyword_volume

**beta** **35 credits** **needs a pack**

Google search volume for a keyword in a country and language: average monthly searches, last 12 months, CPC, competition and keyword difficulty.

`GET /v1/google/keyword_volume`

> [!NOTE] **Beta.** This endpoint has not yet been verified against the live source, so fields may be missing or differ until it becomes stable. Failed calls are refunded.

> [!NOTE] **Needs a pack.** Needs a purchased pack and a verified email; free credits do not reach this endpoint. See [pricing](https://onekey.dev/pricing).

## What you get

A list of Google results in Onekey's unified shape, in `data` (an array). An empty array is a normal, successful answer and is charged like any other; a source that reports "nothing found" as an error returns a free `404 not_found` instead.

## What it costs

- **35 credits** for a fresh fetch, charged only when it succeeds.
- **Free when served from cache (0.2 credit for a cached response over 100 KB).**
- **Free** if the request is invalid (never charged) or the source fails or reports not found (refunded).

## Field mapping

How this endpoint's source fields become Onekey's [unified schema](https://onekey.dev/docs/schema.md). Fields the source lacks come back as `null`.

| Source path | Onekey field | Transform |
| --- | --- | --- |
| `keyword` | `content.title` | - |
| `keyword_info.search_volume` | `ext.searchVolume` | `toNumber` |
| `keyword_info.monthly_searches` | `ext.monthlySearches` | - |
| `keyword_info.cpc` | `ext.cpcUsd` | `toNumber` |
| `keyword_info.competition` | `ext.competition` | `toNumber` |
| `keyword_info.competition_level` | `ext.competitionLevel` | - |
| `keyword_properties.keyword_difficulty` | `ext.keywordDifficulty` | `toNumber` |
| `location_code` | `ext.locationCode` | `toNumber` |
| `language_code` | `ext.languageCode` | - |

## Caching and freshness

- Fresh for about 1 day. Repeat calls in that window are served from cache and are free.
- Between 1 day and 7 days the cached copy is still served instantly and marked `stale: true` while Onekey refreshes it in the background.
- If the source is down when a refresh is needed, the last copy can be served for up to 7 days more (marked stale).
- A "not found" is remembered for 1 hour and is free.
- The cache is shared across all customers, which is what keeps repeat calls cheap.

## What can go wrong

| Status | Code | What to do |
| --- | --- | --- |
| 401 | `unauthorized` | Check the `x-api-key` header. |
| 402 | `insufficient_credits` | [Add credits](https://onekey.dev/pricing); your balance must cover the price. |
| 404 | `not_found` | Unknown endpoint path. |
| 422 | `invalid_params` | Fix the parameters using the table above. Free. |
| 429 | `rate_limited` | Wait `Retry-After` seconds, then retry. |
| 502 | `upstream_error` | The source failed. Refunded; retry with backoff. |

See [Errors](https://onekey.dev/docs/errors.md) for the full list and retry guidance.
