      "top": 10

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "content": [

        "type": "text",
        "text": "{\"data\":[]}"
      }
    ]
  }
}

Free vs paid results

On Free a series keeps its app identity if it held any position in 1–10 during the window. Other series have locked identities while their position lines remain. Paid plans unlock identities.

Paid access does not fill coverage gaps or unknown values. Returned plan metadata and lock notes explain redaction where applicable. Read the full Free data policy.

Rate limits and usage credit

Plan	Calls per tool / day	All tools / week
Free	5	50
Basic	100	700
Pro	300	2,500

Days reset at 00:00 UTC. The combined ISO week resets Monday at 00:00 UTC. Every served tool call counts, including cached reads. Failed or refused calls are released along with any charge. Compare plans.

After either allowance, Basic and Pro can opt in to pay $0.02 in usage credit per call to get_keyword_rank_history. A call exceeding both windows is charged once. Free is refused past its allowances; paid plans without opt-in or enough credit are also refused with HTTP 402 / JSON-RPC -32004.

Credential request throttles and, for live keyword work, store-work throttles also apply. Follow retry instructions in the error reference.
