CrakSEO’s MCP servers and APIs are pay as you go. There is no subscription and no minimum deposit for data calls. You buy a pack of API credits, and each paid call deducts its price.

​
Packs

Packs are bought on the API credits tab of Indexing (/app/indexing/credits). When your balance is too low, MCP servers return an insufficient_credits error that points there. Credits don’t expire. Final pack sizes are set at launch.

​
Per-call prices

Each tool’s price per call is listed on its server page. Prices marked TBD are placeholders until launch.
  • Free: every tool on the Search Console MCP, IndexNow submission and index status checks on the URL Indexing MCP.
  • Paid Google submission is priced per accepted URL, shown in an exact quote and charged only after the account owner approves it.
  • Calls that fail with an error are not charged.
  • Repeated identical data requests may be served from a short-lived cache at the same price.

​
Pay per call without an account

Once pay-per-call is switched on (it is not live yet), agents can call the REST endpoints without a CrakSEO account by paying for each call with x402 or Stripe’s Machine Payments Protocol (MPP):
  • x402: USDC on Base. The agent’s wallet signs a payment authorization for the quoted amount.
  • MPP: stablecoins on Tempo, or a card through a shared payment token from an agent wallet such as Link. Card payments are only offered for calls of $0.50 or more.
A call without an API key or payment gets HTTP 402 Payment Required with the exact price, fixed before the call (about three times the API credits price, at least $0.01). The payment is only taken after the data comes back. If the call fails, you are not charged, and each payment pays for one call only. The REST hostnames are: Each host serves its tool list at / and one tool per path, for example https://serp.crakseo.com/get_google_serp. These hostnames go live once their DNS records are in place; until then, use the MCP servers. API credits pay for data calls and paid indexing. Link credits pay for placements in the Link Network and only come with that plan. The two balances are separate, and buying one never changes the other or your subscription.

​
Refunds

Unused API credits can be refunded within the window stated in the terms. Credits already spent on calls aren’t refundable.
