Q I'm getting a 402 "Insufficient Funds" error, but my dashboard shows credits available. What's wrong?
A This is the most common issue new customers hit. It typically means your API key hasn't been fully linked to your credits yet — this can happen right after purchase or after a plan change. Wait a few minutes and try again. If the error persists after 10 minutes, reply to this email and we'll fix it immediately.
Q I'm getting a 404 "Method not supported" error. What am I doing wrong?
A The Data API uses a different endpoint structure than the standard SE Ranking Project API. If you're seeing 404s, check that you're using Data API-specific endpoints from our documentation.
Q I hit a rate limit while testing. How do I find out what limits apply to my plan?
A Rate limits vary by plan and can be hit quickly when testing at scale. Your plan's limits are listed in the documentation. We recommend checking them before running any bulk queries so you can pace your requests accordingly.
Q Where do I find location IDs for SERP endpoints?
A SERP endpoints require a location_id parameter. The full list of location IDs, searchable by country name, is available in the documentation. This is one of the most-asked setup questions, so we recommend bookmarking it.
Q How do I know how many credits each API call costs?
A Credit costs vary by endpoint. Before running large jobs, check the per-endpoint pricing in the documentation to estimate your usage. You can monitor your running credit balance in the API Dashboard at any time.
