Steps Note that every request has a minimum cost of 50 units regardless of rows returned Add the per-row cost of each requested field - most fields cost 1 unit/row, but some premium metrics cost 5 or 10 units/row Check your plan's monthly unit budget (tier-gated, e.g. 100K for Lite up to 2M for Enterprise, shared with Ahrefs Connect/MCP usage on the same plan) Call the limits-and-usage endpoint before large batch jobs to confirm remaining balance Cache and reuse responses where possible, since cached results don't consume additional units Known gotchas Requesting many premium (5-10 unit) fields across thousands of rows can exhaust a monthly budget far faster than the row count suggests API v3 requires a Lite plan or higher - it isn't available on the cheapest Ahrefs tiers Exceeding the default rate limit (60 requests/minute) returns HTTP 429 independent of your remaining unit balance
