This listing offers one pricing dimension: a Free tier billed by usage units at no cost. There are no paid tiers, instance sizes, or add-ons to compare. You get access to the Arkham Intelligence API, which serves blockchain data such as address and entity balances, counterparty activity, transfers, token intelligence, risk scores, and trade feeds. Usage is tracked in credits across billing periods, and you can review your own consumption per endpoint. Since only the Free dimension applies, pricing does not scale with volume or feature level on the Marketplace.
Top-of-mind questions for buyers
What does one usage unit on the Free dimension represent?
Usage is measured in credits. Each API call consumes credits, and the amount depends on the endpoint you call. You can review call counts and credits consumed per endpoint using the analytics endpoints, and see credit totals per billing period.
Does my cost change as I make more API calls on this dimension?
No cost accrues on the Free dimension regardless of call volume. The API tracks credits consumed across billing periods, including plan credits and any extra usage. On the Marketplace, this dimension carries no charge as call volume grows.
Are there rate limits or request caps I should know about?
Some endpoints apply stricter rate limits. For example, the counterparty endpoints allow one request per second. Batch intelligence requests accept up to 1000 addresses each. Individual endpoints also set default and maximum result limits per request.
