The unit of cost
Pricing is straightforward: you pay one credit for every successful retrieval request. Each request retrieves a maximum of 100 records, ensuring efficient data extraction without unnecessary overhead. Even if a query returns an empty result, it still consumes one credit, reflecting the server resource usage for processing the request regardless of the output volume. The rate is $1 per 1000 successful requests, or $0.001 per credit. The minimum paid top-up of $50 adds 50000 credits; it is not required for signup or key issuance. There are no subscriptions and purchased credits do not expire. Public /v1/status is uncharged.
A sample built using 15 successful page requests consumes 15 credits, even if the study's inclusion rules later exclude every record. Additional pages, item lookups and successful repeats each have their own cost. Local reprocessing of a saved response makes no new archive request. Conditional 100 trial credits depend on network-wide anti-abuse eligibility; they are not a guaranteed purchase bonus. Signup displays the key before payment.
