Start with independently purchased outcomes, explore more focused utilities from $0.001, or evaluate richer public-data workflows. Samples show the exact response shape; paid calls return fresh results.
Each service below has at least one independently attributed Base settlement. Inspect the static output shape free, then authorize only the call you choose.
