Pre‑load credits, spend them per research run. The price adjusts to complexity, so simple lookups stay cheap and multi‑vendor deep‑dives stay fair.

How it works?

Each request is scored light, standard, or deep by our planner.

Credits deduct only when the result passes QC and is delivered.

Unused credits never expire.
