Each campaign defines how creators are paid: CPM (per 1,000 views), flat, per-post, per-view, mixed, and: on the relevant channels: rev-share or spend-share.
Rate tiers let you pay different creator bands differently: for example one rate for creators under 50K followers and a higher one above. Tiers can be banded by views, followers, or Artec Score, and each tier controls its own application mode (invite-only, open to apply, or auto-accept).
You can also override the rate for an individual creator when inviting them.
Guardrails: CPM is capped at $10 per 1,000 views, attribution windows run up to 30 days, and creator slots go from 1 to 30 or uncapped.
A weekly or monthly target spend guides pacing but isn't a hard cap: your actual ceiling is your wallet balance.
