usage.credits, the credits the call was charged, and usage.credits_remaining, the workspace’s credits left after it (the x-credits-remaining header has the same number). Calls running at the same time can change the balance, so treat it as a guide, not a reservation.
Unit prices
Facebook costs use the serving source’s actual receipt, including paid failures. Each request may retry a server error once. Matched Facebook accounts reuse their profile lookup and read at most five pages of posts.
Requests that fail aren’t charged by TikHub or Oxylabs. Enrich person collects one profile, then runs two YouTube searches when the profile has a current employer, one otherwise. Each matched video’s transcript takes two Oxylabs requests.
Typical calls
X is the biggest cost driver: each account a search returns is billed, whether or not it matches. Lower
max_results.x when the name is unusual.
Limits
Instagram and TikTok lookups are limited to 10 requests a second, shared across all callers, so busy periods can be slower.
