// HOW BILLING WORKS
BATCH ENDPOINTS
= ONE REQUEST.
Bulk endpoints don't multiply. /v1/prices/batch with 50 items is one request, not fifty.
The limit param caps how many items come back per batch call — 100 on FREE, 1,000 on every paid tier.
Example · PRO plan · month-to-date
Watchlist refresh · 250 items × 6 markets · /prices/batch1 req
Buy-order pull · 50 items · /bids/batch1 req
Sales lookup · AWP Asiimov · /v1/sales1 req
Price history · 365d · /prices/history1 req

FREQUENTLY ASKED.
Any HTTP call to api.cs2c.app/v1/* counts as one request. Batch endpoints (e.g. /v1/prices/batch) count once per call regardless of how many items you return.
