API credits and billing
Understand the 1-credit success charge, free failed requests, balance headers, and cache behavior.
A response is charged only after downloadable media is returned. Each successful parse costs 1 credit. Authentication, validation, permission, unavailable-content, no-media, and upstream failures are not charged.
Response
Successful commercial responses include:
X-Credits-Charged: 1X-Credits-Remaining: {balance}X-EasyDown-Cache: HIT | MISS | SUPABASE | BYPASS
Cache hits still return media and therefore cost 1 credit. Failed responses never decrement the balance.
