크레딧 API — 잔액 확인 & 엔드포인트 비용 | YEB

#What the Credits API does

The Credits API lets you look up endpoint costs and check your balance without making an actual API call. Use it to build cost-aware workflows, display pricing in your UI, or validate you have enough credits before launching a batch job.

#Endpoints

# POST /v1/credits/cost

• Best for: Looking up the credit cost of any endpoint before calling it.
• Single lookup: Send "endpoint": "youtube/channel/audit" to get one cost.
• Bulk lookup: Send "endpoints": ["screenshot/capture", "qr/code"] for up to 50 at once.

# POST /v1/credits/balance

• Best for: Checking your current credit balance from code.
• Returns: Your total available credits.

#Quick start

# Look up a single endpoint cost
curl -X POST "https://api.yeb.to/v1/credits/cost" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: <YOUR_API_KEY>" \
  -d '{"endpoint": "screenshot/capture"}'

# Bulk lookup (up to 50 endpoints)
curl -X POST "https://api.yeb.to/v1/credits/cost" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: <YOUR_API_KEY>" \
  -d '{"endpoints": ["youtube/channel/audit", "qr/code", "geoip/city"]}'

# Check your balance
curl -X POST "https://api.yeb.to/v1/credits/balance" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: <YOUR_API_KEY>"

#Endpoint key format

Endpoint keys follow the pattern module/action. Here are some examples:

#Practical recipes

• Pre-flight check: Call /balance before a batch job. If credits < estimated cost, abort early and notify.
• Pricing page: Fetch all costs with /cost and display them dynamically — always in sync with reality.
• Usage dashboard: Combine /balance with your transaction history to show spend over time.
