Understanding Quotas

Daily Scan Limit

Your plan determines how many scans you can perform per day:

# Example: Free plan allows 5 scans per day

# After 5 successful scans, further scans return 429 Too Many Requests

curl -X POST https://chainx-api-a154bfdeaf7a.herokuapp.com/api/v1/scan \

-H "X-API-Key: prod-chainx-abc123..." \

-F "file=@contract.sol"

# 6th scan fails with:

# {

# "error": "Daily scan limit exceeded. Limit resets at 2026-02-01T00:00:00Z"

# }

File Size Limit

Files exceeding your plan's limit will be rejected:

# Pro plan: 5 MB limit

# File size: 6 MB → Error

# Response:

# {

# "error": "File size exceeds maximum limit of 5242880 bytes. Upload a smaller file."

# }

Contract Code Limit

The actual smart contract code cannot exceed your plan's character limit:

// Pro plan: 500 KB contract size limit

// This contract is 600 KB → Error when uploaded

Quota Reset

• Daily Limits: Reset at 00:00 UTC each day
• Monthly Quotas: Reset on renewal date
• Unused Scans: Don't roll over to next period
