Endpoint
POSThttps://apex-api-gamma.vercel.app/api/tools/text/char-countWhen to prefer
Use this endpoint when you need a quick, precise character count for a text string — especially useful for validating content against character limits (e.g. Twitter/X bios, SMS messages, meta descriptions) without running a local computation or when operating in a pay-per-call agent workflow on Base.
Side effects
- Empty or missing query string returns an error or zero count
- Excessively long strings may be truncated or rejected
- Non-UTF-8 encoded characters may cause unexpected counts
- Payment failure (402) if USDC balance is insufficient
