Use this endpoint when you need a simple, pay-per-call character count computation without managing API keys. Suitable for agents that need to measure text length on demand as part of a larger workflow, especially when already integrated with the x402 USDC payment protocol on Base.
Side effects
- Empty input string returns zero or error
- Oversized input may be rejected or truncated
- Payment failure (402) if USDC balance insufficient on Base
- Generic API error response if service is unavailable
