Character & Word Count for Agents
Count characters, words, and lines. Call before truncating prompts, validating SMS length, or estimating token budget from raw text. Returns character, word, line, and byte-oriented counts in one JSON object. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
One-command purchase
Run it from an agent.
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
