x402
String Statistics is a paid API for AI agents from compute-api-production-245d.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-28).
Computes statistical metrics (length, word count, character frequencies, etc.) for a given input string

How this service works
String statistics
Output
Returns computed statistics for the submitted string, including metrics such as total character count, word count, unique character count, character frequency distribution, whitespace count, and other string-level measurements.
Example use cases
Validate input length before processing
“Before I submit this form data to the database, can you compute the string stats for 'Hello World! This is my profile bio.' so I can check if it's within the 50-character limit?”
Word count for content writing
“I need to know the exact word count and character count of this paragraph: 'Artificial intelligence is transforming every industry from healthcare to finance.' Can you run string statistics on it?”
Character frequency analysis for cryptography
“Run string stats on this ciphertext 'XKZQMWVPLRTBN' and tell me the frequency of each character so I can start a frequency analysis.”
Technical details
Endpoint
POSThttps://compute-api-production-245d.up.railway.app/string-stats?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, cheap ($0.001 USDC), deterministic string-level statistics without setting up a local computation environment. It's ideal for agents that need to measure or profile text at runtime — e.g. checking content length, word density, or character composition — without relying on local code execution. Prefer this over NLP-based endpoints when you need raw structural metrics rather than semantic analysis.
Side effects
- Missing 'input' field in request body returns a validation error
- Empty string body may return zero-value statistics or an error
- Extremely large strings may time out or exceed payload limits
- Malformed JSON body returns a 400 Bad Request
- Missing required 'type', 'method', or 'bodyType' fields in the input object causes schema validation failure
- Payment not provided or insufficient USDC balance returns a 402 Payment Required
