How this service works
Machine-callable x402-paid utilities for autonomous agents.
Output
Returns a JSON object containing the character count result (e.g. {"result": "93", "operation": "char_count"}), including the numeric count of characters in the input string and the operation identifier confirming which utility was invoked.
Example use cases
Validate input length before submission
“Before I submit this bio to the form, can you count how many characters are in 'I am a software engineer with 10 years of experience in distributed systems' so I know if it fits the 100-character limit?”
Check tweet character count
“Count the characters in this draft tweet for me: 'Excited to announce our new product launch — coming soon to a screen near you! #startup #tech' — I need to make sure it's under 280.”
Measure generated content length
“I just generated a product description — can you count the characters in 'Lightweight titanium frame, scratch-resistant glass, and a 5000mAh battery that lasts all day.' so I can compare it against our max field length?”

Endpoint
POSThttps://creator-desk-x402-isolated.onrender.com/v1/utility/char-count?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent or workflow needs a metered, pay-per-use character counting utility without spinning up its own text-processing logic. It is well-suited for pipelines that already use x402 micropayment infrastructure and need lightweight string measurement as a composable step — for example, validating content length before publishing, enforcing field limits, or logging text sizes at $0.01 USDC per call.
Side effects
- Missing or null 'value' field returns an error or unexpected result
- Non-string value types may cause incorrect counts or errors
- Payment failure via x402 protocol blocks the request entirely
- Service unavailability on Render free-tier hosting causes timeouts or 503 errors
- Malformed options object may cause processing errors
