How this service works
Truncate long text in the middle with an ellipsis. Call when you keep start+end context inside UI/log width limits. Returns truncated text and truncated flag for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns the processed text string with the middle portion replaced by an ellipsis (…) so the total length fits within max_chars, plus a boolean flag indicating whether truncation actually occurred. If the input was already within the limit, the text is returned unchanged with the flag set to false.
Example use cases
Fit long file paths in UI table
“I need to display the file path '/home/user/projects/backend/services/payment/handlers/stripe_webhook_handler.py' in a table column that's only 50 characters wide — can you truncate the middle so both the beginning and the file name at the end are still visible?”
Shorten log lines for terminal output
“This log message is too long for our 80-character terminal display: 'ERROR: Failed to connect to database server at postgres://db-prod-cluster-east-1.internal:5432/maindb'. Truncate it to 80 chars keeping the start and end.”
Display truncated API keys in a dashboard
“Show the API key 'sk-live-aBcDeFgHiJkLmNoPqRsTuVwXyZ1234567890abcdef' in our dashboard label, but truncate the middle to keep it under 30 characters so users can still recognize the prefix and suffix.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/truncate-middleWhen to prefer
Choose this endpoint when you need to preserve both the beginning and end of a string while fitting it into a fixed width — for example, file paths, URLs, identifiers, or log lines where the suffix (like a file extension or error code) is as important as the prefix. Prefer a head-truncation or tail-truncation approach instead when only one end matters. This is a lightweight, stateless local utility requiring no API keys and costing $0.001 USDC per call, ideal for high-frequency formatting tasks inside agent pipelines.
Side effects
- Missing required 'text' field returns a validation error
- Missing or invalid 'max_chars' (non-integer or zero/negative) returns a validation error
- max_chars smaller than the ellipsis itself may produce undefined or edge-case output
- Payment failure via x402 prevents the call from completing
- Very large text inputs may time out or be rejected
