Delx Range List
x402
Delx Range List is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Generates a Python-style integer range list (start, stop, step) and returns the values and count without requiring local computation or loops.

How this service works
Generate a Python-style range list. Call when you need index sequences for batching without local loops. Returns values list and count (bounded) 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 a JSON object with a 'values' array containing the computed integers in the range and a 'count' integer representing how many values were produced, bounded to safe limits.
Example use cases
Batch pagination index generation
“Give me a range list starting at 0, stopping at 500, stepping by 50, so I can use those values as offsets when paginating through API results.”
Evenly spaced sampling indices
“I need a list of every 10th index from 0 to 1000 — generate a range starting at 0, stopping at 1000, stepping by 10, so I can sample items at those positions.”
Countdown sequence for workflow steps
“Generate a range from 100 down to 0 stepping by 25 so I can label the progress milestones in my workflow.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/range-listWhen to prefer
Choose this endpoint when an AI agent needs to generate integer index sequences for batching, pagination, or enumeration without executing local Python code or loops. It is ideal in sandboxed or restricted environments where local computation is unavailable, or when you want a declarative, auditable record of the range computation as a bounded JSON result.
Side effects
- Invalid or non-integer input for start, stop, or step returns a validation error
- Step of zero causes a division-by-zero or infinite-range error
- Range that exceeds the bounded maximum count is capped or rejected
- Missing required fields (stop) may return a 400-style error
- Payment not received or insufficient USDC balance results in 402 Payment Required
