Delx Commerce Weight Normalize
x402
Delx Commerce Weight Normalize is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).
Normalizes an array of non-negative weights so that they sum to 1, returning normalized values along with count and sum metadata.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the normalized weight array (each value divided by the total sum), the original sum of all weights, the count of input weights, and a validity flag indicating whether normalization was possible (i.e., sum is non-zero).
Example use cases
Normalizing portfolio allocation weights
“I have raw portfolio weights of [30, 50, 20] for my three assets — can you normalize them so they sum to 1 and give me each asset's share?”
Scaling feature importance scores
“I've got feature importance scores from my model — [0.8, 1.6, 0.4, 0.2] — can you normalize them into a proper probability distribution that sums to 1?”
Converting vote tallies to proportions
“We got votes of [120, 240, 40] across three candidates — normalize these to fractional proportions and confirm the total is valid.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/weight-normalize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-use normalization of a numeric weight vector without setting up your own math library or server-side computation. Ideal for agents that need on-the-fly probability distribution computation, especially in contexts where verifiable, micropayment-gated utility functions are preferred over self-hosted solutions.
Side effects
- All weights are zero — sum is 0, cannot normalize, valid flag returns false
- Non-numeric values in the weights array cause a validation error
- Empty weights array returns count 0 with no normalized output
- Negative weights may be rejected or flagged as invalid
