Delx Commerce — Peg Time-Weighted Deviation
x402
Delx Commerce — Peg Time-Weighted Deviation is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Computes the time-weighted absolute deviation of a set of market prices from a target peg value (e.g., 1.0 for stablecoins)

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 with a schema identifier ('delx/util-peg-tw-deviation/v1') and a 'tw_abs_deviation' field containing the computed time-weighted absolute deviation of the provided prices from the target peg as a floating-point number (e.g., 0.005).
Example use cases
Stablecoin depeg risk monitoring
“I have these 10 recent USDC market prices sampled every minute: [0.999, 0.998, 0.997, 0.995, 0.993, 0.991, 0.989, 0.988, 0.987, 0.986]. Can you calculate the time-weighted absolute deviation from the 1.0 peg so I can assess depeg risk?”
DeFi protocol peg health check
“Our algorithmic stablecoin had the following prices over the last hour: [1.002, 1.001, 0.999, 0.998, 1.000, 1.003, 1.001]. Compute the time-weighted deviation from the 1.0 peg — we need this for our on-chain health dashboard.”
Weighted oracle price deviation
“I have oracle price samples for a pegged asset with varying reliability weights — prices are [0.9985, 1.0012, 0.9978, 1.0005] and weights are [0.1, 0.3, 0.4, 0.2]. What's the time-weighted absolute deviation from the 1.0 peg?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/peg-tw-deviation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call computation of time-weighted peg deviation without setting up infrastructure — ideal for DeFi agents, stablecoin monitors, or on-chain risk systems that need verifiable, cheap, single-call analytics on price samples. Prefer it over building custom math when you need reproducible results tied to a defined schema version.
Side effects
- Missing or empty 'prices' array returns an error
- Invalid data types (non-numeric prices or weights) cause a 400-level error
- Mismatched lengths between 'prices' and 'weights' arrays may produce an error or unexpected result
- Payment not included or insufficient USDC (x402) results in a 402 Payment Required response
