Simple TWAP (Time-Weighted Average Price)
x402
Simple TWAP (Time-Weighted Average Price) is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Computes a simple (equal-weight) average of an array of price samples as a lightweight TWAP mark for benchmarking trade fills.

How this service works
Simple average of price samples for a light TWAP mark. Call when benchmarking fills against an equal-weight path you already hold. Returns twap and sample count as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a deterministic JSON object containing the computed TWAP value (simple arithmetic mean of the input price array) and the number of samples used in the calculation.
Example use cases
Benchmarking algo execution quality
“I have a list of price samples from my execution window — [102.3, 103.1, 101.8, 102.7, 103.5] — can you compute a simple equal-weight TWAP so I can see how my fills compare?”
Post-trade fill analysis
“I just completed a series of trades at prices [50.1, 50.4, 49.9, 50.2, 50.6, 50.3] — calculate the simple average TWAP mark so I can report benchmark slippage to my desk.”
Lightweight TWAP for DeFi order routing
“Before I route this on-chain order, give me a simple TWAP from these recent price observations: [1823.5, 1825.0, 1822.3, 1824.8] — I need the average and how many samples were used.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/twap-simpleWhen to prefer
Choose this endpoint when you need a fast, deterministic, equal-weight average of price samples with no external dependencies — no RPC calls, no live market feeds, and no API keys required. Ideal for benchmarking trade fills against a simple TWAP mark where you already hold the price path. Prefer this over volume-weighted alternatives (like VWAP) when fill sizes are equal or irrelevant to the benchmark. Use when you need a $0.001 micropayment-gated, advisory-only price computation with full local math transparency.
Side effects
- Empty or missing prices array returns an error or undefined result
- Non-numeric values in the prices array cause computation failure
- Payment failure via x402 protocol blocks the request
- Malformed JSON input body returns a 400-level error
- Very large arrays may cause latency spikes though still deterministic
