How this service works
Token observed price change — Weighted result mean: Weighted result mean for Token observed price change. Supplied token observations only. Deterministic calculation or caller-threshold verdict, not a live scan, safety proof or trade recommendation. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded weighted result mean report.
Output
Returns a bounded weighted result mean report summarizing the aggregated price change across all supplied token observations, incorporating the specified weights. The output is a deterministic calculation — not a live market scan or trade recommendation.
Example use cases
Portfolio token performance summary
“I have 5 token trades this week — starting prices were 0.50, 1.00, 2.50, 0.80, and 3.00, ending at 0.55, 1.15, 2.40, 0.95, and 3.30. Weight them by trade volume: 10, 50, 5, 20, 15. What's the weighted mean price change across all of them?”
Index rebalancing price drift check
“I need to summarize price changes for 3 index constituents: token A went from 100 to 108, token B from 50 to 47, token C from 200 to 214. Weight them by market cap: 3, 1, 2. Give me the weighted mean observed price change.”
Backtesting strategy performance aggregation
“For a backtest I ran over 6 periods, the token started at these prices: 1, 1.05, 1.1, 0.98, 1.02, 1.08 and ended at 1.05, 1.1, 1.08, 1.05, 1.08, 1.15. Weight each period equally at 1. Can you compute the weighted mean price change across all those observations?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-price-change-weighted-mean?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a fixed batch of token price observations (current and previous prices) and need a single weighted-average price change metric. Ideal for portfolio aggregation, index summarization, or backtesting rollups where you supply your own data and want a deterministic, reproducible result rather than a live market feed or raw price lookup.
Side effects
- Fewer than 2 rows supplied — minimum 2 observations required
- More than 200 rows or weights provided — maxItems limit exceeded
- current_price or previous_price is zero or negative — exclusiveMinimum constraint violated
- Weights array length does not match rows array length
- Non-numeric values in prices or weights fields
- Payment failure — 0.01 USDC x402 charge not processed
