How this service works
Token observed price change — IQR outlier flags: IQR outlier flags 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 iqr outlier flags report.
Output
A bounded IQR outlier flags report for each submitted price-change observation, indicating which rows fall outside the interquartile range. The result is deterministic given the input data and does not reflect live market conditions or constitute a trade recommendation.
Example use cases
Flagging suspicious token pump events
“I have a list of token price snapshots before and after a trading window — current prices are 1.2, 1.35, 8.90, 1.28, 1.31 and previous prices were all around 1.0. Flag which of these price changes look like IQR outliers so I can investigate potential manipulation.”
Pre-trade data quality check
“Before I run my portfolio rebalancing model, I want to clean my price feed — here are 10 current/previous price pairs from my token watchlist. Can you run IQR outlier detection and tell me which observations I should exclude as statistical anomalies?”
Post-event volatility audit
“After yesterday's market event I collected price change data for 20 tokens: can you take my list of current and previous prices and flag which ones are IQR outliers so I know which moves were genuinely extreme versus normal volatility?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-price-change-outliers?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, low-cost IQR-based outlier verdict on a batch of token price-change pairs (up to 200 rows) and do not need a live market scan, predictive model, or trade signal. Ideal for data cleaning, anomaly auditing, and pre-processing pipelines where a statistical threshold flag is sufficient.
Side effects
- Fewer than 2 rows submitted — minimum 2 observations required for IQR calculation
- More than 200 rows submitted — batch size exceeds the maxItems limit
- Zero or negative price values — current_price and previous_price must be strictly positive (exclusiveMinimum: 0)
- Payment failure — 0.01 USDC x402 payment not processed correctly
- Malformed input — missing required fields current_price or previous_price in any row
