x402
Token Observed Price Change — Threshold Classification is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-14).
Classifies whether a token's observed price change falls within a caller-specified lower/upper threshold range, returning a deterministic verdict for each supplied token price pair.

How this service works
Token observed price change — Threshold classification: Threshold classification 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 threshold classification report.
Output
Returns a bounded threshold classification report for each supplied token price row, indicating whether the observed price change (derived from current_price and previous_price) falls within the caller-specified lower and upper thresholds. The result is deterministic — no live market data, no predictive scoring, just a verdict per row.
Example use cases
Flagging abnormal token price spikes
“I've got 5 token snapshots with previous and current prices. Can you classify which ones had price changes outside the range of 0% to 20%? Previous prices are 1.0, 2.5, 0.8, 100, 0.05 and current prices are 1.1, 4.0, 0.79, 101, 0.06.”
Portfolio rebalancing trigger check
“For our DeFi portfolio monitoring tool, run a threshold classification on these token price pairs — I want to know which observations fall outside a lower bound of -10 and upper bound of 10, so I can trigger rebalancing alerts.”
Backtesting price change band rule
“I want to test a simple rule: classify each of these 8 historical token price observations as in-band or out-of-band using a lower threshold of 5 and upper threshold of 50. Previous prices: 10, 20, 30, 40, 50, 60, 70, 80. Current prices: 11, 25, 28, 60, 52, 61, 90, 78.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-price-change-threshold?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, per-row verdict on whether a token's observed price change sits inside a caller-defined band. It is not a live price feed, market scanner, or trade signal — it purely classifies supplied historical or snapshot observations. Prefer it when you already have the price pairs in hand and need structured classification output without building custom logic.
Side effects
- Fewer than 2 rows supplied — minItems:2 violation
- current_price or previous_price is zero or negative — exclusiveMinimum:0 enforced
- More than 200 rows submitted — maxItems:200 exceeded
- lower threshold greater than upper threshold — logically invalid band, may yield all-out-of-band results
- Non-numeric values passed for price fields — schema validation error
- Payment not processed or insufficient USDC balance — x402 payment failure
