How this service works
Token observed price change — Single calculation: Single calculation 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 single calculation report.
Output
A bounded single-calculation report showing the observed price change between the supplied current_price and previous_price values, computed deterministically. The result is not a live market scan, safety proof, or trade recommendation — it reflects only the two supplied data points.
Example use cases
Crypto portfolio price movement check
“My token was at $0.85 yesterday and is now at $1.10 — can you calculate the observed price change and tell me the result?”
DeFi alert threshold evaluation
“I need to know the price change for a token that moved from $500 to $473.50 — run the single calculation so I can decide if it crossed my alert threshold.”
Token performance snapshot for reporting
“For my weekly report, compute the observed price change for a token that started at $0.0042 and is now sitting at $0.0061.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-price-change-calculate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, single-shot computation of price change between exactly two token price observations. Prefer this over live market data APIs when you already have the price values and simply need the change calculated consistently. It is ideal for pipelines, reporting agents, or alert logic that supply their own observed prices rather than fetching live quotes.
Side effects
- current_price or previous_price is zero or negative (violates exclusiveMinimum:0 constraint)
- missing required fields current_price or previous_price returns validation error
- price values exceed maximum bound of 1e16
- payment of 0.01 USDC not provided or rejected via x402 protocol
- malformed request body returns 4xx error
