How this service works
Token observed price change — Before and after comparison: Before and after comparison 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 before and after comparison report.
Output
Returns a bounded comparison report showing the price change (absolute and/or percentage) for both the 'before' and 'after' observation windows, along with a deterministic or caller-threshold verdict on how the two periods compare. Not a live scan or trade recommendation.
Example use cases
Token price impact after listing
“A token was priced at $0.50 before the exchange listing and moved to $0.60, then after listing it went from $0.60 to $0.85 — can you run a before-and-after price change comparison for me?”
Price shift around a protocol upgrade
“Before the protocol upgrade, the token went from $2.00 to $2.10. After the upgrade it jumped from $2.10 to $2.75. Compare those two price change observations and tell me how much bigger the post-upgrade move was.”
Evaluating token pump-and-dump pattern
“I want to compare two price observations for a token: in the first window it moved from $0.10 to $0.15, and in the second window it moved from $0.15 to $0.08. Run a before-and-after comparison so I can see the magnitude of each move.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-price-change-compare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have two discrete token price observation windows (each with a current and previous price) and need a fast, deterministic before-and-after comparison report. Ideal for event-driven analysis — e.g., comparing price movement before vs. after a token listing, news event, or protocol upgrade. Not suitable for live price feeds, real-time scanning, trade signals, or multi-asset batch comparisons.
Side effects
- Missing or zero current_price or previous_price in either snapshot (violates exclusiveMinimum:0 constraint)
- Price values exceeding the maximum allowed value (1e16)
- Malformed JSON body or missing required fields in before/after objects
- Payment failure or insufficient USDC balance for x402 protocol
- Unexpected server error from the shared 50-profile engine
