How this service works
Token execution fee relative to notional — Adjacent period changes: Adjacent period changes for Token execution fee relative to notional. 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 adjacent period changes report.
Output
A bounded report showing the adjacent period-over-period changes in the ratio of execution fee (fee_usd) to notional value (notional_usd) across the supplied sequence of token trade observations, computed deterministically from the provided data without live market data or trade recommendations.
Example use cases
Tracking fee efficiency across trading sessions
“I have eight consecutive token trades and want to see how my execution fee burden as a percentage of notional is shifting between each adjacent pair — the fees ranged from $1.50 to $3.20 and notional from $800 to $1500. Can you compute the period-over-period changes?”
Detecting fee creep in algorithmic token execution
“My algo has been executing token trades over 12 periods and I'm worried fees are creeping up relative to notional. Here are the fee_usd and notional_usd pairs for each period — can you calculate the adjacent period changes in fee burden ratio to see if there's a trend?”
Comparing fee burden before and after broker change
“I switched token brokers mid-way through my trading log. I have 6 observations total — 3 before and 3 after the switch — with fee and notional values for each. Can you compute the adjacent period changes in execution fee relative to notional so I can see if the new broker is cheaper?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-fee-burden-period-changes?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, bounded calculation of how token execution fee burden (fee as fraction of notional) changes between consecutive observation periods — especially useful for sequential trade logs, algo execution audits, or broker comparison analysis. Prefer this over generic statistics tools when you specifically need adjacent-period delta semantics for fee-to-notional ratios in token trading contexts.
Side effects
- Fewer than 2 rows provided — minimum 2 observations required for any period comparison
- More than 200 rows submitted — array exceeds maxItems limit
- notional_usd value of zero submitted — field has exclusiveMinimum of 0 to prevent division by zero
- fee_usd or notional_usd outside allowed range — values must be between 0 and 1e16
- Malformed row objects with missing required fields fee_usd or notional_usd
- Payment failure or insufficient USDC balance for 0.01 USDC per-call cost
