Token Execution Fee Burden Waterfall — Sequential Input-Change Attribution
x402
Token Execution Fee Burden Waterfall — Sequential Input-Change Attribution is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).
Computes a sequential (waterfall) attribution of how changes in fee_usd and notional_usd individually drive the change in a token's execution fee burden (fee relative to notional).

How this service works
Token execution fee relative to notional — Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution report.
Output
A deterministic sequential input-change attribution report showing how each input variable (fee_usd and notional_usd) individually contributed to the overall change in the token execution fee burden (fee/notional ratio) between the before and after states, following a waterfall decomposition methodology.
Example use cases
Trade sizing impact on fee burden
“My token swap had a $2 fee on $1000 notional before, and now the notional grew to $1100 with the same $2 fee — can you run a sequential attribution to show me how much the notional increase drove the change in my fee burden ratio?”
Fee hike contribution analysis
“The execution fee on my token trade jumped from $2 to $2.20 while the notional stayed at $1000 — break down via waterfall how much of the fee burden change came from that fee increase versus any notional movement.”
Comparing two trade scenarios
“I have two trade snapshots: scenario A is $3 fee on $500 notional, scenario B is $4 fee on $800 notional — can you do a sequential input-change attribution to tell me how the fee and notional shifts each contributed to the change in fee burden?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-fee-burden-waterfall?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, ordered decomposition of what drove a change in token execution fee burden between two snapshots — specifically when you want to isolate the marginal contribution of the fee amount versus the notional trade size. Prefer this over generic ratio-change calculators when you need a structured waterfall attribution report rather than just a delta, and when you want a caller-supplied input comparison (not a live market scan or trade recommendation).
Side effects
- notional_usd of zero (excluded by exclusiveMinimum constraint) causes validation error
- missing required fields (fee_usd or notional_usd in either before or after objects) returns schema validation error
- before and after states identical yields zero attribution across all inputs
- extremely large values near the 1e16 maximum may produce floating-point precision artifacts
- malformed JSON body returns 400-level error
