How this service works
Token execution fee relative to notional — Before and after comparison: Before and after comparison 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 before and after comparison report.
Output
A structured report containing the fee-to-notional ratio for both the before and after scenarios, the absolute and relative change between them, and a deterministic verdict indicating whether fee burden improved, worsened, or stayed the same relative to a caller-defined threshold.
Example use cases
Assessing trade size impact on fee burden
“My token swap fee was $5 on a $2000 notional before, and after increasing my position it was $8 on a $4000 notional — can you compare the fee burden ratio and tell me if the larger trade was more cost-efficient?”
Evaluating broker fee renegotiation outcome
“Before renegotiating my execution fees I was paying $15 on a $500 notional, and after the deal it dropped to $10 on the same $500 — compare those two fee burden ratios and show the improvement.”
Monitoring fee efficiency after market hours switch
“During regular hours my execution fee was $3 on a $1500 notional, but during after-hours it jumped to $6 on a $1400 notional — run a before and after comparison of the fee-to-notional ratio for me.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-fee-burden-compare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, single-call comparison of token execution fee burden (fee as a fraction of notional) across exactly two scenarios. Prefer it over batch endpoints when you have one before/after pair and want a focused change report rather than a table or distribution. It is not a live market scanner or safety checker — use it only for supplied, known values.
Side effects
- notional_usd of zero triggers validation error (excluded by exclusiveMinimum constraint)
- missing required fields (fee_usd or notional_usd) in either before or after object returns schema validation error
- extremely large values may produce precision edge cases
- payment failure results in 402 response with no calculation performed
