How this service works
Token quote versus received amount — Sequential input-change attribution: Sequential input-change attribution for Token quote versus received amount. 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 (waterfall) report showing how changes in quoted_tokens and received_tokens inputs between the 'before' and 'after' observations contributed to the delta in token shortfall, along with a caller-threshold verdict if applicable. No live market data or trade recommendation is included.
Example use cases
Diagnosing worsening swap slippage
“My first swap quoted 5000 tokens and I received 4850, then my next swap quoted 5200 tokens and I only received 4900 — run the sequential attribution waterfall so I can see which input change drove the bigger shortfall.”
Validating quote accuracy improvement
“Before tuning my DEX parameters I quoted 2000 tokens and received 1940, after tuning I quoted 2000 and received 1985 — can you do the input-change attribution to confirm which factor improved my received amount?”
Monitoring token shortfall drift over time
“Between yesterday and today my token quotes went from 750 quoted / 720 received to 800 quoted / 755 received — give me the sequential waterfall breakdown to attribute what drove the shortfall change.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-quote-shortfall-waterfall?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, reproducible explanation of why a token shortfall changed between two observations — specifically to attribute the change sequentially to input differences (quoted vs received). Prefer this over general slippage calculators when you have a concrete before/after pair of quote and received token amounts and need a structured waterfall decomposition rather than a raw percentage.
Side effects
- quoted_tokens of 0 or below triggers exclusiveMinimum validation error
- received_tokens exceeding 10^16 causes schema validation failure
- missing required fields (quoted_tokens or received_tokens in either before or after) returns a 400 error
- swapped before/after values may produce inverted attribution without error
