How this service works
Token buy receipt shortfall — Before and after comparison: Before and after comparison for Token buy receipt shortfall. 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 bounded, deterministic report showing token shortfall (expected minus actual) for both the 'before' and 'after' observations, along with a comparative summary indicating how the shortfall changed between the two snapshots. Not a live scan, safety proof, or trade recommendation — purely a calculation based on the supplied figures.
Example use cases
Trade slippage improvement check
“Before the fee adjustment I expected 1000 tokens and only received 950. After the adjustment I expected 1100 tokens and received 1045. Can you run a before-and-after shortfall comparison to see if the gap improved?”
DEX parameter tuning validation
“I tweaked my DEX swap settings. Before the tweak, expected 5000 tokens, got 4800. After, expected 5000 tokens, got 4950. Can you compare the token receipt shortfall to confirm the tuning helped?”
Automated purchase audit report
“For our weekly token purchase audit: in the first batch we expected 200000 tokens and received 195000, in the second batch we expected 210000 and received 208000. Run the before-and-after shortfall comparison so I can see which batch had worse receipt accuracy.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-buy-receipt-compare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, cost-effective ($0.01 USDC) side-by-side shortfall calculation for exactly two token purchase observations. It is ideal for auditing whether a configuration change, fee adjustment, or swap parameter tweak improved or worsened token receipt accuracy. It is not a live market scanner or trade recommendation engine — use it when you already have two concrete (expected, actual) token pairs and need a structured comparison report.
Side effects
- Missing required fields (expected_tokens or actual_tokens) in either before or after object returns a validation error
- expected_tokens set to zero or below fails due to exclusiveMinimum constraint
- Values exceeding the maximum (1e16) are rejected
- Malformed JSON body returns a 400-level error
- Payment not included or insufficient USDC triggers an x402 payment-required response
