## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability token-execution-fee-burden-batch-calculator-480006b1 -d '<json body>'
```

Example prompt: Can you batch-calculate the execution fee burden relative to notional for these trades: trade 1 has a $2 fee on $1000 notional, trade 2 has a $2.20 fee on $1100 notional, and trade 3 has a $5 fee on $800 notional?

## When to prefer this

Choose this endpoint when you need to compute fee-to-notional ratios for multiple token trades in a single deterministic call without needing live market data, real-time pricing, or trade recommendations. It is ideal for post-trade analysis, fee efficiency audits, and cost comparisons across batches of up to 200 observations. Prefer it over single-row variants when processing multiple trades at once to minimize round trips and cost.

## Known failure modes

- Empty or missing rows array returns a validation error
- notional_usd of zero is rejected due to exclusiveMinimum constraint (division by zero)
- Row count exceeding 200 items triggers a maxItems validation failure
- Negative fee_usd or notional_usd values rejected by minimum:0 constraints
- Malformed JSON body returns a 400 parse error
- Payment not included or insufficient USDC results in 402 Payment Required

## How this service works

Token execution fee relative to notional — Batch calculation: Batch calculation 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 batch calculation report.

## Output

Returns a batch calculation report containing, for each input row, the computed ratio of fee_usd to notional_usd (fee burden as a fraction or percentage of notional). Results are deterministic given the supplied inputs; no live market data or trade recommendations are included. Up to 200 row results per call.
