Ranks token trade observations by their fee-to-notional ratio (fee burden) across a supplied batch of up to 200 rows, using a deterministic calculation engine.

## 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-relative-to-notional-record-ranking-e468aa4e -d '<json body>'
```

Example prompt: I have 5 token trades — can you rank them by how heavy the fee was relative to the notional? Trade 1: fee $2, notional $1000; Trade 2: fee $3, notional $900; Trade 3: fee $1.50, notional $1200; Trade 4: fee $4, notional $800; Trade 5: fee $2.50, notional $1100.

## When to prefer this

Choose this endpoint when you need a deterministic, ranked comparison of token execution fee burden across a specific batch of supplied trade observations (2–200 rows). It is ideal for post-trade cost auditing, strategy comparison, or fee efficiency analysis where you already have the fee and notional values and want a ranked ordering rather than a live market scan or predictive model.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 rows required
- More than 200 rows submitted — exceeds maxItems limit
- notional_usd is 0 or negative — exclusiveMinimum constraint violated
- fee_usd is negative — minimum 0 constraint violated
- Malformed row objects missing required fee_usd or notional_usd fields
- Non-numeric values supplied for fee or notional fields

## How this service works

Token execution fee relative to notional — Record ranking: Record ranking 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 record ranking report.

## Output

A ranked report of the supplied token trade observations ordered by their fee-to-notional ratio (fee burden), produced via deterministic calculation. Each record is assigned a rank reflecting how high or low its execution fee was relative to its notional value. The result is a bounded report — not a live market scan, safety proof, or trade recommendation.
