# Token Execution Fee Burden Threshold Classification

> Token Execution Fee Burden Threshold Classification is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Classifies whether the execution fee relative to notional trade value falls within caller-defined lower and upper thresholds for a batch of token observations.

## 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-threshold-classification-373e50e4 -d '<json body>'
```

Example prompt: I have a list of token trades — for each one I have the fee paid in USD and the notional value in USD. Can you classify whether the fee burden falls between 0.05% and 0.5% (lower=0.0005, upper=0.005) for all of them? Here are four rows: fee $2 on $1000 notional, fee $2.20 on $1100 notional, fee $5 on $800 notional, fee $1 on $2000 notional.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, per-row classification of whether token execution fee burden (fee/notional ratio) is within caller-defined bounds. Prefer it over manual calculation when processing batches of 2–200 trade observations and you want a structured verdict rather than raw ratio values. It is not a live market scanner or safety proof, so do not use it when you need real-time fee data or trade recommendations.

## Known failure modes

- Fewer than 2 rows supplied — minItems violation returns a validation error
- notional_usd of zero will fail due to exclusiveMinimum constraint (division by zero guard)
- Upper threshold lower than lower threshold may produce unexpected classification results
- Rows exceeding 200 items will be rejected due to maxItems limit
- Non-numeric fee_usd or notional_usd values will cause schema validation failure

## How this service works

Token execution fee relative to notional — Threshold classification: Threshold classification 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 threshold classification report.

## Output

A bounded threshold classification report indicating, for each supplied token trade observation (fee_usd, notional_usd pair), whether the fee-to-notional ratio falls within, below, or above the caller-specified lower and upper thresholds. The result is deterministic given the same inputs — not a live market scan or trade recommendation.
