# Maker/Taker Fee Split

> Maker/Taker Fee Split is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Splits total trading fee drag into maker and taker fee components for a given notional amount and basis point rates, returning deterministic JSON results.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 maker-taker-fee-split-476d0f9f -d '<json body>'
```

Example prompt: Can you split out the maker and taker fee components on a $50,000 notional trade where the maker rate is 8 bps and the taker rate is 20 bps?

## When to prefer this

Use this endpoint when you need a fast, deterministic, local math computation to split fee drag into maker and taker components — especially when comparing venue fee schedules before order routing. Prefer it over manual calculation or more expensive analytics services when you just need exact fee arithmetic without any live market data, API keys, or external dependencies.

## Known failure modes

- Missing required fields (notional, maker_bps, or taker_bps) returns a validation error
- Non-integer or negative values for notional or bps may cause a 400 error
- Payment failure or insufficient USDC balance blocks the request via x402
- Extremely large notional values may hit numeric precision limits

## How this service works

Split fee drag into maker and taker components for a notional. Call when comparing venue fee schedules before routing. Returns maker fee, taker fee, and totals as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

## Output

A deterministic JSON object containing the computed maker fee amount, taker fee amount, and total fee for the specified notional and basis point rates — no live market data or external calls involved.
