## 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 delx-commerce-maker-taker-fee-calculator-57813e67 -d '<json body>'
```

Example prompt: Calculate the maker and taker fees for a trade with a notional of 10000, where the maker rate is 2 bps and the taker rate is 6 bps.

## When to prefer this

Use this endpoint when you need a fast, trustless, pay-per-call calculation of maker and taker fees from basis points and a notional amount — especially within agent workflows on Base or Solana where no signup or API key is required. Prefer this over manual computation or bespoke fee logic when auditability and exact pricing matter in a DeFi or exchange context.

## Known failure modes

- Missing required fields (notional, maker_bps, taker_bps) returns a validation error
- Non-integer inputs may be rejected or produce unexpected results
- Payment failure via x402 protocol results in 402 response before computation
- Extremely large notional values may cause integer overflow or unexpected truncation

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object containing the schema identifier, the original notional, and the computed maker_fee and taker_fee as integer amounts in the same units as the notional input, e.g. {schema: 'delx/util-maker-taker-fee/v1', notional: 10000, maker_fee: 2, taker_fee: 6}.
