## 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 fba-profit-triage-api-7352b4e6 -d '<json body>'
```

Example prompt: Can you triage this FBA lead for me? It's a kitchen product, ASIN B09XYZ1234, titled 'Silicone Baking Mat Set', dimensions 12×8×0.5 inches, weighs 0.6 lb, wholesale cost $4.50, expected sale price $18.99, 35 competitors, prep cost $0.25/unit, inbound shipping $0.40/unit, and roughly 200 monthly sales — tell me the FBA fee, size tier, total fees, and breakeven price.

## When to prefer this

Use this endpoint when you need rapid, per-product FBA profitability triage — especially in automated sourcing pipelines where you need to screen many leads quickly without manually calculating fees. It is ideal for agents doing wholesale or retail arbitrage lead qualification, private label feasibility checks, or any workflow that needs breakeven and fee estimates before committing to a purchase decision. Prefer this over manual fee calculators when you need programmatic, pay-per-call access with USDC micropayments via x402.

## Known failure modes

- Missing required fields (e.g. no dimensions or weight) may result in inability to determine size tier or fees
- Invalid or unrecognized product category may cause incorrect referral fee calculation
- Unrealistic input values (e.g. zero unit_cost or negative dimensions) may produce nonsensical breakeven prices
- Payment failure or insufficient USDC balance on Base will block the call via x402 protocol
- Network or Cloudflare Worker timeout if the endpoint is temporarily unavailable
