## 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 upwork-freelancer-fee-calculator-19e6749c -d '<json body>'
```

Example prompt: I just sent my client a $4,500 invoice on Upwork and we've had $600 in prior billings together — can you calculate my take-home pay after Upwork's tiered fees?

## When to prefer this

Use this endpoint when you need to accurately calculate Upwork freelancer take-home pay accounting for the tiered marginal fee structure, especially when the invoice spans a tier boundary (similar to tax bracket math). Prefer this over manual calculation when prior lifetime earnings with the client are non-zero, making simple flat-rate estimates incorrect.

## Known failure modes

- Missing invoiceAmount field returns an error
- Negative or zero invoiceAmount may produce unexpected results
- Stale fee schedule — Upwork may have changed rates since this endpoint was last updated
- Very large invoice amounts may behave unexpectedly if not validated
- Network timeout on the Lambda URL endpoint

## How this service works

Upwork freelancer fee calculator. Applies a documented tiered marginal service-fee schedule (20%/10%/5% at $500/$10,000 cumulative per-client lifetime billing thresholds) to compute take-home pay on an invoice, correctly splitting fees across a tier boundary like a tax bracket. Platform fee policies can change; verify current rates before relying on this for financial decisions.

## Output

Returns the net take-home amount after Upwork's tiered marginal service fees are applied, with fees correctly split across tier boundaries (20% for first $500, 10% for $500–$10,000, 5% above $10,000 of cumulative lifetime billings with that client)
