## 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 gig-worker-deduction-optimizer-272ec549 -d '<json body>'
```

Example prompt: I drove 16,000 miles total this year for my Uber and DoorDash work — 8,000 business miles January through June and 6,000 July through December — with $9,000 in actual vehicle costs. My home office is 200 sq ft in a 1,600 sq ft apartment with $24,000 in annual home expenses, I spend $1,200/year on phone and internet at 75% business use, my Schedule C net profit before deductions is $52,000, and I'm filing single with no W2 wages — can you tell me which deduction methods maximize my tax savings for 2026?

## When to prefer this

Use this endpoint when a user is a US-based gig or self-employed worker who needs to compare and optimize Schedule C deductions specifically for vehicle (standard mileage vs actual costs), home office (regular vs simplified method), and phone/internet expenses for tax year 2026. It is purpose-built for the gig economy (rideshare, delivery, freelance) rather than general business tax software. Prefer this over generic tax calculators when the user needs explicit Schedule C line references, IRS-cited rates, and a direct comparison of deduction methods with dollar amounts. Not suitable for W2-only employees, non-US filers, or tax years other than 2026.

## Known failure modes

- Missing required vehicle sub-fields (business_miles_jan_jun, business_miles_jul_dec, total_miles, actual_costs) returns validation error
- Missing required home_office sub-fields (office_sqft, home_sqft, annual_home_expenses) returns validation error
- Missing required phone_internet sub-fields (annual_cost, business_pct) returns validation error
- tax_year value other than 2026 is rejected (enum constraint)
- filing_status value not in ['single','mfj','mfs','hoh'] rejected
- business_pct greater than 1.0 rejected (maximum constraint)
- office_sqft of 0 or home_sqft of 0 may produce zero or limited deductions
- Payment failure via x402/USDC results in 402 response and no computation
- Home office deduction limited to net profit floor (not modelled beyond that — flagged in response)

## How this service works

Pay-per-call finance tools for US gig workers, paid in USDC on Base via x402. Not tax or financial advice.

## Output

Returns a list of deduction items per category (vehicle, home office, phone/internet), each with the recommended method, dollar deduction amount, relevant Schedule C line, an alternative method with its deduction, and explanatory notes. Also includes current IRS mileage rates, total combined deduction, estimated self-employment tax before and after deductions, income tax saved, SE tax saved, total tax savings, and gain versus using suboptimal methods. Flags any limitations or assumptions in the model. Cites IRS sources (e.g. IRS Notice 2026-10).
