## 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 hivemindos-veil-cash-private-usdc-send-reservation-e53c8a87 -d '<json body>'
```

Example prompt: I want to send 50 USDC privately on Base using Veil Cash — can you reserve a proving key so I can generate the proof locally and keep the recipient completely off HivemindOS's servers?

## When to prefer this

Choose this endpoint when an agent or user needs to send USDC on Base with on-chain privacy guarantees, keeping recipient and transaction details entirely local. Prefer over standard transfers when regulatory sensitivity, counterparty privacy, or financial confidentiality is required and the caller can run the @veil-cash/sdk locally.

## Known failure modes

- Payment below minimum $0.25 fee rejected
- Reservation expires before local proof generation completes
- Invalid or unsupported send amount
- Base network congestion causing reservation timeout
- x402 payment verification failure

## How this service works

Prepare a Veil Cash private USDC send on Base. The x402 price is HivemindOS's disclosed 1% service fee for the requested send amount, with a $0.25 minimum and $10 maximum. Returns time-limited proving-key access for local @veil-cash/sdk execution. The recipient, Veil key, proof, and final transaction never go to HivemindOS.

## Output

Returns a time-limited proving-key access token that the caller uses locally with the @veil-cash/sdk to generate a zero-knowledge proof and execute the private USDC transaction on Base. The recipient address, Veil key, proof, and final transaction are never sent to HivemindOS.
