## 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 eip-5564-stealth-address-mcp-701e8eeb -d '<json body>'
```

Example prompt: Generate an EIP-5564 stealth address for a private Ethereum payment — here's the recipient's stealth meta-address data: 0xst:0x03abc...def:0x02fed...cba

## When to prefer this

Choose this endpoint when you need EIP-5564-compliant stealth address generation or processing for Ethereum privacy use cases. It is purpose-built for the EIP-5564 standard and suitable when you want to implement one-time addresses for private ETH or token transfers without running your own cryptographic infrastructure.

## Known failure modes

- Invalid or malformed input data string returns an error
- Unsupported key format or curve results in computation failure
- Missing required cryptographic parameters causes processing to fail
- Malformed stealth meta-address input leads to derivation error
- Payment failure (402) if USDC balance is insufficient for the $0.40 per-call fee

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns processed EIP-5564 stealth address artifacts, which may include the derived stealth address, ephemeral public key, view tag, and/or announcement data needed to complete a private Ethereum transaction in compliance with the EIP-5564 stealth address standard.
