## 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 x402-fair-launch-meme-token-purchase-500-000-tokens-a41b5358 -d '<json body>'
```

Example prompt: Buy me 500,000 X402 fair launch meme tokens for $5 USDC — use my wallet to complete the mint on x402.web5.best.

## When to prefer this

Choose this endpoint when a user wants to purchase exactly 500,000 X402 tokens in a single transaction for $5 USDC. This is the mid-to-large bulk tier for the X402 fair launch — prefer this over smaller tiers (10k, 100k, 300k) when the user wants a significant stake at a favorable per-token rate, but does not need the maximum 1,000,000 token package.

## Known failure modes

- Insufficient USDC balance — payment fails if buyer does not have $5 USDC
- Payment authorization failure — x402 protocol rejects the payment header
- Token supply exhausted — no remaining X402 tokens available for this tier
- Invalid wallet address — token transfer cannot be completed
- Network congestion — blockchain transaction fails to confirm in time
- Rate limiting — too many purchase attempts from same address
