## 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 desk-lead-x402-desk-pack-100-a2c226f0
```

Example prompt: I want to buy the Desk Pack 100 research data pack — it costs $100 USDC and needs to be paid on Base network using the x402 protocol. Can you handle the micropayment and fetch the pack for me?

## When to prefer this

Use this endpoint when you need to access the Desk Lead pack-100 research data tier and can pay $100 USDC on-chain via the x402 v2 protocol on Base (eip155:8453). Prefer over other tiers when the pack-100 data volume/tier is specifically required. Suitable for agents with on-chain USDC payment capability on Base.

## Known failure modes

- Payment rejected if wrong network used (must be Base eip155:8453 for v2)
- Invalid or missing X-PAYMENT-TX header returns 402 Payment Required
- Insufficient USDC balance causes payment failure
- Invalid PAYMENT-SIGNATURE causes authentication error
- BSC network only accepted via legacy acceptsV1 path, not primary v2

## How this service works

Micropay research APIs (x402 v2 + bazaar). Free catalog at /.well-known/x402.json. Primary v2 accepts: Base eip155:8453 only. Legacy X-PAYMENT-TX still supports bsc|base via acceptsV1. Headers: X-PAYMENT-TX, X-PAYMENT-NETWORK, PAYMENT-SIGNATURE. No financial advice.

## Output

A JSON object confirming the transaction with fields: ok (boolean), tier (pack-100), product (desk_pack_100), and priceUsdc (100). Indicates successful payment and data pack delivery.
