## 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-experiments-bundle-subscribe-lab-paidapis-net-5660c89d -d '<json body>'
```

Example prompt: Subscribe my wallet address 0xABC123... to the full x402-experiments bundle on lab.paidapis.net so I get access to all the experimental endpoints.

## When to prefer this

Choose this endpoint when you want to unlock time-limited access to the entire x402-experiments bundle for a specific wallet address with a single $0.03 USDC payment, rather than paying per individual endpoint call. Ideal for developers exploring multiple x402 patterns (oracle, auction, escrow, prediction market) in one session.

## Known failure modes

- Invalid or malformed wallet address returns a validation error
- Payment not received or x402 payment header missing causes 402 Payment Required response
- Expired or insufficient USDC balance causes payment failure
- Network issues with Base mainnet may cause transaction confirmation delays
- Duplicate subscription within active window may not extend access or may return existing expiry

## How this service works

Bundle/all-access pass: one payment unlocks 2 minutes of free access to /api/bundle/market-snapshot, /api/bundle/normalized-gas, and /api/bundle/gas-metrics — instead of paying each separately (?subscriberAddress= required). New mechanic: an access-control check gates every bundled route before it runs.

## Output

Returns a JSON object containing the subscriber's wallet address and an 'unlockedUntil' timestamp indicating when their bundle access expires, confirming the subscription was successfully registered on-chain.
