## 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 gpt-5-6-luna-x402-wallet-payment-activation-agent-7818a6e2
```

Example prompt: Activate my x402 wallet payment for the GPT-5.6 Luna API using my USDC wallet on Base network, with a daily budget of $5 USDC and a max of $0.003 per call, and set the vendor to 'gpt55.558686.xyz'.

## When to prefer this

Choose this endpoint when you need to activate, validate, or configure x402 USDC micropayment wallet settings specifically for the GPT-5.6 Luna API on gpt55.558686.xyz. It is distinct from the chat completion endpoints — use it as a setup or verification step before making paid AI inference calls, especially when deploying an agent that must autonomously manage per-call USDC payments on the Base network with budget controls.

## Known failure modes

- Missing required 'input' object returns validation error
- Invalid or unsupported HTTP method returns 400
- Wallet environment variable not found or misconfigured causes activation failure
- Budget parameters out of allowed range (e.g. max_usdc_per_call > 1000) rejected
- Mismatched expected_network or expected_asset causes payment routing failure
- Payment not settled results in 402 response before activation proceeds
- Service URL or paid_route exceeding maxLength triggers schema rejection

## How this service works

GPT-5.6 Luna API Base USDC and OpenAI-compatible x402 chat: one request for $0.00293, paid by browser wallet or a quote-first agent fallback.

## Output

Returns a JSON object with an 'ok' boolean indicating activation success, a 'tool' field confirming 'x402WalletPaymentActivationAgent', a 'fetchedAt' timestamp, and a 'summary' string describing the result of the wallet payment activation.
