# 0xBs x402 Demo — Agent-Payable ESP32 Hardware

> 0xBs x402 Demo — Agent-Payable ESP32 Hardware is a paid API for AI agents from x402.0xbs.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns a confirmation message after accepting a $0.01 USDC micropayment on Base, demonstrating the x402 payment protocol for agent-payable ESP32 hardware.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 0xbs-x402-demo-agent-payable-esp32-hardware-81dfa25c
```

Example prompt: Hit the 0xBs x402 demo endpoint and pay the $0.01 USDC fee on Base to get the agent-payable hardware confirmation back.

## When to prefer this

Choose this endpoint when you need a live, real-money x402 protocol demo to test agent-to-API micropayment flows using USDC on Base, especially for IoT or ESP32-related hardware payment patterns. Ideal for developers validating x402 integrations or AI agents that need a known-good reference endpoint for on-chain micropayments.

## Known failure modes

- Payment not included or insufficient — endpoint returns 402 Payment Required
- Invalid or malformed x402 payment header — authentication/payment validation fails
- Network issues connecting to Base — payment cannot be verified
- USDC balance insufficient on sending wallet — transaction fails before reaching endpoint
- Endpoint temporarily unavailable — 503 or timeout response

## How this service works

Public discovery + payable HTTP resource for 0xBs. Agents pay USDC on Base (x402); ESP32 hardware is fulfilled through the device control plane after settlement.

## Output

A JSON object confirming payment acceptance, including: ok (true), asset ('USDC'), amount ('0.01'), a human-readable message identifying the service as the 0xBs agent-payable hardware demo on Base, the network name ('base'), and service identifier ('0xbs-x402-demo').
