## Services

- [badhttp /402/pay/base — x402 Payment Test Endpoint](https://www.zero.xyz/c/badhttp-402-pay-base-x402-payment-test-endpoint-021c57d1/llms.txt): $0.01/call via x402. Accepts a real $0.01 USDC x402 micropayment on Base and returns a confirmation object with transaction details, demonstrating a live x402 paywall flow.
- [badhttp Chat Completions — Intentionally Misbehaving LLM Endpoint](https://www.zero.xyz/c/badhttp-chat-completions-intentionally-misbehaving-llm-endpoint-146f0df2/llms.txt): $0.002/call via x402. Provides a chat completions endpoint that deliberately misbehaves (slow responses, broken JSON, flaky behavior, x402 paywalls) to test how clients, SDKs, and agents handle HTTP edge cases.

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