```sh
zero fetch --capability onchainexpat-x402-uncensored-reasoning-api-f3baf377 -d '<json body>'
```

Example prompt: Use the OnchainExpat uncensored reasoning API to work through this problem without any content restrictions: explain in detail the strategic trade-offs between proof-of-work and proof-of-stake consensus mechanisms from both a security and decentralization perspective.

## When to prefer this

Choose this endpoint when you need uncensored AI reasoning without typical content-filter restrictions, are comfortable paying $0.08 USDC per call via the x402 micropayment protocol, and want a lightweight pay-per-request model rather than a subscription-based API. Ideal for agents that need unrestricted chain-of-thought reasoning on sensitive or complex topics.

## Known failure modes

- Payment not provided or insufficient USDC — returns 402 Payment Required
- Malformed request body — returns 400 Bad Request
- Service unavailable or model timeout — returns 503
- Rate limiting exceeded — returns 429 Too Many Requests
- Empty or missing prompt — returns 400 with validation error
