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 x402-gateway-production-up-railway-app-b9cd3b75 -d '<json body>'
```

Example prompt: Use DeepSeek V3.2 to write a Python function that parses a nested JSON object and flattens it into a single-level dictionary — I need clean, well-commented code with edge case handling.

## When to prefer this

Prefer this endpoint when you need DeepSeek V3.2 specifically — offering improved reasoning and coding over V3 — at a low per-call cost of $0.005 USDC. Ideal for agents doing code generation or multi-step reasoning tasks who want a cost-effective alternative to OpenAI models. Use over DeepSeek V3 when improved reasoning quality matters; use over GPT-4o when cost is a primary concern.

## Known failure modes

- Payment failure if x402 USDC balance is insufficient
- Model unavailable or overloaded returning 503
- Malformed request body returns 400 with validation error
- Prompt too long exceeds context window limit
- Network timeout on long-form generation requests

## How this service works

DeepSeek's latest flagship model — improved reasoning and coding over V3 at same low cost

## Output

Returns a text completion from DeepSeek V3.2, which may include natural language responses, reasoning chains, or code snippets depending on the prompt. Billed at $0.005 USDC per call via x402 protocol.
