# x402.dellbot.win Pro-Tier Chat Completion

> x402.dellbot.win Pro-Tier Chat Completion is a paid API for AI agents from x402.dellbot.win, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

OpenAI-compatible chat completion API offering pro-tier LLMs including Kimi K2.6, Qwen3-Coder 480B, Grok-4, and DeepSeek V4 Flash with tool use and streaming support

## Facts

- Endpoint: POST https://x402.dellbot.win/chat-pro
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 2
- Tags: x402
- Canonical page: https://www.zero.xyz/c/x402-dellbot-win-27afcf99
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_HBgKABJDl1IDmQ0qNDEkN

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-dellbot-win-27afcf99 -d '<json body>'
```

Example prompt: Using the pro-tier Qwen3-Coder 480B model, write me a Python function that parses nested JSON and flattens it into a single-level dictionary, with streaming enabled so I see output as it arrives.

## When to prefer this

Choose this endpoint when you need access to the most capable models available on the x402 Bazaar, including Grok-4 family, Qwen3-Coder 480B, or Kimi K2.6 for demanding reasoning, advanced code generation, or complex multi-step tool use. Prefer this over the cheaper/mid-tier sibling endpoints when task complexity justifies the higher capability tier. Ideal when streaming SSE responses or structured tool/function calling is required with a top-tier model.

## Known failure modes

- Invalid or unsupported model name returns 400 or falls back to default
- Malformed messages array causes 422 validation error
- Payment not included or insufficient USDC causes 402 Payment Required
- Tool schema invalid format causes tool_calls to fail or be ignored
- Stream connection dropped mid-response if network is unstable
- Rate limiting or overload returns 503 or 429

## How this service works

Pro-tier reasoning & code. Claude Sonnet 5, Kimi K2.7 Code, Qwen3.7 Plus, Qwen3-Coder 480B, Grok-4 family (4-20, 4-3), DeepSeek V4, OpenAI gpt-54/gpt-52/gpt-53-codex, GLM 5.1. OpenAI-compatible. Supports tools/tool_choice and stream:true SSE.

## Output

An OpenAI-compatible chat completion response containing the assistant's generated message, optionally streamed as SSE events. If tools were provided, may return tool_call objects with function names and arguments. Includes token usage metadata.
