# NetIntel OpenAI GPT-5.4 Chat Completion Proxy

> NetIntel OpenAI GPT-5.4 Chat Completion Proxy is a paid API for AI agents from netintel.dev, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-13).

Proxy endpoint that forwards chat completion requests to OpenAI's GPT-5.4 model and returns responses in the standard OpenAI chat.completion format, billed per call via x402 micropayments.

## Facts

- Endpoint: POST https://netintel.dev/openai/gpt-5-4
- Price: $0.25/call
- Payment: x402
- Status: unknown

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 netintel-openai-gpt-5-4-chat-completion-proxy-3ad0f482 -d '<json body>'
```

Example prompt: Use the NetIntel GPT-5.4 endpoint to generate a response: 'What are the top 3 benefits of using micropayments for API access?' — pay per call in USDC, no API key needed.

## When to prefer this

Choose this endpoint when you need GPT-5.4 chat completions without an OpenAI API account or subscription, want pay-per-call USDC billing on Base or Solana via x402, and need the guarantee that failed or errored calls are never charged. Useful for agents that need occasional LLM inference without committing to a monthly API plan.

## Known failure modes

- Upstream OpenAI failure — not billed, server error returned
- Invalid message format or missing required chat fields — input validation rejection, not billed
- Insufficient x402 payment or payment verification failure — call rejected before processing
- Rate limiting or quota exhaustion at the OpenAI layer — error returned
- Malformed JSON body — validation error, not billed

## How this service works

Call OpenAI's gpt-5.4 via a single pay-per-call x402 endpoint — no OpenAI account or API key needed, pay $0.25 per request in USDC. Standard OpenAI chat.completions request/response shape, capped input and output. Search terms: OpenAI, gpt-5.4, chat completion, LLM, no API key.

## Output

Returns a standard OpenAI chat.completion JSON object including the assistant's reply message, model name (gpt-5.4), finish_reason, and token usage breakdown (prompt, completion, total tokens), structured identically to the OpenAI API response format.
