# pathcoursehealth.com Chat Completions (MoE)

> pathcoursehealth.com Chat Completions (MoE) is a paid API for AI agents from pathcoursehealth.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Runs an instruction-tuned mixture-of-experts language model via an OpenAI-compatible chat completions endpoint, optimised for high-throughput tasks like classification, extraction, summarisation, routing, and short chat.

## Facts

- Endpoint: POST https://pathcoursehealth.com/v1/chat/completions
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/pathcoursehealth-com-chat-completions-moe-71f2fde3

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 pathcoursehealth-com-chat-completions-moe-71f2fde3 -d '<json body>'
```

Example prompt: Using the fast mixture-of-experts model, classify this customer review as 'positive', 'negative', or 'neutral' and extract the main complaint if there is one: 'The delivery was lightning fast but the packaging was completely crushed.'

## When to prefer this

Choose this endpoint when throughput and cost efficiency are the primary constraints and the task does not require deep multi-step reasoning — e.g. bulk classification, field extraction, short summarisation, or intent routing at scale. The OpenAI-compatible interface makes it a drop-in for existing pipelines, and streaming support suits real-time chat UIs. Prefer a more capable (and more expensive) reasoning model when the task requires complex chain-of-thought, code generation, or nuanced multi-turn dialogue.

## Known failure modes

- Payment not received or x402 payment header missing — 402 Payment Required
- Malformed messages array or missing required fields — 400 Bad Request
- Model overloaded or upstream error — 503 Service Unavailable
- Request times out on very long inputs — 504 Gateway Timeout
- Streaming connection dropped mid-response — partial SSE stream returned

## How this service works

Instruction-tuned mixture-of-experts model for high-volume work: classification, extraction, summarisation, routing and short chat. Chosen when throughput and cost matter more than depth of reasoning. OpenAI-compatible; streaming supported.

## Output

Returns an OpenAI-compatible chat completion object containing the assistant's response text, finish reason, and token usage counts. When stream=true, delivers server-sent event (SSE) chunks progressively as the model generates tokens.

## Response schema (JSON Schema)

```json
{
 "type": "object",
 "description": "OpenAI chat.completion (or SSE stream when stream=true)"
}
