# HubVibe LLM Raw Completion

> HubVibe LLM Raw Completion is a paid API for AI agents from hubvibe-io.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-22).

Send a prompt (and optional system message) to a configurable LLM provider and model, receiving an unconstrained raw text completion.

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 hubvibe-llm-raw-completion-329b79e5 -d '<json body>'
```

Example prompt: Using the Gemini provider, generate a 3-paragraph explanation of how neural networks learn, with a system message that says 'You are a friendly science teacher' and a temperature of 0.5.

## When to prefer this

Choose this endpoint when you need a completely unconstrained LLM completion — no prescribed output format, schema, or analysis pipeline. It is ideal when you want full control over system message, provider selection (Gemini vs Claude), model variant, temperature, and token budget. Prefer this over llm.analyze when you do not want any opinionated wrapping around the model's response and want the raw model output directly.

## Known failure modes

- Invalid provider name returns an error (only 'gemini' and 'anthropic' are supported)
- Requested model not available if Vertex AI Model Garden access not yet enabled for Anthropic
- max_tokens out of range (must be 1–4096) returns a validation error
- Temperature out of range (must be 0–2) returns a validation error
- Prompt too long for model context window causes truncation or error
- Payment failure via x402 protocol blocks the request
- Provider or model quota/rate-limit reached causing temporary unavailability

## How this service works

LLM text generation / chat completion: a raw completion from your prompt with optional system message, max_tokens and temperature; Gemini by default, other configured models by provider and model. Use it for drafting, rewriting, translation, classification or any prompt, paid per call with no API key or account. Input: prompt. Answer grounded in your own text: llm.analyze.

## Output

A raw text string as generated by the selected LLM provider and model, with no enforced structure or schema — the exact completion the model produces for the given prompt and parameters.
