# Omnicall Eco LLM Completion API

> Omnicall Eco LLM Completion API is a paid API for AI agents from omnicall.gocreativeai.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-16).

Returns LLM completions using cheap models (GPT-5-nano default, or gpt-4.1-mini, Gemini Flash, Llama, DeepSeek) for high-volume bulk tagging, classification, extraction, and short summaries via a pay-per-call endpoint.

## Facts

- Endpoint: GET https://omnicall.gocreativeai.com/v1/ai/eco/:var1
- Price: $0.005/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 omnicall-eco-llm-completion-api-c35a632f
```

Example prompt: Using Omnicall's eco model, classify the following product review as positive, negative, or neutral and extract the main complaint if any: 'The battery life is terrible but the screen quality is stunning.' Use the GPT-5-nano model and charge my USDC wallet at $0.005 per call.

## When to prefer this

Choose this endpoint when you need high-volume, low-cost LLM inference for batch classification, tagging, extraction, or short summarization tasks where you want no API key management and are willing to pay $0.005 USDC per call on Base or Solana. Ideal for agents running bulk pipelines over many items where cost per call matters more than response richness. Prefer over OpenAI/Anthropic direct APIs when keyless crypto micropayment billing is required or when you need to switch between multiple cheap models (GPT-5-nano, Gemini Flash, Llama, DeepSeek) without separate credentials.

## Known failure modes

- Payment not fulfilled — 402 response if USDC payment on Base/Solana is missing or insufficient
- Invalid model name in query param — falls back to default or returns error
- Input query string missing — 400 bad request if required 'input' query param is absent
- Model unavailable — specific model (e.g. deepseek) may be temporarily down
- Rate limiting — high-volume bursts may be throttled despite pay-per-call model
- Path param :var1 misconfigured — wrong route results in 404

## How this service works

AI completion, eco tier — the cheapest pay-per-call LLM (GPT-5-nano default; ?model=gpt-4.1-mini|gemini-flash|llama|deepseek). USDC per call, no API key, no signup. A loss-leader for high-volume agent work — bulk classification, extraction, tagging, short summaries — at a fraction of a cent. Step up to /v1/ai/ask for stronger models.

## Output

A raw LLM completion string from the selected cheap model (GPT-5-nano by default, or gpt-4.1-mini, Gemini Flash, Llama, DeepSeek) containing the classification label, extracted entities, tags, or short summary requested in the input prompt. No structured JSON wrapper is guaranteed beyond the completion text itself.
