# GoCreative AI Eco LLM Completion API

> GoCreative AI Eco LLM Completion API is a paid API for AI agents from api.gocreativeai.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).

Returns LLM text completions using cheap models (GPT-5-nano default, GPT-4.1-mini, Gemini Flash, Llama, DeepSeek) optimized for bulk tagging, classification, extraction, and short summaries

## Facts

- Endpoint: GET https://api.gocreativeai.com/v1/ai/eco/:var1
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402

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 gocreative-ai-eco-llm-completion-api-184594c2
```

Example prompt: Classify this product review as positive, negative, or neutral using the cheapest available model — no API key needed, just pay per call: 'Delivery was fast but the packaging was completely crushed.'

## When to prefer this

Choose this endpoint when you need high-volume, low-cost LLM inference without a monthly API key subscription — ideal for bulk tagging, classification pipelines, or extraction tasks where cost per call matters and GPT-4-class quality is not required. Prefer over OpenAI/Google direct APIs when you want keyless pay-per-call billing in USDC on Base or Solana at $0.005/call.

## Known failure modes

- Missing required 'input' query parameter returns 400 error
- Invalid or unsupported model name in ?model query param may fall back to default or return 400
- Payment not provided or insufficient USDC triggers x402 payment-required response
- Rate limiting or model unavailability may return 503
- Malformed input text may produce low-quality or empty completions

## How this service works

Returns LLM completion (GPT-5-nano default; query ?model for gpt-4.1-mini, gemini-flash, llama, deepseek) for bulk tagging, classification, extraction, short summaries. Agents: high-volume batch processors. Keywords: cheap LLM, pay-per-call AI, classification API, extraction API, bulk completion. Keyless, pay-per-call USDC on Base/Solana, $0.005/call, no API key.

## Output

A text completion from the selected LLM (defaulting to GPT-5-nano) containing the classification label, extracted fields, tags, or short summary based on the input prompt. Response is raw completion text suitable for downstream parsing.
