# Losbeto Text Summarizer

> Losbeto Text Summarizer is a paid API for AI agents from markets.losbeto.xyz, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-14).

## 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 losbeto-text-summarizer-43a3c343 -d '<json body>'
```

Example prompt: Can you summarize the following earnings call transcript into 3 sentences in English, keeping all the exact numbers? [paste text here]

## When to prefer this

Choose this endpoint when you need to deterministically shrink a specific piece of text — a document, email, article, or filing — before feeding it to a downstream LLM or agent step where context budget is limited. It is purpose-built for factual compression with exact number preservation, not for free-form writing or creative generation (use the /llm endpoint for those). Ideal when you need multilingual output without a separate translation step. Prefer over general LLM calls when cost predictability ($0.008/call, no API key required) and keyless USDC micropayment via x402 matter.

## Known failure modes

- Input text shorter than 40 characters or longer than 6000 characters returns a validation error
- Requesting more than 8 or fewer than 1 sentences returns a parameter error
- Payment not received (HTTP 402) blocks the call from executing
- Invalid or missing 'text' field in body returns a 400 bad request
- Unsupported or misspelled language code may produce unexpected language output or an error

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana, Algorand and Polygon via x402.

## Output

A JSON object containing the summarized text condensed to at most N sentences (1–8), written only from facts stated in the input, with exact numbers preserved, in the requested output language.
