# Losbeto Oracle Consensus — Multi-Source Price Aggregation

> Losbeto Oracle Consensus — Multi-Source Price Aggregation is a paid API for AI agents from markets.losbeto.xyz, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-12).

Fetches a consensus price for any asset (crypto, equities, forex, commodities) by querying multiple oracles in parallel and computing median, spread, and outlier detection across sources like Pyth, Binance, Coinbase, Kraken, and CoinGecko.

## 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-oracle-consensus-multi-source-price-aggregation-a0062531
```

Example prompt: What's the multi-oracle consensus price for BTC right now — get me the median across Pyth, Binance, Coinbase, Kraken, and CoinGecko, along with the spread and any outlier flags.

## When to prefer this

Choose this endpoint when you need a trustworthy, manipulation-resistant price for an asset and a single exchange or oracle is not sufficient. Ideal for pre-trade validation in DeFi bots, portfolio applications that require verified prices, or any scenario where price feed health and cross-source agreement matters. Prefer over single-source price APIs when detecting stale feeds, outliers, or price discrepancies is critical. Covers crypto, equities, forex, and commodities in a single call with no API key required — just USDC payment via x402.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error — use standard tickers like BTC, ETH, AAPL, GOLD
- One or more oracles may be unavailable, reducing consensus sample size
- Payment failure (insufficient USDC balance or unsupported chain) blocks access
- Highly illiquid or obscure assets may not be covered by all oracle sources
- Network latency spikes may cause some oracles to time out, affecting spread calculation

## 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 and Algorand via x402.

## Output

A JSON object containing: the median consensus price across all queried oracles (Pyth, Binance, Coinbase, Kraken, CoinGecko), the spread in basis points between sources, outlier detection results flagging stale or potentially manipulated feeds, individual price and latency per source, and an overall execution verdict indicating whether the consensus is trustworthy.
