# Losbeto DEX Screener

> Losbeto DEX Screener is a paid API for AI agents from api.losbeto.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

## 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-dex-screener-ea6c2839
```

Example prompt: Pull the latest DEX screener data for a Solana token — I want to see price, liquidity, and trading volume for a specific token pair right now.

## When to prefer this

Choose this endpoint when you need on-chain DEX market data for tokens on Solana or Base networks and are operating in an x402 micropayment-enabled agent environment. Prefer over free alternatives when you need programmatic, pay-per-call access without API key management.

## Known failure modes

- Invalid or missing token identifier returns empty or error response
- Token not listed on supported DEXes returns no data
- Payment not sent results in HTTP 402 response requiring USDC micropayment
- Rate limiting or network errors may cause timeouts
- Malformed query parameters return generic 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 and Algorand via x402.

## Output

Returns JSON with DEX market data such as token price, liquidity pool depth, 24h trading volume, price change percentages, and token pair information sourced from on-chain DEX activity.
