# Losbeto MEV Flow — On-Chain MEV Activity Data

> Losbeto MEV Flow — On-Chain MEV Activity Data is a paid API for AI agents from markets.losbeto.xyz, paid per call via x402, $0.08/call, status unknown (last checked 2026-09-14).

Returns MEV (Maximal Extractable Value) flow data for blockchain trading analysis via a pay-per-call x402 endpoint.

## Facts

- Endpoint: GET https://markets.losbeto.xyz/mev-flow
- Price: $0.08/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/losbeto-mev-flow-on-chain-mev-activity-data-868fc6fc
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_HpebkCO_6_EhxnnB7rAK6

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 losbeto-mev-flow-on-chain-mev-activity-data-868fc6fc
```

Example prompt: Can you pull the current MEV flow data from the Losbeto trading swarm so I can see what arbitrage and front-running activity looks like on-chain right now?

## When to prefer this

Choose this endpoint when you need MEV flow data specifically for Solana or Base chains and want to pay per-call with USDC micropayments via the x402 protocol rather than maintaining a subscription. Best for AI trading agents that need on-demand MEV intelligence without long-term API contracts.

## Known failure modes

- Payment not received — 402 returned if USDC micropayment is not attached
- Invalid or missing properties parameter — may return empty or error JSON
- Endpoint temporarily unavailable — upstream data source outage
- Rate limiting if too many calls in short succession
- Stale data if blockchain RPC connectivity is degraded

## How this service works

Losbeto: 67 endpoints x402 monetizados. Solana + Base. USDC micropayments para AI agents. Preços a partir de $0.003.

## Output

A JSON response containing MEV flow metrics, likely including arbitrage volumes, sandwich attack counts, transaction ordering data, and related on-chain activity statistics for supported chains (Solana, Base).
