losbeto-mcp

Losbeto x402 market intelligence as native tools in Claude Desktop, Claude Code, or Cursor. Base chain reads with ML on top, ERC-8004 agent reputation, Brazil central-bank macro, multi-oracle price consensus, launch risk, forex, commodities and crypto — plus an OpenAI-compatible LLM gateway. No signup. No API key. Paid tools settle automatically in USDC via x402 — on Base, Solana, Algorand or Polygon.

Registered ERC-8004 agent: agentId 87048 on Base.

    "losbeto": { "url": "https://api.losbeto.xyz/mcp" }
  }
}

The remote server exposes 5 meta-tools that cover the whole 120-endpoint catalog:

  • search_market_data — FREE. Describe what you need in plain language; get matching endpoints with price and parameters
  • get_market_data — fetch any endpoint (delayed sample FREE; live data at the endpoint's x402 price, from $0.001)
  • market_snapshot — one call for a whole area: brazil, global or crypto
  • list_categories — FREE. Every category, endpoint count, cheapest price
  • account_status — FREE. Subscription/credit status for this connection

Without a key, free tools work and every paid tool returns a real but delayed sample at no cost — enough to judge the data before paying. For live data, add a credit key:

{
  "mcpServers": {
    "losbeto": {
      "url": "https://api.losbeto.xyz/mcp",
      "headers": { "Authorization": "Bearer <credit-key>" }
    }
  }
}

Get a credit key with one on-chain payment — Base, Solana, Algorand or Polygon, your choice: POST https://api.losbeto.xyz/buy-credits (plans from $0.99 with bonus balance; machine-readable at GET /plans).

Chain intelligence + agent-native endpoints (all reachable through the meta-tools above):

EndpointPriceWhat you get
/chain-block$0.001Latest Base block: number, age, gas-used %, base fee
/gas-price$0.001Gas now + ML forecast ~10 min ahead (self-fed Holt smoothing) with send/wait recommendation
/chain-balance$0.002ETH + ERC-20 balances, nonce, wallet-class heuristic
/chain-ens$0.002ENS forward and reverse resolution
/chain-tx$0.002Tx status/value/fee/logs, optional LLM explanation (explain=1)
/agent-reputation$0.010On-chain ERC-8004 identity + aggregated reputation for any registered agent
/wallet-verdict$0.020Graded wallet verdict + LLM roast, idempotent, with shareable SVG card
/x402-watch$0.050Watch any third-party x402 endpoint for 30 days — price/availability changes pushed to your webhook

      "env": { "LOSBETO_PRIVATE_KEY": "0x..." }
    }
  }
}

LOSBETO_PRIVATE_KEY = an EVM private key holding a little USDC on Base (optional — free tools work without it). For Solana, Algorand or Polygon payments, use the remote server with a credit key instead.

The npm package exposes the classic 9-tool set:

FREE: try_samples (6 live samples in 1 call) · welcome_free_call (one real-time call, no wallet) · launch_risk_preview · receipts (audit our on-chain sales, honestly labeled)

PAID via x402: launch_risk_brief · br_macro (BCB data) · oracle_consensus · fear_greed · sol_price — the exact current price always comes in the tool's own 402 challenge before you pay (typically $0.01–0.10).

For the full catalog (including the chain reads, ERC-8004 reputation and /x402-watch), use the remote server — the npm package is the classic fixed tool set.
