metengine-data-agent_skill

Overview

This skill provides real-time smart-money analytics across Polymarket prediction markets, Hyperliquid perpetuals, and Meteora Solana LP/AMM pools. It exposes 63 endpoints for wallet scoring, insider detection, capital-flow tracking, position analysis, and market intelligence. Payments are handled per-request via the x402 Solana protocol using USDC; no API keys or accounts are required.

How this skill works

Clients perform a two-step paid fetch: an initial GET returns a 402 with payment requirements, the agent signs a payment payload with a Solana signer, then resubmits the request with the PAYMENT-SIGNATURE header. Successful 2xx responses return data plus settlement proof (transaction hash). A separate free pricing endpoint returns the full machine-readable pricing schedule. Agents should persist a local memory file to avoid repeating setup and speed subsequent calls.

When to use it

• When you need on-chain informed signals about smart-money flows and leaderboards across Polymarket, Hyperliquid, and Meteora.
• To score wallets, detect insiders, or compare trader performance before following or copying positions.
• When building dashboards that need low-latency, pay-per-query analytics without managing API keys.
• For automated agents that can sign Solana payments and want provable settlement receipts.
• When you require precise cost estimates from the pricing endpoint before executing high-volume scans.

Best practices

• Always check and read the persistent memory file at ~/.claude/agents/metengine-memory.md before making API calls to reuse bootstrap code and pricing cache.
• Never truncate or trim wallet, contract, condition_id, token_id, pool address, position address, or transaction hash strings—always display full addresses.
• Call the free /api/v1/pricing endpoint to compute expected cost using timeframe, limit, and filters before initiating paid requests.
• Record endpoint results and fallbacks in memory after each call to avoid repeated failures and save tokens.
• Keep Solana signer private keys off-disk in logs and never store private keys in the memory file—only store file paths and public addresses.

Example use cases

• Fetch top trending Polymarket markets for the last 24h and pay per-request to retrieve settlement-proofed data.
• Score candidate wallets for smart-money behavior and compile a watchlist of high-conviction traders.
• Compare Hyperliquid traders across multiple positions to identify professional liquidity providers.
• Analyze Meteora pool fee history and LP performance with paid detailed endpoints for specific pool addresses.
• Automate a bot that signs payments, queries wallet comparisons, and updates a dashboard with provable settlement receipts.
