Overview

This skill provides pay-per-call professional market data and AI inference via x402 micropayments on Base. It exposes 200+ endpoints across crypto derivatives, US stocks & options, China A-shares, forex and global time-series, plus GPT/Claude inference and embeddings. No API key, signup, or subscription — a single Base wallet signs and pays calls instantly. Pricing is micro-payments per call (typical $0.001–$0.01 USDC).

How this skill works

Calls are made to HTTP endpoints; each request is paid with a locally signed EIP-3009 USDC transfer from a Base wallet. Query scripts accept GET parameters or POST bodies for AI and complex endpoints, then return a JSON payload with status, url, and data. Chain multiple calls in one agent session to combine market feeds and AI analysis with minimal cost.

When to use it

• Fetch low-latency crypto derivatives metrics (funding, OI, liquidations, whales) for trade signals.
• Retrieve real-time US equities quotes, bars, movers and options chains for monitoring and alerting.
• Access China A-shares fundamentals, northbound flows and margin data for Asia coverage.
• Pull forex, precious metals and global indices time-series or technical indicators for macro analysis.
• Run on-demand AI inference (GPT-4o, Claude, embeddings, images) to summarize or augment market data.

Best practices

• Keep calls focused: fetch only required symbols/intervals to minimize cost and latency.
• Chain checks: confirm signal across funding, CVD/taker flow and whale positions before acting.
• Sign keys locally and never transmit private keys; wallet is the credential — maintain secure storage.
• Cache frequent non-real-time results (e.g., daily fundamentals) to reduce repeated micropayments.
• Use lightweight AI models for quick summaries and reserve larger models for deep analysis due to cost differences.

Example use cases

• Detect crowded longs by querying top funding rates, then confirm with CVD and whale positions before alerting or executing.
• Build a low-cost US equities monitor: snapshots for top movers, plus options chain checks on demand.
• Research China A-share picks using daily OHLCV, fundamentals, and northbound flow aggregation for due diligence.
• Run multi-source macro flash reports: ETF flows, FX rates, gold prices, and a GPT summary in a single agent flow.
• Embed market commentary using on-demand embeddings to index and search trading notes cheaply.
