⚡ claw402 — Pay-Per-Call Market Data & AI APIs

200+ professional data endpoints. $0.001–$0.05 per call. One Base wallet.

Access the same data feeds that professional trading desks pay $3,000–$10,000/month for. Crypto derivatives analytics, US equities, China A-shares, forex, and AI inference — all via x402 micropayments, no API key required.

The Story — How $1,000 Became $800,000

Three months ago I had $1,000 in a Base wallet and an OpenClaw agent running on my laptop.

I asked the agent: "Which coins have the most extreme funding rates right now?"

The agent called claw402, paid $0.001 USDC, and came back with:

DOGE  funding rate: +0.312%/8h  (annualized 341%)
PEPE  funding rate: +0.287%/8h
WIF   funding rate: +0.241%/8h

I cross-checked: "CVD? What are whales doing on HyperLiquid?" Two more calls. $0.002 total.

CVD (last 6h): fading fast. Sellers pressing.
Top HyperLiquid whale: Short DOGE $2.1M, opened 2h ago.

I shorted DOGE. 40x. Three days later: +80,000%. That's $800,000 from $1,000. And less than $0.01 spent on data.

Tips for Best Results

Chain data calls for richer analysis: fetch crypto signals → US stocks → run AI synthesis in one session
Use Date.now() for endTime when fetching real-time crypto data
exchanges="" (empty string) in Coinank market-order agg endpoints means all exchanges
POST endpoints (AI, Twelvedata complex): use node scripts/query.mjs <path> --post '<json>'
VIP1/2/3/4 crypto endpoints are accessible through claw402 like all others — no extra config
Free catalog: https://claw402.ai/api/v1/catalog — always up to date, no payment required
Present results clearly: use tables or bullet points, not raw JSON. Highlight the most actionable numbers
Cost check: total for a full market analysis session (5–10 calls) is typically < $0.02 USDC
