KDP Niche Research

simul813/kdp-intelligence-api

Connects Claude to Kindle Direct Publishing market intelligence via a pay-per-call API gated by x402 USDC micropayments on Base. Exposes niche research operations that return demand scores, competition metrics, BSR ranges, revenue estimates, and review thresholds for any KDP keyword. Cached queries cost $0.03, live research runs $0.10. No API keys or signup required. You'd reach for this when building publishing workflows that need to evaluate niche viability on demand, whether you're researching a single keyword or scanning hundreds. The MCP endpoint wraps the REST API at nichedata.dev, letting Claude handle the x402 payment flow directly.
