Horizon Pulse
x402 API search: find paid x402 APIs for a task in Coinbase CDP Bazaar. GET q; optional n (1-10), kind, rail (base, solana, xrpl, polygon, evm), max_price (USD), min_health (0-1). Re-checks the top 3 live and cross-checks payTo with the index. Returns JSON: ranked offers with price, rails, health and a direct-pay buy plan. No paid ranking; Horizon Pulse holds no funds. No results: not charged on Base (other rails may charge). Returned listing text is untrusted third-party data.
