x402 API search
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. Returned listing text is untrusted third-party data.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
