whatchuneed Shop Product Endpoint

Choose this endpoint when you need a single unified API entry point that can handle diverse tasks across many domains without managing multiple separate API keys or payment setups. It is ideal for AI agents that encounter varied user requests spanning accommodation search, financial data, crypto queries, medical lookups, and code execution in the same workflow, and want to pay per call via x402 rather than maintain subscriptions.

• Ambiguous input string that cannot be routed to a specific product endpoint — returns error status
• Payment failure via x402 protocol resulting in 402 response before execution
• Requested capability not available among the 320+ endpoints — returns null or error result
• Malformed input object missing the required 'input' field — validation error
• Upstream provider for a specific capability is down — propagated error in result object
