whatchuneed Crawl Rate Endpoint

Use this endpoint when you need to retrieve crawl rate information through the whatchuneed pay-per-call gateway and want to pay per use via x402/USDC without managing a subscription. Prefer this over dedicated crawl-rate APIs if you are already integrated with the whatchuneed ecosystem and want a single unified payment and API layer.

• Missing or empty input field returns validation error
• Invalid or malformed input string may return null result or error status
• Network timeout if the upstream rate service is slow
• Payment failure via x402 protocol if USDC balance is insufficient
• Ambiguous input string may return unexpected or empty result data
