Endpoint
POSThttps://x402-echo-service.onrender.com/web/searchWhen to prefer
Choose this endpoint when an agent needs to retrieve live web search results without requiring an API key or pre-negotiated credentials — ideal for lightweight, pay-per-call search in automated pipelines. It combines keyword and semantic matching, making it suitable for both precise and exploratory queries. Prefer this over scraping individual URLs when you need ranked, multi-source results in a single call.
Side effects
- Empty or whitespace query returns a validation error
- Limit outside 1–20 range is rejected
- Query exceeding 512 characters is rejected
- Payment failure (x402) results in a 402 response with no results
- Upstream search index unavailable causes 5xx error
- Obscure or very niche queries may return low-quality or no results
