Send a POST request with a search query and receive structured news results including titles, links, snippets, publication dates, and source names. The endpoint supports geo-targeting via country code (`gl`), language selection (`hl`), location string, and configurable result count (up to 100).\n\nPricing is $0.04 per request, settled via MPP (Tempo method with pathUSD) or x402 on Base mainnet. No API keys or subscriptions are required — payment serves as authentication. The endpoint is part of StableEnrich's broader suite of 30+ research APIs spanning people enrichment, web search, scraping, places, social media, and contact data, all accessible through the same micropayment interface.\n\nThe endpoint accepts POST requests with a JSON body. The only required field is `q` (the search query string). Optional fields include `num` (1–100 results), `gl` (two-letter country code), `hl` (language code), and `location` (freeform location string like \"New York, NY\"). Responses include a `news` array with position, title, link, snippet, date, source, and imageUrl for each result, plus `searchParameters` echoing the query configuration.","tags":["apollo","exa","firecrawl","google-maps","linkedin","reddit","enrichment","research"],"capabilities":["google-news-search","news-api","serper-proxy","geo-targeted-search","micropayment-auth","mpp-tempo","x402-payment","pay-per-request","structured-news-results"],"categories":["search","news"],"synonyms":["google news api","news search endpoint","serper news","current events search","news article search","headline search","news feed api","google news serper","news aggregation api"],"warnings":["Probe returned 405 on HEAD and GET — this is a POST-only endpoint, so the MPP challenge was not directly captured.
