Supported sources include Hacker News, GitHub (repos and repo details), npm, PyPI, Stack Overflow, arXiv, Semantic Scholar, X/Twitter (via xAI Grok), Product Hunt, Dev.to, Hashnode, Lobste.rs, GitLab, Lemmy, Zenn, Qiita, Reddit, YouTube, and the x402 Bazaar directory. Each individual source endpoint costs $0.005 per call, except X/Twitter search at $0.20 due to upstream xAI costs.\n\nBeyond individual searches, Scout offers aggregated report endpoints. The balanced report (`/scout/report`) queries 14 free sources in parallel for $0.005, while the full report (`/scout/report/full`) covers all 18 sources including X/Twitter for $0.25. For AI-synthesized analysis, the `/scout/research` endpoint (POST, $0.25) searches 14 sources and produces structured findings with summary, sentiment, trends, and recommendations. The deep research endpoint (`/scout/research/deep`, POST, $0.50) covers all 18 sources with AI synthesis. All endpoints accept a query string `q` parameter (GET) or JSON body with `query` (POST), plus `per_page` for result count control.\n\nPayment is handled via the x402 protocol using USDC on Base. Alternative access methods include a broker service (API key-based, no wallet needed), an MCP server at mcp.hugen.tokyo, and a Python SDK (`pip install x402-pay`). The API is documented via a full OpenAPI 3.0.3 spec with 18 path definitions covering all endpoints.","tags":[],"capabilities":["multi-source-search","hacker-news-search","github-search","github-repo-details","npm-search","pypi-search","stackoverflow-search","arxiv-search","semantic-scholar-search","x-twitter-search","product-hunt-search","devto-search","hashnode-search","lobsters-search","gitlab-search","aggregated-report","ai-synthesized-research","deep-research","x402-bazaar-search","x402-micropayment"],"categories":["search","aggregation","research"],"synonyms":["multi-source search","meta search API","developer intelligence","tech research API","Hacker News API","GitHub search API","arXiv search","academic paper search","social media search","OSINT API","market intelligence","trend analysis"],"warnings":["No /docs, /pricing, or /README pages are served — all return 404","Response schemas are not defined in the OpenAPI spec (only status code descriptions)","Actual 200 response body structure must be inferred from endpoint descriptions","The x402 challenge sample shows $0.01 for the /scout/x402 endpoint but the OpenAPI spec says $0.005 — minor price discrepancy"],"endpointUrl":"https://scout.hugen.tokyo/scout/x402","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x29322Ea7EcB34aA6164cb2ddeB9CE650902E4f60","amount":"5000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"D6ZhtNQ5nT9ZnTHUbqXZsTx5MH2rPFiBBggX4hY1WePM"},"payTo":"4du4AfkjJEwch2zk3shkPJVZfyJHNDnNjEWC6AboaS5Z","amount":"5000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300}]},"qualityScore":"0.820","qualityRationale":"Full OpenAPI 3.0.3 spec with 18 well-documented endpoints, clear pricing in descriptions, and a live 402 challenge confirming the endpoint is operational.
