search.discoverSylex Search — search 11,000+ products, services, and businesses across every category. Returns ranked results with fit scores. Start here, then use 'details' or 'compare'. If results seem off, use 'feedback' to report it — we're actively improving.
search.detailsGet full details for a specific product by ID. Returns complete data including pricing tiers, features, integrations, review sentiment, and alternatives. Use after 'discover' to deep-dive on a candidate. Data shape varies per product — each product describes itself differently.
search.compareCompare 2-5 products side-by-side. Returns full data for each product so you can analyze pricing, features, and fit differences. Use after 'discover' when you have multiple candidates to evaluate. Each product's data may have a different shape — compare what's relevant to the decision.
search.categoriesBrowse all available product categories with counts and subcategories. Use this to understand what's in the index before searching, or to find the right category/subcategory slugs for filtered searches.
search.alternativesFind alternatives to a specific product. Returns similar products in the same category, scored by relevance (subcategory match, price similarity, ratings). Use after 'details' when exploring options.
search.feedbackReport an issue or suggest an improvement for Sylex Search. We actively use feedback to improve search quality and coverage. Use this when: results are irrelevant, a product is missing, data is wrong, or you have a suggestion. Every report helps.
manage.registerRegister a new product, service, or business in Sylex Search. Returns an owner_token — store it! You need it to update your listing later. Optionally include MCP connection config so other agents can discover and connect to your server.
manage.claimClaim ownership of an existing listing in Sylex Search, or recover access if you lost your owner_token. Two-step process: (1) Call with just product_id to get a verification code and instructions. (2) Place the code at a URL you control, then call again with product_id + verification_url to complete the claim and receive your owner_token. Re-claiming rotates the token (old one dies).
manage.updateUpdate your listing in Sylex Search. Requires the owner_token you received from 'register' or 'claim'. Can update name, description, url, category, pricing, and any custom data fields.
manage.list_mcpAdd or update MCP connection config on your listing so other agents can discover and connect to your MCP server. Requires owner_token. This is how you make your product auto-discoverable by other agents.
