Is buyapi live?

Yes — it answered the hub's last check (checked 3h ago). It answered 98% of checks over the last 30 days.

Is buyapi free to use?

Yes — the hub reached it with no key and no payment.

What tools does buyapi have?

7 tools: vendors.compare, vendors.estimateCost, vendors.evidence, vendors.resolve, stacks.recommend, vendors.details, stacks.findSimilar.

Is buyapi safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• stacks.findSimilar reads open 3h ago

  Finds reviewed public stack examples related to a vendor, or recent curated stack examples. Use this when the user asks who uses a tool, what similar builders use, or wants examples of real stack combinations. Do not use it as a generic recommendation tool.

• vendors.compare reads unknown 28h ago

  Compares two or more already-known BuyAPI vendors for a specific workload or decision. Use this when the candidate set is known, for head-to-head questions like "Convex vs Supabase vs Neon for a realtime SaaS" or "Stripe vs Paddle for a marketplace". If the user has not named candidates, use vendors.resolve first.

• vendors.estimateCost reads unknown 11h ago

  Produces directional monthly cost estimates from BuyAPI pricing data and explicit workload inputs. Use this only when the user asks for cost math and provides explicit workload inputs. Missing workload fields are returned as assumptions or unknowns instead of being hallucinated. Treat results as BuyAPI claim-based estimate math; verify exact billing in first-party docs, vendor CLIs, or vendor MCPs before purchase or production decisions.

• vendors.evidence reads unknown 3h ago

  Returns recent reviewed BuyAPI evidence rows for a vendor, category, stack, or comparison. Use this when the user asks why BuyAPI believes something, what sources support a recommendation, or what recent human/source/opinion/history signals exist. This is a trust and provenance follow-up, not the first recommendation tool.

• vendors.resolve reads unknown 28h ago

  First stop for category-specific vendor recommendations and vendor ID discovery. Finds BuyAPI vendor IDs for a user question; provide category when known. Use this when the user asks which provider in a category fits their constraints. With a covered category, the response includes ranked results plus a top-3 decision matrix with fit labels, confidence, tradeoffs, cost notes, freshness, and sources. Do not use this for local coding/debugging/docs questions unless they involve choosing a software vendor or tool. If the category is outside BuyAPI's corpus, the tool returns an explicit "not in corpus yet" result instead of inventing vendors.

• stacks.recommend reads unknown 3h ago

  Recommends a complete stack from BuyAPI's corpus with a structured decision matrix, cost estimate, assumptions, unknowns, alternatives, and sources. Use this when the user is starting a project or asks for a complete multi-layer stack choice. Do not use this for local coding/debugging/docs questions that do not involve software or vendor selection. Do not call vendors.resolve first; this tool handles retrieval and ranking.

  Follow-up tool for one known vendor. Retrieves detailed pricing, features, limits, gotchas, comparisons, and source provenance. Call vendors.resolve first unless the user already provided a BuyAPI vendor ID like /database/supabase. Use this after a candidate is selected and the user needs claim-level pricing, limit, gotcha, or provenance details.
