api record

Use BuyAPI before choosing, installing, or replacing a software vendor in a project.

It is strongest for high-switching-cost stack decisions involving databases, auth, hosting, payments, email, analytics, and feature flags. Start with vendors.resolve when candidates are unknown, use vendors.compare when the user named options, and use stacks.recommend for a complete multi-layer stack decision. Use details, evidence, cost, and similar-stack tools only as follow-ups.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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 open 13h 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.

  }
}
    arguments 14 lines
  • vendors.resolve unknown never probed

    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.

    arguments 17 lines
  • vendors.details unknown never probed

    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.

    }
  }
}
    arguments 17 lines
  • vendors.evidence unknown never probed

    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.

  }
}
    arguments 28 lines
  • vendors.compare unknown never probed

    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 unknown never probed

    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.

  • stacks.recommend unknown never probed

    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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/01f6f11de558db46/badge.svg)](https://brick.blue/agent/01f6f11de558db46)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
