api record

Verified prices, plan limits, credits, rate limits and overage rules for AI assistants, coding agents, LLM APIs, voice-agent platforms, AI media tools, search/scraping APIs, email platforms and automation SaaS. Every figure was copied from the vendor page on the `checked` date and carries `sourceUrl` and, where available, the vendor `quote`. Prices are USD. `published: false` means the vendor states no number; report the vendor wording instead of inventing one. Start with `search_limits` for a question, `get_tool` for one vendor, `compare_tools` for a side-by-side, `recent_changes` for what…

_ what it can do 6 tools
1 open 5 never probed 1 of 6 classified

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.

  • list_tools open 3h ago

    Vendors/products covered, with ids to pass to get_tool. Optionally filter by dataset id from list_datasets.

    mcp-tool

    {
      "type": "object",
      "properties": {
        "dataset": {
          "type": "string",
          "description": "Dataset id, e.g. \"ai-plans\", \"voice\", \"llm-apis\". Omit for all."
        }
      },
      "additionalProperties": false
    }
    arguments 10 lines
  • list_datasets unknown never probed

    The datasets this server holds (AI plan limits, SaaS usage limits, voice-agent $/min, AI media credits, search and scraping APIs, LLM APIs, email platforms...), with tool counts, last update and page URL.

    mcp-tool

    {
      "type": "object",
      "properties": {},
      "additionalProperties": false
    }
    arguments 5 lines
  • compare_tools unknown never probed

    Compact side-by-side of 2 to 6 products: each plan with price and its headline limits or rates, free tier and overage policy, with check dates. Ids as in list_tools.

    mcp-tool

    {
      "type": "object",
      "required": [
        "tool_ids"
      ],
      "properties": {
        "tool_ids": {
          "type": "array",
          "items": {
            "type": "string"
          },
          "maxItems": 6,
          "minItems": 2
        }
      },
      "additionalProperties": false
    }
    arguments 17 lines
  • recent_changes unknown never probed

    Dated change log for the AI plan limits dataset: price moves, limit changes, new or removed plans, each with the vendor source. Defaults to the last 30 days.

    mcp-tool

    {
      "type": "object",
      "properties": {
        "days": {
          "type": "integer",
          "default": 30,
          "maximum": 730,
          "minimum": 1
        },
        "tool_id": {
          "type": "string",
          "description": "Only this tool."
        },
        "include_wording": {
          "type": "boolean",
          "default": false,
          "description": "Also include re-verification rows that only changed wording or were recorded for the first time."
        }
      },
      "additionalProperties": false
    }
    arguments 21 lines
  • get_tool unknown 3h ago

    Full verified record for a product: plans with prices, limits or rates with vendor quotes, free tier, overage policy, gotchas, source URLs and check date. Pass the tool id (e.g. "claude", "cursor", "vapi", "openai-api"); a name also works.

    mcp-tool

    {
      "type": "object",
      "required": [
        "tool_id"
      ],
      "properties": {
        "dataset": {
          "type": "string",
          "description": "Restrict to one dataset when the same id exists in several."
        },
        "tool_id": {
          "type": "string",
          "description": "Tool id or product name."
        }
      },
      "additionalProperties": false
    }
    arguments 17 lines
  • search_limits unknown 3h ago

    Keyword search across every plan, limit, rate and gotcha. Returns matching rows with value, vendor quote, source URL and check date. Good first call for questions like "Cursor Pro requests per month", "Retell cost per minute", "Gemini API free tier RPM".

    mcp-tool

    {
      "type": "object",
      "required": [
        "query"
      ],
      "properties": {
        "limit": {
          "type": "integer",
          "default": 20,
          "maximum": 50,
          "minimum": 1
        },
        "query": {
          "type": "string",
          "description": "Words to match (vendor, plan, metric). Case-insensitive, all words must appear."
        },
        "dataset": {
          "type": "string",
          "description": "Optional dataset id to narrow the search."
        }
      },
      "additionalProperties": false
    }
    arguments 23 lines
_ 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.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 91e0c5700b209ee0.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/91e0c5700b209ee0/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ 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.
