api record

DataSnack publishes seven-day forecasts of prediction-market questions. Each forecast is an explicit equation fitted on data, graded daily against standing still, and reworked every night by DataSnack's agents; every record, misses included, is public. Every tool result includes the datasnack.ai page it comes from.

_ is it live, free and safe measured by this hub
Is datasnack live?
Yes — it answered the hub's last check (checked 6h ago). It answered 100% of checks over the last 30 days.
Is datasnack free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does datasnack have?
18 tools: export_options, follow_model, export_model, get_export, search_models, get_reference_workbook, unfollow_model, list_notices, ….
Is datasnack 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.

  • calibration open 6h ago

    How often prediction markets came true at each price, by days before they closed, from the markets DataSnack follows that have resolved.

  • export_model unknown never probed

    Create an Excel workbook of a DataSnack model the signed-in reader covers, with the model's equations as working formulas, its inputs and its record, and return a download link. Waits up to 20 seconds for the workbook; get_export finishes a slower one.

}
    arguments 21 lines
  • get_reference_workbook unknown never probed

    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • list_notices unknown never probed

    The signed-in reader's DataSnack notices from the last 48 hours: changes to followed and covered models.

    mcp-tool

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

    Whether the signed-in reader can cover a market now (so DataSnack builds or keeps working its model every night) and, if not, why; with the reader's allowance and credits.

    mcp-tool

    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • cover_market unknown never probed

    Cover a market for the signed-in reader: DataSnack builds a model for it (or keeps working the one it has) every night, and the reader can export it to Excel. Uses one of the month's coverages from the reader's plan, or a coverage they bought.

    mcp-tool

    {

    }
  },

}
    arguments 17 lines
  • get_model unknown never probed

    Read one DataSnack model: the question, the market's number now, the model's forecast for seven days from now, how the model works, its sources and its graded record including misses.

  "required": [
    "id"
  ],

    arguments 13 lines
  • overnight unknown never probed

    What DataSnack's agents did last night: rounds run, model changes kept and rejected, the biggest miss, where DataSnack and the market differ most, and the scoreboard.

    mcp-tool

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

    How DataSnack's models and agents did over the last 30 days: how far off the seven-day forecasts landed, how often they beat standing still, and how often the direction was right.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 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 a8be6f6ec88b70e4.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/a8be6f6ec88b70e4/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.
