api record

DepthFeed serves prediction-market order-book depth and history for Polymarket, Kalshi, and Limitless across BTC/ETH/SOL/XRP/DOGE/BNB/HYPE up/down markets. Paid data plans can use polymarket_all_markets for the complete current Polymarket universe in a compact MARKET_NAME | PRICE | DEADLINE format. Then use the *_search_markets tools or the returned market ids to inspect depth and history with *_get_orderbook / *_get_snapshots tools for live and historical depth; `screener` gives a cross-venue top-of-book view. Without an API key you are on the keyless demo tier (BTC + Polymarket, top-of-book…

_ is it live, free and safe measured by this hub
Is depthfeed live?
Yes — it answered the hub's last check (checked 42m ago). It answered 100% of checks over the last 30 days.
Is depthfeed free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does depthfeed have?
15 tools: limitless_get_orderbook, polymarket_get_snapshots, kalshi_get_orderbook, backtest_paths, kalshi_get_candles, kalshi_get_snapshots, polymarket_get_market, bars, ….
Is depthfeed 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.

  • bars reads unknown 42m ago

    OHLCV price bars for US equities and ETFs, Binance spot pairs, and perpetual futures. One minute is the finest resolution; 5Min, 15Min, 1Hour and 1Day are rolled up from it and say so with `derived`. Spell a crypto pair the way the venue does (BTCUSDT, not BTC) and a perpetual with a .P suffix (BTCUSDT.P) — spot and perp are different instruments at different prices. BTCU, ETHU and WLDU are each both a US ETF and a Binance pair, and resolve to the equity — pass venue=binance to reach the pair instead. Optional `venue` selects the market explicitly: us-equities, binance (spot) or binance-futures (perpetuals). Bounded by the same plan history window as every other read (403 HISTORY_LIMIT_EXCEEDED past it); the plan also sets how many symbols one request may carry.

_ 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 7cd07bc034a1e42f.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/7cd07bc034a1e42f/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/7cd07bc034a1e42f/badge.svg)](https://brick.blue/agent/7cd07bc034a1e42f?ref=badge)

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.
