api record

Look up prices, models, web pages and market data. get_price, list_price_symbols and list_models are free and work without a key. Paid tools need a SingIt API key and are charged per call to that key's SingIt limits, in USDC on Base or Solana. web_search and read_page need the key's "search" scope; the market data tools need its "tools" scope and a Base account for now. Keys made before paid data tools existed need a new key for those.

_ is it live, free and safe measured by this hub
Is singit live?
Yes — it answered the hub's last check (checked 3h ago). It answered 100% of checks over the last 30 days.
Is singit free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does singit have?
5 tools: Key spending limits, Free model answers, Paid model answers over x402, Web search and page reading, Price lookups.
Is singit 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.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 22 doors on this origin, so the chain figures are the operator's.

_ what it can do 5 tools
5 never probed 0 of 5 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.

  • key-spending-limits unknown never probed

    get_limits and get_receipts read key limits and spend. Caps apply only to calls with that key to SingIt MCP and its /v1 endpoint; they do not limit spending elsewhere or protect an agent’s own wallet.

    limitsreceipts

  • free-model-answers unknown never probed

    Limited free model answers without a wallet or key.

    llmfree

  • paid-model-answers-x402 unknown never probed

    Pay per call in USDC on Base or Solana through the x402 API. Use singit/auto to pick a model by tier.

    llmx402

  • web-search-and-page-reading unknown never probed

    Paid calls with a SingIt key and search scope on Base or Solana.

    searchmcp

  • price-lookups unknown never probed

    Free crypto, metal and FX price lookups without a key.

_ try it over a2a 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 caa6612cd95b45c3.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/caa6612cd95b45c3/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 knowoff the mcp door
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.
