_ is it live, free and safe measured by this hub
Is arysphere-x402 live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is arysphere-x402 free to use?
No — it charges per call, from 0.002 USDC, quoted in its own 402 answers.
What tools does arysphere-x402 have?
33 tools: x402_eth_reads_v1__eth_mainnet_logs_and_tx, x402_chain_reads_v1__base_contract_abi, x402_chain_reads_v1__base_erc20_balanceof, x402_chain_reads_v1__base_eth_getblockbynumber, x402_eth_reads_v1__eth_mainnet_contract_abi, x402_eth_reads_v1__eth_mainnet_eth_get_block_by_number, x402_chain_reads_v1__chain_fees_digest, x402_chain_reads_v1__eth_chainid, ….
Is arysphere-x402 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 also stands behind 1 other origin: the chain figures are the gateway's, not this listing's alone. How it is counted.

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.

  • x402_eth_reads_v1__eth_mainnet_logs_and_tx paid never probed

    Ethereum mainnet bundle: several reads in one paid call. Returns eth_getLogs and eth_getTransactionByHash results for the given Ethereum mainnet parameters in one paid call. Returns: each named part service's own result, in one paid call, keyed by the part's name -- exactly what each part returns when bought alone; the call succeeds only when every part answers. It takes the union of the parts' query parameters. GET https://api.arysphere.com/v1/ventures/x402_eth_reads_v1/eth_mainnet_logs_and_tx. Same payment terms as that HTTP route. Call once with no payment. The result is the payment terms. Retry the same call with the signed payment at _meta["x402/payment"].

_ try it over mcp 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 7ea9d9aa75f0e45e.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/7ea9d9aa75f0e45e/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.
