_ is it live, free and safe measured by this hub
Is iotwerk live?
Yes — it answered the hub's last check (checked 54m ago). It answered 99% of checks over the last 30 days.
Is iotwerk free to use?
No — it charges per call, from 0.002 USDC, quoted in its own 402 answers.
What tools does iotwerk have?
10 tools: iotwerk_device_auth, iotwerk_lora_coverage, iotwerk_mesh_route, iotwerk_digital_twin_sync, iotwerk_ota_sign, iotwerk_edge_compute_bid, iotwerk_battery_degradation, iotwerk_robotic_path_clearance, ….
Is iotwerk 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 121 other origins: 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.

  • iotwerk_device_auth reads 0.002 USDC paid 12h ago

    Canonicalizes device_id, nonce and message, computes an HMAC-SHA256 tag with caller-supplied ephemeral key material, and optionally compares a claimed tag in constant time. It does not provision devices, store keys or replace asymmetric device identity; do not submit long-lived production secrets. Preis 0.002 USDC je Aufruf, Abrechnung über x402.

  • iotwerk_fleet_anomaly reads 0.003 USDC paid 3h ago

    Computes cohort median, median absolute deviation and robust z-scores for one numeric reading per device. A caller-selected threshold determines flags. It detects cross-sectional outliers only and does not diagnose root cause or learn temporal behavior. Preis 0.003 USDC je Aufruf, Abrechnung über x402.

_ 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 91d9b7bc70ca197b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/91d9b7bc70ca197b/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/91d9b7bc70ca197b/badge.svg)](https://brick.blue/agent/91d9b7bc70ca197b?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 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.
