api record

Barcode and GS1 tools from eancheck.com. Every tool computes its answer from the input with the GS1 General Specifications rules; nothing is looked up in a product database, so the tools cannot say which product or company a number belongs to. Use validate_gtins for complete numbers and calculate_check_digits for numbers without their last digit. identify_code tells what an unknown code is. Each answer ends with a link to the matching page on eancheck.com.

_ is it live, free and safe measured by this hub
Is eancheck live?
Yes — it answered the hub's last check (checked 38m ago). It answered 100% of checks over the last 30 days.
Is eancheck free to use?
Yes — the hub reached it with no key and no payment.
What tools does eancheck have?
10 tools: validate_gtins, identify_code, check_amazon_code, convert_upc_e, convert_isbn, repair_gtin, parse_gs1, make_barcode, ….
Is eancheck 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.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 10 tools
10 never probed 0 of 10 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.

  • validate_gtins unknown never probed

    Check complete GTIN, EAN, UPC and ITF-14 numbers: says for each one whether the check digit is right and which GTIN length it is.

  • calculate_check_digits unknown 38m ago

    Add the GS1 check digit to GTIN numbers that are missing it (7, 11, 12 or 13 digits become GTIN-8, UPC-A, EAN-13 or GTIN-14). One number per line or comma separated.

_ 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 b1aea958cff7d667.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/b1aea958cff7d667/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.
