_ is it live, free and safe measured by this hub
Is Loyal Spark live?
Yes — it answered the hub's last check. It answered 100% of checks over the last 30 days.
Is Loyal Spark 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 Loyal Spark have?
42 tools: get_platform_info, get_my_profile, generate_program_defaults, get_program_workflow_status, list_loyalty_programs, create_loyalty_program, register_loyalty_program, activate_loyalty_program, ….
Is Loyal Spark 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.

    Get factory calldata to deploy a new loyalty token on Base. Defaults to B20 (Base-native B20 asset standard, ERC-20 compatible, single tx, active immediately). Pass token_standard='erc20' for the legacy factory. For B20, MINT_ROLE is granted atomically to the merchant admin AND to the agent's CDP wallet (or explicit extra_minters) so autonomous agents can mint with no follow-up transaction.

  • mint_loyalty_tokens unknown never probed

    Record mint intent and get a fee-first `calls[]` bundle: protocol fee mint FIRST, then the recipient mint. The protocol fee is charged in the merchant's own loyalty tokens (not USDC). Submit both calls in order (atomically via EIP-5792 send_calls if your wallet supports it), then call confirm_mint_fee (or POST /agent-api/mint/confirm) with obligation_id, fee_tx_hash, and recipient_tx_hash. Unconfirmed fee obligations block future mints. Accepts a 0x Base wallet address or customer email in recipient_address (or recipient_email), automatically resolving the customer's wallet.

  • confirm_mint_fee unknown never probed

    Confirm a prepared mint on Base. Verifies the protocol-fee mint and, when recipient_tx_hash is set (or the fee receipt already contains the recipient mint), writes customer_tier_status so get_token_balance leaves 0.

_ 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 agent card — 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 f1ae777959b63b4a.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/f1ae777959b63b4a/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 a2a door
card completeness
90%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
