api record

UNRENT returns overpaid rent from Solana token accounts. SIMD-0437 lowers lamports_per_byte in five steps; existing accounts keep their old, higher deposit until it is withdrawn.

Flow: scan_wallet (read-only) -> build_reclaim (unsigned transactions) -> the wallet signs -> submit_reclaim. UNRENT never sees a private key.

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_rent_status open 1h ago

    Where Solana's rent reduction (SIMD-0437) stands: the live lamports_per_byte, which of the five steps are live, and when the next is expected. Older accounts keep their higher deposit until it is withdrawn; each step makes more SOL reclaimable.

  • scan_wallet unknown 1h ago

    Reads the token accounts and mints of a Solana wallet and returns the SOL that can be reclaimed now: excess rent (WithdrawExcessLamports, accounts stay open), empty token accounts (CloseAccount) and mint excess, the UNRENT service fee, the net amount, a forecast for the remaining rent steps, and tokens that may optionally be burned and closed (dust). Read-only, needs no signature. Amounts are in SOL. Also returns signUrl: a link to finish the reclaim on unrent.xyz with a browser wallet (Phantom, Solflare, Backpack…), for when you cannot sign for the wallet yourself.

  • build_reclaim unknown never probed

    Re-scans the wallet on the chain and builds the reclaim as unsigned, simulated Solana transactions (base64, versioned). They withdraw excess rent, close empty accounts and pay the service fee as the last instruction; nothing else leaves the wallet. Tokens are only burned for accounts listed in `burn`. The wallet's owner signs every transaction unchanged (the fee payer is the wallet, compute budget instructions may be added) and passes them to submit_reclaim within about 60 seconds, before the blockhash expires. Do not send them yourself.

  • submit_reclaim unknown never probed

    Checks the signed transactions against the ones build_reclaim made (same instructions, same fee, signed by the wallet) and sends them to Solana. Returns the signature and status of every transaction. A claim can be submitted once; after an expired blockhash, build again.

_ 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 fd6ae7fc8734ff53.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/fd6ae7fc8734ff53/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
80%

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.
