api record

GBLIN hosted MCP (stateless, no auth, 60 req/min/IP, everything here is free). THREE THINGS LIVE HERE. (1) AI ACTION RECEIPTS - a public append-only RFC 6962 transparency log for AI actions. receipts.seal appends the SHA-256 of your input (and optionally your output) plus a short public label, and returns a portable receipt: Ed25519 signature, inclusion proof, C2SP checkpoint, tree root anchored daily on Base. Minimal call: receipts.seal {action: "what you did", input_hash: "<sha256 hex>"} - demo mode, 5/day/IP, receipts marked demo:true. Then receipts.verify checks it with pure math, no…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

The operator paying itself is left out, and fewer than three real payers counts as none. This address also stands behind 1 other origin: the figure is the gateway's, not this listing's alone.

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.

  • auction.state open 1h ago

    Read the GBLIN rebalancing auction on Base. The vault does not rebalance itself and pays nobody to do it: when a basket row drifts past its band it holds a Dutch auction, and whoever trades with it toward the target weights is the counterparty, at the oracle price adjusted by a premium that starts at a discount and rises to a cap over one ramp. Returns, per row, the side the vault takes, the gap in ETH, the token and amount the bidder hands over, and unsigned calldata (approval + bid). The premium is the whole reward; nothing is paid out of the vault.

    Verify GBLIN protocol governance state: confirms whether the GBLIN vault is owned by the 48h Timelock, reads the timelock's min delay and grace period, reports role member counts, and surfaces any pending asset-addition proposal on the index contract. If an operation_id is provided, also reports the status of that specific timelock operation. Read-only — use this to gate trust-sensitive agent actions.

  • payments.relay unknown never probed

    Have GBLIN's relay carry a signed GBLIN payment on chain for a payer that holds no ETH. Pass the payment and the relay fee, each as { authorization, signature }, both prepared by prepare_gblin_payment with relay: true and signed by the payer's wallet. The relay checks both against the chain, simulates them and submits them in one transaction through Multicall3: either both settle or neither does. The fee is paid in GBLIN at the live NAV. Returns the transaction hash and its outcome. This moves funds: run it only with authorizations the payer meant to sign.

Every output bound is non-zero and every step through the vault or the Zap carries its gas limit. Nothing is signed or sent: simulate the steps with preview_steps, then send them from the wallet.

  • actions.preview unknown never probed

    Simulate a list of transactions in sequence against the latest Base block, as if the wallet sent them one after the other, before anything is signed. Each step sees the state the previous ones left (an approval before a mint works). Returns, per step, whether it would succeed, the gas it uses, whether the gas limit it carries is enough, and the decoded revert reason with a hint when it fails; and the net token and ETH movements for the wallet. Pass the steps exactly as prepare_action, invest_usdc_to_gblin or swap_gblin_to_usdc_jit return them. State can change before your transactions land: a successful preview is evidence, not a guarantee.

  • payments.prepare unknown never probed

    Build a gasless GBLIN payment. The vault's share token implements EIP-3009, so the holder signs an authorization and anybody can carry it on chain: the payer needs no ETH. Returns the EIP-712 message to sign (its domain is read from the token, not assumed), the calldata that carries the signed authorization, and the x402 'exact' payload for paying an HTTP endpoint in GBLIN. Use method 'receive' when paying a known recipient: only that recipient can submit it, so nobody can front-run the transfer. Use 'transfer' for an x402 facilitator, which submits on the seller's behalf. With relay: true it also prepares the fee authorization for relay_gblin_payment, for when nobody else will carry the payment. No private key is requested, held or transmitted: the signature is produced by the caller's own wallet.

  • payments.verify unknown never probed

    Check a signed GBLIN authorization against the chain before spending gas on it. Recovers the signer from the EIP-712 digest (and asks the wallet itself through ERC-1271 when the payer is a contract), then checks the validity window against on-chain time, whether the nonce has already been used or cancelled, and whether the payer still holds the amount. Returns a verdict and the ready calldata when it would settle, the failing reason when it would not. This is the same set of checks an x402 facilitator runs, so a 'would_settle' verdict here means the payment is good to carry.

  • attestation.verify unknown never probed

    Verify a GBLIN Risk Attestation — the object returned by GBLIN's /api/x402/attestation, or a proof-of-diligence a peer agent attached to its action. FREE, no payment. Runs four checks: (1) INTEGRITY — recomputes the EIP-712 attestation_id and detects tampering; (2) AUTHENTICITY — if a signature is present, recovers the signer and checks it is GBLIN's published attestor; (3) FRESHNESS — whether it expired (10-minute TTL), using on-chain time; (4) LIVE DRIFT — compares the attested regime to the CURRENT on-chain regime and flags if it changed. Use before you trust any counterparty/peer that claims it 'checked market risk via GBLIN'.

  • search unknown never probed

    Search GBLIN's documentation and live state and return matching documents: the agent API summary, the protocol's README and documents (governance, deployments, review record), the MCP server and library READMEs, the public pages, one card per MCP tool, and a snapshot of the live vault state. Returns {results: [{id, title, url}]}; pass an id to fetch for the full text. Read-only and free.

  • fetch unknown never probed

_ 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ 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.
