api record

ADEXTO sells positions in bonding-curve markets across chains, paid for with USDC on Base over x402. Call list_markets to see what exists, quote_buy to price one without paying, then buy_token with a signed payment. You never need gas on the destination chain and never need to bridge. Every tool except buy_token is free, and buy_token's first response is a 402 challenge, which is expected rather than a failure. A ticker can trade on more than one chain: pass chainId from list_markets to pick one. Every market can be staked, in its own stake contract or its chain's stake hub, and a stake opens…

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.

  • list_markets reads open 9h ago

    Every bonding-curve market this gateway can sell, across all chains it serves, with its ticker, chain, curve address and whether it is currently tradable. Free. Start here: the buy tools require a ticker and deliberately have no default.

  • check_stake reads unknown 6h ago

    Free. Reads the market's stake contract on its own chain: its own AdextoAgentStake where it has one, otherwise the chain's AdextoStakeHub, which accepts every other market launched through ADEXTO from its first block. Returns how much an address has staked, the minimum, whether the position is active (at or above the minimum), and the totals. An active stake opens ask_agent for that market and an Agent Compute API key (see get_market staking.unlocks). There is no lock and no reward: unstake works at any time.

  • ask_agent reads unknown 6h ago

    Asks the market's own agent a question about that market. Open to an address whose stake in the market's stake contract is active (check_stake), proven with a signed access_message. The answer comes from glm-5.3 on the 0G router and is limited to facts read on-chain for this call; the tool returns those facts next to the answer. Refused without an active stake, and nothing is charged either way.

  • quote_buy reads unknown never probed

    Reads the gateway's HTTP 402 challenge for a market and returns the quote and payment requirements without spending anything. The challenge carries the exact amount, the asset, the payTo address and the EIP-3009 domain, so an agent can decide before it signs. Free. This is the tool to call before buy_token.

    Executes the buy. Called without xPayment it returns the HTTP 402 challenge, which is the correct first response and not an error. Called with a signed x402 payload in xPayment it settles on Base and the curve on the destination chain sends the tokens straight to `to`. You never need native gas on the destination chain and never need to bridge.

  • pay_and_buy moves money unknown never probed

    Buys a market for real, completing the step an LLM cannot do alone: signing the EIP-3009 USDC authorisation. IMPORTANT for honest reporting — the signature is made by the operator's wallet on the server, not by a wallet you control, so describe the result as 'executed the purchase', not 'paid from my own funds'. Refuses unless the caller carries the agent key, and refuses any quote whose asset, network, recipient or amount does not match the hard-coded limits. Delivery always goes to the signer.

  • prepare_launch reads unknown never probed

    Launch a new ADEXTO market without handing over a key. Call it once without a signature: it checks the ticker, the chain and an optional ERC-8004 agent you own, and returns an attestation message for the deployer to sign (EIP-191). Call it again with the same arguments plus attestationMessage and attestationSignature: it anchors the launch metadata and returns the unsigned deployTrinity transaction (value 0, gas only), simulated from your address, with a gas estimate. Fee preset: 1.00% per trade, 0.70% to the creator. All supply goes into the curve; the creator gets no allocation. After the transaction is mined, call register_launch. The attestation message ends with an acceptance of the ADEXTO Terms and Acceptable Use Policy (adexto.xyz/terms): signing it is the deployer's acceptance, and markets that break the policy are removed from ADEXTO.

  • trade_history reads unknown 9h ago

    Trade history for a market, newest first, with an explicit statement of whether it reaches the launch block. Free. Monad, Robinhood Chain and Arc are served by our Envio indexer and Base and Arbitrum One by our subgraph, both complete from the launch block; every market is also covered by our per-market index of every swap since launch, joined to a live log scan for the newest fills. When a market's index is still catching up or a read fails, the answer says so instead of presenting a shortened list as the whole history. Treasury buybacks are not trades and are not listed, although the curve's swapCount counts them.

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 6a199bbe2fae459d.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/6a199bbe2fae459d/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 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.
