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.

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.

_ what it can do 7 tools
1 open 6 never probed 1 of 7 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.

  • list_markets open 17h 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.

    arguments 5 lines
  • get_market unknown never probed

    Full detail for a single market: chain, curve address, supply, fee rates, current price in the chain's native asset, and which read path serves its trade history. Free.

  },

}
    arguments 15 lines
  • quote_buy 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.

  • how_to_pay unknown never probed

    The exact steps to turn a 402 challenge into a settled cross-chain buy: what to sign, which chain settles, and which header carries the payment. Free. Read this if you have never paid an x402 endpoint before.

    arguments 5 lines
  • buy_token unknown never probed

    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.

    arguments 24 lines
  • pay_and_buy 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.

  • trade_history unknown never probed

    Trade history for a market, newest first, with an explicit statement of whether it reaches the launch block. Free. Monad is served by our Envio indexer, which has no lookback window; the other chains are served by a log scan whose reach is reported per call. When the scan cannot reach the launch block the answer says so instead of presenting a shortened list as the whole history.

_ 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.

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 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.
