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.

Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly

_ what it can do 10 tools
9 paid 1 never probed 9 of 10 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.

  • costo-giro 0.01 31566704 paid never probed

    Before an ALGO/USDC swap on Algorand: what a full round trip actually costs at your size. Measured slippage, fees and price impact at $100 / $1000 / $5000 from live DEX pools - the measured end-to-end effect, not the declared fee. Refreshed 3x/day. Use it to size a trade or check a quote.

    algoranddexslippageprice-impactx402-global-challenge

  • soglia-viva 0.02 31566704 paid never probed

    Is the ALGO/USDC gap between Algorand's two main pools worth attention right now? Returns the two-leg arbitrage break-even threshold in basis points, recomputed from real on-chain reserves at every reading, and the observed gap. Gap below threshold = no opportunity. Screening, not an execution trigger.

    algoranddexarbitragebreak-evenx402-global-challenge

  • pool-onchain 0.01 31566704 paid never probed

    Check an aggregator's ALGO/USDC liquidity against the chain. Returns the reserves of Algorand's two main AMM pools read directly from the pool accounts, the implied price per pool, and the measured gap between aggregator-declared and recomputed liquidity - the check, not someone else's number.

    algoranddexliquidityamm-reservesx402-global-challenge

  • mercato-algo 0.01 31566704 paid never probed

    Cross-check an ALGO/USDC price before you act on it. Returns the price implied by the on-chain AMM reserves of Algorand's two main pools, the measured divergence across three independent external sources (the measurement, never their numbers), and the current network fee. Refreshed 3x/day.

    algoranddexprice-divergencecross-source-checkx402-global-challenge

  • costo-giro-storico 0.05 31566704 paid never probed

    Reconstruct what an ALGO/USDC swap cost on a past date, or audit a past execution. Full historical series of the measured round-trip cost (slippage and fees) by trade size on Algorand DEX pools, one entry per probe run since 26 July 2026, in one call. Yesterday's quotes cannot be asked again.

    algoranddexslippagehistorical-datax402-global-challenge

  • divario-storico 0.05 31566704 paid never probed

    Answer, for a past window, whether an ALGO/USDC two-leg arbitrage on Algorand was ever worth doing. Full series of the break-even threshold against the observed pool gap, reading by reading since 26 July 2026, in one call. The reserves of the past cannot be re-read from the chain.

    algoranddexarbitragehistorical-datax402-global-challenge

  • stabilita-costo-giro 0.02 31566704 paid never probed

    Decide whether one ALGO/USDC cost reading is enough to act on. Minimum, maximum, mean and latest measured round-trip cost by trade size across the whole series recorded on Algorand DEX pools since 26 July 2026 - the spread tells you if a single quote is dependable or moves too much to trust.

    algoranddexslippagecost-stabilityx402-global-challenge

  • storico-firmato 0.05 31566704 paid never probed

    The measured historical series - round-trip cost, arbitrage break-even, or cost-stability - Ed25519-signed over canonical JSON as a portable, independently verifiable artifact. One entry per probe run since 26 July 2026. Reserve history cannot be rebuilt from free endpoints after the fact: this exists because we archived it. Measured, not estimated. Choose with ?series=cost-roundtrip|arb-gap|cost-stability.

    algoranddexhistorical-datasigned-attestationx402-global-challenge

  • attesta-slippage 0.02 31566704 paid never probed

    Signed pre-trade attestation of ALGO/USDC swap cost, measured from live AMM reserves at an exact Algorand round. For your size (or a standard grid): reserve-implied output, effective price and price impact on the two main pools, Ed25519-signed over canonical JSON with round, reserves and method URL - a portable, independently re-executable measurement. Reserves change every block: this attests the state at the stated round, it does not predict your fill.

    algoranddexslippagesigned-attestationx402-global-challenge

  • free-sample unknown never probed

    Latest measured ALGO/USDC round-trip cost at the $100 size, free, in the same envelope as the paid products.

_ 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
85%

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.
