Kael scores every agent wallet on-chain. Query the Known Agent Trust (KAT) Score API before you transact. Start free — 100 queries included, no credit card required.
Your first 100 queries are free. After that you will be charged $0.005 per KAT Score automatically. No credit card needed until then.
Autonomous payments are already happening at machine speed across multiple networks. The trust layer hasn't caught up.
Agent-to-agent commerce is live.
Coinbase x402, Stripe MPP, and BNB ERC-8004 enable autonomous
transactions at machine speed — no human in the loop.
Identity is an address.
Agents don't have credentials, reputation scores, or credit histories.
Every counterparty is an anonymous wallet.
How do you know if it can be trusted?
When your agent transacts with an unknown counterparty,
the on-chain record is the only signal you have.
If you are building or operating autonomous agents that transact on-chain, KAT Score is the trust layer your stack is missing.
Bittensor Subnet Operators
Score the agent wallets interacting with your subnet before they participate.
Protect your subnet economy from malicious or unreliable agent counterparties.
Agent Infrastructure Builders
Building on Coinbase x402, Stripe MPP, or BNB ERC-8004? Wire KAT Score into
your agent's transaction flow as a pre-flight trust check. One API call before
every transaction.
DeFi Protocol Teams
As autonomous agents become your heaviest users, know which agent wallets have
proven behavioral track records and which are unverified newcomers.
Agent Wallet Operators
Running agents that transact at scale? Query your own KAT Score to understand
how counterparties see you and monitor your score over time as your on-chain
history grows.

Kael analyses on-chain behaviour and returns a structured trust score in milliseconds — ready to act on programmatically.
POST /api/v1/score with any supported wallet address
and your API key. Supports 10 chains: Ethereum, Base, Polygon,
BNB Smart Chain, Arbitrum, Bitcoin, Solana, Avalanche, Hyperliquid, and Bittensor (TAO).
Behavioural consistency, transaction legitimacy, wallet age & history, counterparty quality, and volume stability — each scored 0–20, analysed by a purpose-built AI scoring engine using on-chain transaction data.
A structured JSON response with the overall score, bond-style grade (AAA to CCC), confidence level, dimension breakdown, and plain-English reasoning — under 10ms for cached scores, under 5 seconds for fresh on-chain analysis.
One API call before you transact. Your existing code stays exactly as it is.

Established wallet with 2+ years of consistent on-chain activity. Regular interaction patterns with reputable protocols. Counterparty quality slightly reduced by two unverified contract interactions in Q3. Overall profile is consistent with a legitimate autonomous agent.
Professional wallet intelligence at a fraction of enterprise compliance pricing. Built for developers, priced for builders.
KaelAi delivers scored, analysed, and graded trust intelligence per response — not raw data. Every query returns a complete KAT Score with five dimension breakdown, bond-style grade, confidence level, and plain-English reasoning.
