A-Identity

The passport and wallet for AI agents: KYA, reputation checks, and onchain spend limits.

A-Identity provides KYA verification, portable onchain reputation, and smart contract stablecoin spend limits before any AI agent payment settles.

Counterparty Verification & KYA

Before an AI agent pays an API, shop, or another agent, A-Identity verifies who the counterparty is, proves wallet control onchain, and evaluates real payment and delivery history rather than easily faked reviews.

A-Identity returns a deterministic verdict in ~1 second per payment: ALLOW (verified seller), WARN (new seller), DENY (check failed), or ASK A HUMAN (above limit).

Stablecoin Spend Vaults

A-Identity complements agent wallets and x402 payment rails by enforcing daily and per-call stablecoin spending caps inside smart contracts, ensuring a changed prompt or leaked key can never raise its own limit.

Key Features:

  • One-line integration via npm (@a-identity/trust-guard) or MCP server (a-identity.xyz/mcp).
  • Built on open standards: ERC-8004 for onchain identity, x402 for machine-to-machine payments, and stablecoins for native settlement.
  • Pay-per-check in stablecoins ($1–$10) with a free verdict preview, or predictable monthly plans for finance teams.
  • Immutable transaction-hash receipts ready for month-end finance audits.

Built For:

  • Finance teams whose agents buy APIs, market data, and compute.
  • API marketplaces and autonomous agent platforms requiring automated vendor KYB and spend governance.
  • AI agent developers building on Arc, programmable wallets, and x402.

Use Cases

KYA (Know Your Agent) & Counterparty Verification

Before an AI agent pays an API, data provider, or another agent in stablecoins, A-Identity checks who the counterparty is, verifies onchain wallet ownership, and scores its historical transaction and delivery track record on ERC-8004 registries. This helps prevent agents from paying lookalike sellers or unverified endpoints.

Contract-Enforced Stablecoin Spend Vaults

Finance teams and developers can set daily and per-transaction stablecoin spending caps inside smart contract Spend Vaults rather than application code. Even if an agent's prompt is manipulated or its key is compromised, the agent can never raise its own limit - any payment above the cap is automatically refused or held for human approval.

One-Line Trust Guard for x402 & Agent Wallets

Developers can drop A-Identity in front of agent wallets and x402 payment rails using a single line of code via our npm package (@a-identity/trust-guard). Every payment request returns a clear ALLOW, WARN, DENY, or ASK A HUMAN verdict in about one second before stablecoins move.

MCP-Native Policy & Human-on-the-Loop Approvals

Connect any MCP-compatible AI agent or workflow via a-identity.xyz/mcp. Low-risk, verified sub-cent stablecoin payments settle autonomously at machine speed, while high-value or unfamiliar counterparties trigger an "Ask a Human" workflow so finance and operations teams stay in control.

Automated Audit Trails & Receipts for Finance Teams

Agent payments are sub-cent, nonstop, and final with no chargebacks. A-Identity turns every verified stablecoin settlement into an auditable receipt carrying its onchain transaction hash, replacing manual vendor vetting and bookkeeping for AI-native finance teams at month-end.

Batch Auditing for Agent Marketplaces & Wallet Providers

Service marketplaces, API directories, and wallet providers in the stablecoin and x402 ecosystems can use A-Identity to KYA-attest listed agents in batch. Every verified payment builds a portable, cross-chain reputation record across Arc and seven additional mainnet networks.
