⚪verify_agent(agent_address)
Verify an AI agent's on-chain legal identity on Tracea (Base Sepolia). Returns registration status, financial cap, permission scope, revocation status, and KYA legal identity (mandant) when available. Use this BEFORE trusting or delegating work to an agent.

}⚪report_activity(agent_address, category, summary, permission_label, in_permission, ...)
Report an action the agent just performed to its owner's Tracea activity feed (off-chain, free, instant). Call this AFTER every significant action (email sent, message posted, file modified, payment, purchase, booking...). Auth via the Tracea MCP URL (?key=...) from the agent's identity page, OR self-activate with a one-time activation code (?code=... or x-activation-code header) — the tool then receives its apiKey automatically.

}🟡get_my_identity(agent_address, activation_code)
Get this agent's full Tracea identity (activity apiKey +, for v2 agents, its EOA private key and ERC-4337 smart account address) using a one-time activation code from the owner. The private key is returned ONLY ONCE — save it securely.

}🟢get_payment_whitelist(agent_address)
Get the list of owner-approved payment destination addresses for an agent (anti-injection guardrail). Non-empty list = the agent's smart account can ONLY pay these addresses. Empty = all allowed.

"$schema": "http://json-schema.org/draft-07/schema#"
}🟢check_payment_allowed(agent_address, destination, amount_eth)
Dry-run a payment BEFORE executing it: checks on-chain whether the agent's smart account would allow it (permission granted, within financial cap, destination approved if a whitelist exists). Returns { allowed, reason }.

{
"type": "object",
"properties": {

"$schema": "http://json-schema.org/draft-07/schema#"
}🟡payment_required(destination, amount_usdc, resource, agent, ttl_seconds)
Create a x402 payment request (HTTP 402) for a resource you sell to another agent. Returns a paymentId, the USDC amount in units, the destination address and the TraceaPayments contract to call. The paying agent must then call TraceaPayments.payX402(destination, amount, paymentId) on-chain — the contract enforces financial cap + whitelist on-chain. Deliver the resource only after payment_incoming confirms fulfilment.

"$schema": "http://json-schema.org/draft-07/schema#"
}⚪payment_incoming(payment_id, tx_hash)
Verify a x402 payment ON-CHAIN (the USDC transfer to your address, exact amount) and mark the session fulfilled. The blockchain is the ONLY source of truth — the payment_sessions table is never trusted alone. Returns { status: 'fulfilled', resource } if verified, or an error if not yet paid/expired.

"$schema": "http://json-schema.org/draft-07/schema#"
}🟢payment_status(payment_id)
Get the status of a x402 payment session (pending | paid | fulfilled | expired), with destination, amount and tx hash. Useful to poll while waiting for the paying agent's on-chain transaction.
