How this service works
Signed verdict: is this action (action, amount, currency, counterparty, payment instrument) inside the agent's mandate and is the credential active? Evaluates the reserved mandate fields; lists the fields it did not evaluate.
Output
A signed verdict object confirming whether the action, amount, currency, and counterparty are within the agent's mandate and whether the credential is currently active, along with a list of mandate fields that were not evaluated in this check.
Example use cases
Pre-payment mandate check for autonomous agent
“I'm about to have my agent send a payment of 1000 BRL to the supplier domain fornecedor.com.br — first check if agent credential cred_xyz is authorized for that action and amount, and confirm its credential hasn't expired.”
Daily spend limit compliance verification
“My agent wants to make another payment today totaling 200 USDC — it's already spent 150 USDC today. Check agent cred_abc to see if this action is still within its mandate given the spent_today amount of 150 USDC.”
Counterparty wallet address authorization check
“Before my agent interacts with wallet address 0xABCDEF1234567890, verify that credential cred_789 permits actions toward that counterparty and that the credential is currently active.”
Technical details
Endpoint
GEThttps://kya-br-agents.marcelfons.workers.dev/v1/agents/:id/allowed?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a cryptographically signed, auditable mandate-check before an AI agent executes a financial or operational action in a Brazilian business context. Prefer this over generic auth checks when you need explicit Brazilian CNPJ counterparty validation, per-action and per-amount mandate scoping, and a signed verdict that can be logged for compliance purposes.
Side effects
- Agent credential ID not found — returns an error indicating the credential does not exist
- Credential expired — verdict indicates credential is inactive
- Missing required path parameter 'id' — returns validation error
- Query parameters malformed (e.g. invalid CNPJ format) — may return partial evaluation with unevaluated fields
- Action or currency not recognized — returned in unevaluated fields list
- x402 payment not included or invalid — returns 402 Payment Required before processing
