Your agents need credentials to work. They should never see them.
AI agents are most useful when they can act on your behalf -- calling APIs, processing payments, connecting to services. But every credential you hand to an agent becomes an attack surface.
A compromised agent with raw API keys can exfiltrate data, drain accounts, or make unauthorized purchases. Even well-behaved agents store credentials in memory, logs, or configs where they can leak. The industry's current answers -- "just trust the agent" or "never give it access" -- leave you choosing between productivity and safety.
Embedding API keys in prompts, configs, or environment variables means any agent compromise exposes every connected service. Keys cannot be rotated without redeploying the agent.
Giving agents credit card numbers or wallet private keys creates unlimited spending exposure. A single prompt injection can trigger unauthorized charges.
Agents that receive credentials in plaintext hold them in context windows, logs, and debug traces -- all of which can be extracted or persisted beyond the session.
Loading wallets or prepaid accounts with large balances means the entire balance is at risk if the agent or its runtime is compromised.
Credentials are encrypted at rest and in transit. Agents reference credential IDs -- never raw secrets. Even if an agent's context is leaked, no usable credentials are exposed.
AgentPMT executes API calls and service connections on behalf of your agents. The credential is decrypted server-side at the moment of use and never enters the agent runtime.
Payment credentials are governed by budget limits enforced cryptographically via smart contracts and server-side rules. Agents physically cannot exceed the caps you set.
Sensitive operations trigger push notifications to your mobile device. You review the exact action, merchant, and amount before biometric approval. Card details never touch the agent.
Every credential access, API call, and payment attempt is logged with timestamps, agent identity, and outcome. Review activity from the dashboard at any time.
Revoke any credential or agent's access in one click from the dashboard. No agent code changes, no redeployment, no coordination. Access stops immediately.
| Approach | Credentials Exposed | Spending Limits | Revocation Speed | Audit Trail |
|---|---|---|---|---|
| Raw credentials to agent | Yes -- full plaintext | None unless hand-coded | Requires agent redeployment | Manual / none |
| Self-hosted proxy | Reduced, but you maintain infra | Custom implementation required | Depends on your setup | Custom implementation |
| AgentPMT | Never -- encrypted vault + proxy | Built-in, contract-enforced | Instant, one-click | Built-in, every action logged |
Yes. Agents reference credential IDs, and AgentPMT handles execution. From the agent's perspective, it sends a request and receives the result -- it never needs to see or store the actual secret.
The attacker gets credential IDs, not secrets. IDs alone cannot call external services. You can revoke the agent's access from the dashboard instantly, and no credentials need to be rotated.
Credit card charges require your mobile approval with biometric verification before they execute. Stablecoin payments are governed by on-chain smart contracts (x402Direct) with hard caps and reset periods that the agent cannot override.
Yes. Revoking a credential or disconnecting an agent from the dashboard takes effect immediately. The agent's next request will be denied, no code changes or redeployment needed.
API keys, OAuth tokens (with automatic refresh handling), payment methods (credit cards and stablecoin wallets), and custom service credentials. The encrypted vault handles any key-value secret.
Traditional secrets managers store and retrieve secrets -- the consuming application still sees the plaintext. AgentPMT's vault combines storage with proxy execution: the secret is never delivered to the agent. It is decrypted only at the moment AgentPMT makes the API call on the agent's behalf.
