Sestra is a privacy-first access middleware that converts verified usage requirements into short-lived API access without storing identity handling funds, or increasing compliance scope.
Modern APIs are increasingly consumed by automated systems — services, agents, and backend processes rather than human users. Yet access control and monetization models still depend on accounts, identities, and long-lived credentials.
This mismatch introduces friction, unnecessary data exposure, and operational overhead for teams that simply want to control access based on verified conditions.
Sestra was created to close this gap.
Systems, agents, and backend jobs are forced into human-centric models built around users, logins, and credentials.
Storing accounts, identifiers, and usage history expands your risk surface and long-term data liability.
Connecting access, billing, and compliance often means building and maintaining infrastructure far outside your core product.
Modern APIs are consumed programmatically and variably, but pricing still assumes fixed plans and long-lived access.
Sestra turns verified conditions into short-lived access sessions through a clear, auditable flow.
Policy-Driven Authorization
All access rules in Sestra are defined through policies, allowing access behavior to change without code rewrites.
Session-Based Access Control
Sestra replaces long-lived API keys and user accounts with short-lived access sessions that expire automatically.
Event-Based Integration
Sestra communicates with backends through events rather than blocking calls, including access requests and session lifecycle updates.
Agent-First Architecture
Sestra treats autonomous agents and backend services as first-class clients, enabling access flows without accounts or credentials.
SOLUTION LAYER
Sestra operates between your API and external verification mechanisms, evaluating whether defined conditions are met and issuing short-lived access sessions — no more, no less.
Grant access only when predefined requirements are satisfied — without becoming part of the transaction flow or holding funds.
