Platform Infrastructure

APIs And SDKs Built For Financial Correctness

Build against contracts designed for long-lived integrations, production observability, and replay-safe money movement under real-world failure conditions.

Every integration starts from stable contracts, typed errors, idempotency, and request-level observability.

Entrypoint

GET /v1

01Auth

Authenticate request

API keys, scopes, and tenant context are resolved before capability logic.

02Shape

Validate schema

Typed request and error contracts keep integrators out of guesswork.

03Guard

Resolve idempotency

Money-writing calls check replay posture before side effects.

04Trace

Correlate response

Request identifiers connect API behavior to events, logs, and support context.

05Evolve

Version without drift

Contract changes remain compatible with long-lived integrations.

Events emitted

Fig 02failure paths

Failure paths stay inspectable.

The capability exposes incident, system path, and evidence posture so teams can reason about production behavior.

Proof 01

Incident

Control-plane tooling enforces modern route contracts and rejects legacy path drift.

Zentra path

State transitions, events, and review ownership remain explicit.

Evidence

Proof 02

Incident

Developer surfaces include API keys, logs, routing context, and sandbox workflows.

State transitions, events, and review ownership remain explicit.

Fig 03api to product state

The integration creates visible state.

One call to GET /v1 produces status, emitted events, and retained evidence a team can inspect without leaving the product surface.

inspect requestrequest
const zentra = new Zentra({
  apiKey: process.env.ZENTRA_SECRET_KEY
})

await zentra.requests.retrieve("req_8172")

01

Versioned API contracts

Protect existing integrations with backward-compatible evolution patterns.

02

Typed integration boundaries

Use typed request and response schemas for predictable integration behavior.

03

Idempotency-first writes

Protect money-affecting operations from replay and duplicate submission side effects.

04

Operational traceability

Correlate requests and outcomes across services to speed up diagnosis and support.

Developer proof

Code, contract, and event-runtime evidence rendered in one technical view.

Fig 05operational proof

Evidence that holds when production gets noisy.

State, actor, tenant, signature, and policy context remain reviewable after the happy path breaks — written to be checked by operators and compliance teams, not admired in a deck.
