TypeScript SDK

Installation

npm install @axonflow/sdk

Client Setup

import { AxonFlow } from '@axonflow/sdk';

const client = new AxonFlow({
  endpoint: 'http://localhost:8080',
  clientId: 'my-tenant',
  clientSecret: 'my-secret',  // Optional for self-hosted
});

List Policies

// List all policies
const policies = await client.listStaticPolicies();

// With filters
const filtered = await client.listStaticPolicies({
  tier: 'system',
  category: 'security-sqli',
  enabled: true,
  limit: 50,
  offset: 0,
});

// Response type
interface StaticPolicy {
  id: string;
  name: string;
  description?: string;
  category: string;
  tier: 'system' | 'organization' | 'tenant';
  pattern: string;
  action: 'block' | 'redact' | 'warn' | 'log';
  severity: 'critical' | 'high' | 'medium' | 'low';
  enabled: boolean;
  hasOverride?: boolean;
}

Get Single Policy

const policy = await client.getStaticPolicy('sys_sqli_union_select');
console.log(policy.pattern);  // (?i)\bUNION\s+(ALL\s+)?SELECT\b

Create Policy

// Use an existing category that best fits your use case
const policy = await client.createStaticPolicy({
  name: 'Block Internal IPs',
  description: 'Prevent exposure of internal IP addresses',
  category: 'security-admin',  // security-sqli, security-admin, pii-global, pii-us, pii-eu, pii-india, code-secrets, code-unsafe, code-compliance
  pattern: '\\b10\\.\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}\\b',
  action: 'block',
  severity: 'medium',
  enabled: true,
});

console.log(`Created policy: ${policy.id}`);

Update Policy

const updated = await client.updateStaticPolicy('my-policy-id', {
  enabled: false,
  action: 'warn',
});

Delete Policy

await client.deleteStaticPolicy('my-policy-id');

Toggle Policy

// Disable
await client.toggleStaticPolicy('my-policy-id', false);

// Enable
await client.toggleStaticPolicy('my-policy-id', true);

Get Effective Policies

const effective = await client.getEffectiveStaticPolicies({
  category: 'pii-global',
  includeDisabled: false,
});

Test Pattern

const result = await client.testPattern({
  pattern: '\\b[A-Z]{5}[0-9]{4}[A-Z]\\b',
  inputs: [
    'My PAN is ABCDE1234F',
    'No PAN here',
  ],
});

console.log(result.matches);
// [{ input: 'My PAN is ABCDE1234F', matched: true, matchedText: 'ABCDE1234F' }]

Python SDK

Installation

pip install axonflow

Client Setup

from axonflow import AxonFlow

client = AxonFlow(
    endpoint="http://localhost:8080",
    client_id="my-tenant",
    client_secret="my-secret",  # Optional for self-hosted
)

List Policies

# List all policies
policies = await client.list_static_policies()

# With filters
filtered = await client.list_static_policies(
    tier="system",
    category="security-sqli",
    enabled=True,
    limit=50,
)

for policy in filtered:
    print(f"{policy.name}: {policy.action}")

Get Single Policy

policy = await client.get_static_policy("sys_sqli_union_select")
print(policy.pattern)

Create Policy

# Use an existing category that best fits your use case
policy = await client.create_static_policy(
    name="Block Internal IPs",
    description="Prevent exposure of internal IP addresses",
    category="security-admin",  # security-sqli, security-admin, pii-global, pii-us, pii-eu, pii-india, code-secrets, code-unsafe, code-compliance
    pattern=r"\b10\.\d{1,3}\.\d{1,3}\.\d{1,3}\b",
    action="block",
    severity="medium",
    enabled=True,
)

print(f"Created policy: {policy.id}")

Update Policy

updated = await client.update_static_policy(
    policy_id="my-policy-id",
    enabled=False,
    action="warn",
)

Delete Policy

await client.delete_static_policy("my-policy-id")

Sync Usage

The Python SDK supports both async and sync usage patterns:

# Synchronous usage (blocking)
from axonflow import AxonFlow

client = AxonFlow.sync(
    endpoint="http://localhost:8080",
    client_id="my-tenant",
    client_secret="my-secret",
)

# All methods work synchronously — no await needed
policies = client.list_static_policies()
for policy in policies:
    print(f"{policy.name}: {policy.action}")

policy = client.create_static_policy(
    name="Block Internal IPs",
    description="Prevent exposure of internal IP addresses",
    category="security-admin",
    pattern=r"\b10\.\d{1,3}\.\d{1,3}\.\d{1,3}\b",
    action="block",
    severity="medium",
    enabled=True,
)
print(f"Created: {policy.id}")

Async Usage

import asyncio
from axonflow import AxonFlow

async def main():
    client = AxonFlow(
        endpoint="http://localhost:8080",
        client_id="my-tenant",
        client_secret="my-secret",
    )

    # All methods return coroutines — use await
    policies = await client.list_static_policies(
        tier="system",
        category="security-sqli",
    )

    # Concurrent operations with asyncio.gather
    sqli_policies, pii_policies = await asyncio.gather(
        client.list_static_policies(category="security-sqli"),
        client.list_static_policies(category="pii-global"),
    )

    print(f"SQLi: {len(sqli_policies)}, PII: {len(pii_policies)}")

asyncio.run(main())

<dependency>
    <groupId>com.getaxonflow</groupId>
    <artifactId>axonflow-sdk</artifactId>
    <version>4.3.0</version>
</dependency>

import com.getaxonflow.sdk.AxonFlow;
import com.getaxonflow.sdk.AxonFlowConfig;

AxonFlow client = AxonFlow.create(AxonFlowConfig.builder()
    .endpoint("http://localhost:8080")
    .clientId("my-tenant")
    .clientSecret("my-secret")
    .build());

    .enabled(true)
    .limit(50)
    .build();

List<StaticPolicy> filtered = client.listStaticPolicies(options);

    .enabled(false)
    .action(PolicyAction.WARN)
    .build();

StaticPolicy updated = client.updateStaticPolicy("my-policy-id", update);

Delete Policy

client.deleteStaticPolicy("my-policy-id");

Error Handling

All SDKs throw/return errors for common scenarios:

Error	Description
`AxonFlowError` / `AxonFlowException`	Base error for all SDK errors
`AuthenticationError` / `AuthenticationException`	Invalid or missing credentials
`PolicyViolationError` / `PolicyViolationException`	Request blocked by policy
`RateLimitError`	Rate limit exceeded (Python/TypeScript/Go)

TypeScript Example

import { AxonFlowError } from '@axonflow/sdk';

try {
  await client.deleteStaticPolicy('sys_sqli_union_select');
} catch (error) {
  if (error instanceof AxonFlowError) {
    if (error.statusCode === 403) {
      console.log('Cannot delete system policies');
    } else if (error.statusCode === 404) {
      console.log('Policy not found');
    } else {
      console.error(`Unexpected error: ${error.message}`);
    }
  }
}

TypeScript Async/Await Pattern

All TypeScript SDK methods return Promises and should be used with async/await:

async function managePolicies() {
  const client = new AxonFlow({
    endpoint: 'http://localhost:8080',
    clientId: 'my-tenant',
  });

  // Sequential operations
  const policy = await client.createStaticPolicy({
    name: 'Block Test Pattern',
    category: 'sensitive-data',
    pattern: '\\btest_data\\b',
    action: 'warn',
    severity: 'low',
    enabled: true,
  });

  // Concurrent reads with Promise.all
  const [systemPolicies, tenantPolicies] = await Promise.all([
    client.listStaticPolicies({ tier: 'system' }),
    client.listStaticPolicies({ tier: 'tenant' }),
  ]);

  console.log(`System: ${systemPolicies.length}, Tenant: ${tenantPolicies.length}`);
}

Go Example

import "errors"

err := client.DeleteStaticPolicy("sys_sqli_union_select")
if err != nil {
    var httpErr *axonflow.HTTPError
    if errors.As(err, &httpErr) {
        switch httpErr.StatusCode {
        case 403:
            log.Println("Cannot delete system policies")
        case 404:
            log.Println("Policy not found")
        default:
            log.Printf("HTTP error %d: %s", httpErr.StatusCode, httpErr.Message)
        }
    } else {
        // Network or other non-HTTP error
        log.Printf("Unexpected error: %v", err)
    }
}

Python Example

from axonflow.exceptions import AxonFlowError, AuthenticationError, PolicyViolationError, RateLimitError

try:
    await client.delete_static_policy("sys_sqli_union_select")
except AuthenticationError:
    print("Invalid credentials")
except PolicyViolationError:
    print("Cannot delete system policies")
except AxonFlowError as e:
    print(f"Error: {e}")

Java Example

import com.getaxonflow.sdk.exceptions.AxonFlowException;
import com.getaxonflow.sdk.exceptions.AuthenticationException;
import com.getaxonflow.sdk.exceptions.PolicyViolationException;

try {
    client.deleteStaticPolicy("sys_sqli_union_select");
} catch (AuthenticationException e) {
    System.out.println("Invalid credentials");
} catch (PolicyViolationException e) {
    System.out.println("Cannot delete system policies");
} catch (AxonFlowException e) {
    System.out.println("Error: " + e.getMessage());
