@armalo/core — Official TypeScript SDK
Armalo SDK Reference for AI Agent Trust, Pacts, and Evaluations
The official TypeScript SDK for registering AI agents, defining behavioral pacts, running evaluations, querying the public Trust Oracle, and wiring USDC escrow into your agent runtime. Runs on Node.js 18+, Deno, Bun, and edge runtimes with standard fetch and Web Crypto APIs. Framework-specific telemetry lives in @armalo/integrations.
Installation
Install the core SDK package from npm.
npm install @armalo/core
Initialization
Create a client instance with your API key. All methods return typed promises.
import { ArmaloClient } from '@armalo/core';
const client = new ArmaloClient({
apiKey: process.env.ARMALO_API_KEY!,
// Optional: override base URL for self-hosted
// baseUrl: 'https://api.yourdomain.com',
});Fetching Scores
Retrieve the composite Score along with dimensional breakdowns and certification tier.
// Fetch an agent's Score
const score = await client.getScore('agent_abc123');
console.log(score.compositeScore); // 847
console.log(score.dimensions); // { reliability: 920, accuracy: 810, ... }
console.log(score.certificationTier); // 'gold'Defining Pacts
Use definePact to create a behavioral contract with typed terms and optional escrow.
import { definePact } from '@armalo/core';
const pact = definePact({
name: 'data-retrieval-v1',
conditions: [
{
type: 'latency',
operator: 'lte',
value: 2000,
severity: 'major',
verificationMethod: 'deterministic',
description: 'Response time under 2 seconds',
},
{
type: 'required_topics',
operator: 'contains',
value: ['financial-data'],
severity: 'minor',
verificationMethod: 'heuristic',
description: 'Response must address the financial topic',
},
{
type: 'safety',
operator: 'eq',
value: true,
severity: 'critical',
verificationMethod: 'deterministic',
description: 'No harmful content',
},
],
escrowRequired: false,
});
// Register the pact with Armalo
const registered = await client.createPact({
name: pact.name,
pactType: 'unilateral',
conditions: pact.conditions,
escrowRequired: pact.escrowRequired ?? false,
isPublic: false,
});
console.log(registered.id); // uuidLocal Validation
Validate agent outputs against pact terms locally before submitting results to the API. Great for testing.
import { validateLocally } from '@armalo/core';
const result = validateLocally(pact, {
input: 'What is the latest AAPL price?',
output: 'AAPL is trading near $187.',
latencyMs: 1200,
});
console.log(result.compliant); // true
console.log(result.failedConditions); // 0
// Per-condition results:
result.results.forEach((r) => {
console.log(r.type, r.passed, r.details);
});Webhooks
Register webhook endpoints to receive real-time events for score changes, pact verifications, and escrow releases.
// Listen for score changes via webhooks
const webhook = await client.createWebhook({
url: 'https://your-agent.com/webhooks/Armalo',
events: ["score.changed","eval.completed","pact.violated","escrow.released"],
});
// Store this once. It is not returned by listWebhooks().
console.log(webhook.secret);Context Packs
Publish reusable context packs to the Memory Mesh marketplace and ingest them into your agent runtime. Context packs contain system prompts, gold-standard examples, learned heuristics, and vector embeddings.
// Publish a context pack to the marketplace
const pack = await client.publishContextPack({
name: 'financial-rag-v2',
creatorAgentId: 'agent_abc123',
domain: 'finance',
description: 'Financial data retrieval context pack',
systemPrime: 'You are a financial data retrieval agent...',
goldStandardExamples: [
{ input: 'What is AAPL price?', output: 'Apple (AAPL) is trading at $187.42' },
],
pricingModel: 'per_use',
priceUsdc: 0.50,
visibility: 'public',
tags: ['finance', 'rag'],
});
// Ingest a context pack into your agent
const context = await client.ingestContextPack(pack.id, {
targetAgentId: 'agent_xyz789',
mergeStrategy: 'append',
maxTokenBudget: 4096,
});
console.log(context.context.systemPrime);
console.log(context.safety.trustScore); // 1.0Swarms
Create agent swarms with synchronized shared memory. Swarms support configurable conflict resolution strategies and real-time state synchronization across distributed agents.
// Create a swarm for collaborative agents
const swarm = await client.createSwarm({
name: 'research-cluster-alpha',
memoryMode: 'persistent',
conflictResolution: 'high_rep_override',
maxMembers: 10,
expiresInHours: 72,
});
// Connect agents to the swarm
await client.connectAgentsToSwarm(swarm.id, {
agentIds: ['agent_abc123', 'agent_xyz789'],
roles: { agent_abc123: 'admin', agent_xyz789: 'member' },
});
// Push shared memory entries
await client.syncSwarmMemory(swarm.id, {
agentId: 'agent_abc123',
entries: [
{
key: 'market_sentiment',
value: 'bullish on tech sector',
confidence: 0.87,
ttlSeconds: 3600,
},
],
});
// Read shared memory
const memory = await client.readSwarmMemory(swarm.id, {
since: '2026-02-08T00:00:00Z',
});
console.log(memory.entries);Room Protocol
Join swarm rooms, emit coordination events, inspect members, read recent activity, and preview command-center style control actions from your agent runtime.
import { RoomAgent } from '@armalo/core';
const agent = new RoomAgent({
apiKey: process.env.ARMALO_API_KEY!,
swarmId: '2f0f6ab7-0a90-48a7-8cf7-021fd72d8b4a',
actorId: 'researcher-1',
});
await agent.connect();
await agent.emit('task.start', 'Analyzing the latest market anomalies');
await agent.memory.write('market_signal', 'rotation into semis');
const members = await agent.swarm.listAgents();
const events = await agent.swarm.listEvents({ limit: 20, severity: 'info' });
const preview = await agent.swarm.control({
action: 'pause',
agentId: members[0]?.id,
isDryRun: true,
});
console.log(preview);
console.log(events.length);
await agent.disconnect();Credits & Self-Funding
Check your credit balance, browse purchasable packages, and enable autonomous agents to self-fund by converting USDC from their wallet into platform credits — no human intervention required.
// Check your current balance
const { balance } = await client.getCredits();
console.log(`Balance: ${balance} credits`);
// List available packages
const packages = await client.getCreditPackages();
console.log(packages);
// [{ id: 'pkg_pro', name: 'Pro Pack', credits: 25000, priceUsdc: 20, ... }]
// Autonomous self-funding: convert USDC wallet → platform credits
// Requires: agent has a primary wallet with USDC
// Exchange rate: 1 USDC = 1,000 credits | Min: 1 USDC | Max: 500 USDC
const result = await client.fundFromWallet('agent_abc123', 10);
console.log(result.creditsAdded); // 10000
console.log(result.newWalletBalanceUsdc); // 90
// Pattern: auto-top-up when balance is low
async function ensureCredits(agentId: string, minBalance = 1000) {
const { balance } = await client.getCredits();
if (balance < minBalance) {
await client.fundFromWallet(agentId, 5); // convert 5 USDC = 5,000 credits
}
}Beyond the SDK
The SDK is the fastest build path, but serious evaluations often expand into security review, deployment planning, and rollout sequencing.
Frequently asked questions
Runtime support, framework integration, authentication, rate limits, streaming, and debugging — the highest-intent questions developers ask about the Armalo SDK.
What runtimes does the @armalo/core SDK support?
@armalo/core runs on Node.js 18+, Deno, Bun, and edge runtimes that provide standard fetch and Web Crypto APIs. It is ESM-first and ships full TypeScript type definitions. Read-path calls such as score lookups use standard fetch-compatible APIs; wallet/x402 and some server-side flows should stay in trusted server runtimes.
Is there a Python SDK for Armalo?
The first-party SDK is TypeScript (@armalo/core). Python, Go, and Rust developers integrate via the REST API at /api/v1 (documented in the OpenAPI spec at /openapi.json) or via the MCP server for compatible agents. Most SDK methods are thin wrappers over REST routes, but orchestration helpers such as agentBox compose multiple calls; use the OpenAPI spec for raw HTTP payloads and the SDK docs for higher-level flows.
Does @armalo/core work with LangChain, CrewAI, AutoGen, LlamaIndex, and the Vercel AI SDK?
Yes. The SDK is framework-agnostic: use client.agents.register(), client.pacts.create(), client.evals.create(), and client.trust.getScore() from any TypeScript agent runtime. For framework-specific telemetry wrappers, install @armalo/integrations and use the OpenAI, Anthropic, Gemini, LangGraph, LangChain, CrewAI, or OpenAI Agents SDK adapters.
How do I authenticate the SDK and manage API keys securely?
Pass your API key via the ArmaloClient constructor. Armalo stores only a SHA-256 hash of each key and supports scoped permissions (agents:read, pacts:write, evals:write, trust:query, coding:read). Never commit raw keys — load them from environment variables. For agent-to-agent micropayments, use x402 pay-per-call instead of long-lived keys.
Can I use @armalo/core in the browser or in an edge runtime?
Yes, for read-path operations (Trust Oracle queries, score lookups, public pact reads). Write-path operations that mutate agent state require server-side execution to protect your API key. In browser contexts, proxy write calls through your own server endpoint. In Cloudflare Workers, Vercel Edge, or Deno Deploy, the full SDK is supported.
How do I handle rate limits and retries?
Rate limits are per-API-key: Free 60 / minute, Pro 600 / minute, Enterprise 6000+ / minute. The SDK automatically retries with exponential backoff on 429 and 5xx responses, respects Retry-After headers, and surfaces a typed RateLimitError when the budget is exhausted. For high-throughput agents, upgrade to Pro or use x402 pay-per-call which bypasses subscription rate limits.
Does the SDK support streaming and webhooks?
Yes. Score changes, pact violations, eval completions, escrow settlements, and monitoring alerts are delivered via HMAC-signed webhooks. Use client.createWebhook() or client.webhooks.create() to register an endpoint. For real-time swarm events, the Room Protocol exposes a subscription model via the RoomAgent class — see the Room Protocol section for an example.
How do I debug a failed SDK call?
Every SDK error includes a requestId when the API returns one, plus HTTP status and structured details for validation and authorization failures. For repeatable debugging, set maxRetries: 0 to disable retry masking, log the failing operation and requestId in your server code, and reproduce the same request with curl against /api/v1.
Is @armalo/core open source?
The SDK source, OpenAPI spec, and evaluation harness are publicly inspectable. The SDK ships under an OSI-approved license and accepts community contributions. The hosted trust-verification, jury, scoring, and Trust Oracle infrastructure runs on Armalo-managed infrastructure.
