SIMA Agent SDK

TypeScript client for SIMA's production agent protection purchase API.

Package: @sima-prime/agent-sdk
OpenAPI: https://sima-prime.com/openapi.json
API base: https://api.sima-prime.com

Core principle:

For bots and AI agents, the API is the product.

Install

npm install @sima-prime/agent-sdk

pnpm add @sima-prime/agent-sdk
yarn add @sima-prime/agent-sdk

Production purchase flow

Aligned to OpenAPI x-sima-agent-protection-purchase-flow-path:

POST /agent/wallet/nonce
POST /agent/wallet/verify
POST /agent/protection/offer
POST /agent/protection/purchase
GET  /agent/protection/certificates/{id}/payment-intent
     → caller sends SOL on-chain (outside SDK)
POST /agent/protection/certificates/{id}/confirm-payment
GET  /agent/protection/certificates/{id}

All commercial amounts are asset-denominated (contract asset / SOL). There are no USD commercial fields.

Quickstart

import { SimaAgentClient } from "@sima-prime/agent-sdk";

const client = new SimaAgentClient();

const nonce = await client.requestWalletNonce("YOUR_WALLET_ADDRESS");
// Sign nonce.message with your wallet outside this SDK.
const auth = await client.verifyWalletSignature({
  chain: "SOLANA",
  walletAddress: "YOUR_WALLET_ADDRESS",
  message: nonce.message,
  signature: "YOUR_SIGNATURE",
});
client.setAccessToken(auth.accessToken);

const offer = await client.getProtectionOffer({
  chain: "SOLANA",
  walletAddress: "YOUR_WALLET_ADDRESS",
  assetAddress: "YOUR_ASSET_ADDRESS",
  assetSymbol: "EXAMPLE",
  assetType: "TOKEN",
  protectedAmount: "1000",
});

const purchase = await client.purchaseProtection({
  ...offer,
  chain: "SOLANA",
  walletAddress: "YOUR_WALLET_ADDRESS",
  assetAddress: "YOUR_ASSET_ADDRESS",
  assetType: "TOKEN",
  protectedAmount: offer.protectedAmount,
  offerId: offer.offerId,
  protectionDecision: "PURCHASE_PROTECTION",
});

if (purchase.protectionDecision !== "PURCHASE_PROTECTION") {
  throw new Error("Protection declined");
}

const intent = await client.getPurchasePaymentIntent(purchase.certificateId);
// Send intent.amountDue SOL to intent.destinationTreasuryWalletAddress
// with your wallet / bot runtime. Keep the on-chain signature.

const active = await client.confirmPurchasePayment(purchase.certificateId, {
  paymentReference: intent.paymentReference,
  transactionSignature: "YOUR_ON_CHAIN_SIGNATURE",
});

console.log(active.certificateNumber, active.certificateStatus);

Client methods

| Method | Endpoint | | --- | --- | | requestWalletNonce | POST /agent/wallet/nonce | | verifyWalletSignature | POST /agent/wallet/verify | | getProtectionOffer | POST /agent/protection/offer | | purchaseProtection | POST /agent/protection/purchase | | getPurchasePaymentIntent | GET /agent/protection/certificates/{id}/payment-intent | | confirmPurchasePayment | POST /agent/protection/certificates/{id}/confirm-payment | | getProtectionCertificate | GET /agent/protection/certificates/{id} |

SIMA V1 economics

Premium             = 5% of protected amount
Coverage            = 50% of protected amount
Deductible          = 10% of protected amount
Maximum Net Payment = 40% of protected amount

Official timing (BM-001)

| Concept | Duration | | --- | --- | | Quote Validity | 30 seconds | | Payment Window | 30 seconds after acceptance | | Protection Window | 5 minutes after premium payment | | Certificate Lifetime | 24 hours from issuance | | Claim Window | 24 hours from issuance | | Historical Record | Permanent |

Safety boundaries

The SDK does not:

• store private keys or seed phrases
• sign wallet messages
• execute blockchain transfers or collect premium on-chain
• approve claims or authorize payouts
• change SIMA V1 economics

A certificate is purchased coverage and the right to submit a claim for investigation. Claim decisions and treasury payout remain separate steps.

MCP

Read-only discovery MCP (does not call the API):

npx @sima-prime/mcp-server

sima_get_quote_flow documents getProtectionOffer with protectedAmount (asset-denominated).

Open source boundary

This repository is the public SDK, examples, and discovery metadata.

Private core systems (treasury ops, claims investigation internals, production deployment) remain in the private SIMA monorepo.
