Titan Swap API - Claude Skill

Installation

Claude Code plugin (recommended)

This repo is a Claude Code plugin marketplace. Install directly from inside Claude Code — no Node, no npm:

/plugin marketplace add Titan-Pathfinder/titan-api-claude-skills
/plugin install titan-swap-api@titan-exchange

Updates and uninstalls are managed natively via /plugin. Then type /titan-swap-api in Claude Code to invoke the skill.

npx (alternative)

If you'd rather install via npm:

For current project:

npx @titanexchange/titan-api-skill

For all projects (global):

npx @titanexchange/titan-api-skill --global

Overwrite existing install:

npx @titanexchange/titan-api-skill --force

Manual install (curl)

If you prefer not to use npx or the plugin system:

What This Skill Provides

• Protocol-aware code generation — Generates TypeScript with correct MessagePack encoding, BigInt amounts, and bs58-decoded token mints matching the Titan WebSocket API spec.
• SDK and raw WebSocket support — Covers both SDK-based and direct WebSocket integration depending on developer needs.
• Parameter structure enforcement — Places fields like slippageBps, intervalMs, and num_quotes in their correct nested objects matching the expected request schema.
• Runnable examples included — Ships with working TypeScript examples that can be executed directly after setting up environment config.

Quick Example

Ask Claude Code:

"Help me stream USDC to SOL quotes using Titan API"

Claude will guide you through:

import { V1Client } from "@titanexchange/sdk-ts";
import bs58 from "bs58";

const client = await V1Client.connect(`${WS_URL}?auth=${AUTH_TOKEN}`);

const { stream } = await client.newSwapQuoteStream({
  swap: {
    inputMint: bs58.decode("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"),
    outputMint: bs58.decode("So11111111111111111111111111111111111111112"),
    amount: BigInt(100_000_000), // 100 USDC - must be BigInt!
  },
  transaction: {
    userPublicKey: bs58.decode(USER_PUBLIC_KEY),
  },
});

for await (const quotes of stream) {
  console.log(quotes);
}

Runnable Examples

The /examples directory contains working TypeScript examples:

cd examples
npm install
cp .env.example .env
# Edit .env with your credentials

npm run stream-sdk   # SDK streaming
npm run stream-raw   # Raw WebSocket
npm run proxy        # Backend proxy

Key Things to Know

| Topic | Details | |-------|---------| | Protocol | WebSocket + MessagePack (not JSON) | | Amount | Must be BigInt, not number | | Token mints | Must be Uint8Array via bs58.decode() | | Parameters | slippageBps in swap, intervalMs in update |

Required Credentials

| Variable | Description | |----------|-------------| | WS_URL | Titan WebSocket endpoint | | AUTH_TOKEN | API authentication token |
