Hi I can build complete API client libraries for Hyperliquid and Lighter covering every documented REST + WebSocket endpoint, including trading, account, and market data. The main technical risk is incorrect auth/signature handling and rate-limit behavior, which causes silent order failures, duplicate submissions, or inconsistent portfolio snapshots. I solve this with a modular client (separate Trading/Account/Market modules), strict request signing/session management, idempotency-safe order helpers, and unified pagination/mapping. WebSocket streams will be wrapped with reconnect/backoff, heartbeat handling, and event normalization so real-time books/trades/positions stay reliable. Error handling includes typed exceptions, retry policies for transient failures, and clear propagation for non-retryable exchange errors. The deliverable includes full method-level docs, strongly-typed response models, and example scripts for place/modify/cancel, batch orders, and portfolio snapshots. Code will be clean, fully transparent, and easy to extend when new endpoints appear. Thanks, Hercules

Hello, integrations like this usually go sideways when people “cover the main endpoints” but miss edge methods, WS streams, auth quirks, and rate-limit behavior, so I’ll build complete, documented clients for both Hyperliquid and Lighter that match their API docs end-to-end. I’ll implement every documented REST endpoint plus WebSocket/streaming where available, including trading (buy/sell, batch, modify if supported, cancel one/all), portfolio snapshots and real-time views (balances, margin, positions, PnL, history), and market/system data (metadata, order books, trades, funding/fees, status, limits). Code will be modular per domain, with clean request wrappers, retries/backoff, idempotency where applicable, and strict input/output models so it’s hard to misuse. Preferred language: Python (httpx + asyncio + pydantic + websockets) with examples and docs, but I can do TypeScript if your stack is JS-first. I’ve built multiple crypto trading API clients and bots before, so I’m comfortable with signing, latency, and production-safe error handling. Timeline: 4–5 days for full coverage across both platforms (depends on doc breadth). Cost: $400 fixed for both clients + examples + docs. Warm regards, Yulius Mayoru

@dicongz

I can build a complete, production-ready API client for both Hyperliquid and Lighter by implementing every officially documented REST and WebSocket endpoint, covering trading, account data, market data, and system status without omissions. The integration will be modular, fully documented, rate-limit aware, and designed for reliability with proper retries and error handling. I’ve worked extensively with crypto trading APIs (centralized and on-chain), including order lifecycle management, real-time feeds, and PnL/account reconciliation. I’d recommend TypeScript or Python for clarity and maintainability, and I can deliver clean example usage for all core actions. Best regards, Dicong

@ayesha86664

Hi there! I understand the challenge: you need full-featured API integrations for Hyperliquid and Lighter, exposing every endpoint reliably while respecting rate limits and handling real-time updates. Missing even one key feature or poorly handling errors could break trading operations or portfolio monitoring. My approach: I’ll review both API docs thoroughly, implement all available endpoints, and include order management, portfolio snapshots, market feeds, and trade history. I’ll build a clean, modular client with full WebSocket support where available, robust error handling, and clear examples for trading, batch operations, and portfolio queries. Full documentation and transparent source code will be delivered so your team can maintain or extend it easily. Do you have a preferred programming language for the integration, or should I recommend one optimized for speed and reliability? Start /Open chat now.

@codefusion53

Hi, I can develop full API integrations for Hyperliquid and Lighter, covering all documented endpoints for trading, order management, portfolio monitoring, and market data. I will implement real-time streaming where supported, with proper error handling, authentication, and rate-limit compliance. The solution will be modular, clean, and fully documented, with example scripts for placing trades, cancelling orders, and retrieving portfolio snapshots. Source code will be delivered without obfuscation, giving you full transparency and ownership. My experience with cryptocurrency APIs, Python and JavaScript development, and building reliable trading tools ensures a robust integration that meets all your requirements efficiently and accurately. Best, Justin

@venplura

Hi there! Are you looking for the WebSocket real-time data streams for both platforms to be integrated alongside the REST API or just for selected endpoints? Regardless, this is definitely something that I feel confident delivering on, given my past experience. I would love to discuss your project further! Looking forward hearing from you. Kind Regards, Corné

@kareemmaize

Hi, there. The hardest part here isn’t wiring endpoints, it’s guaranteeing full coverage and consistent behavior across orders, positions, and real-time streams without drifting from the official specs. I’ve seen crypto integrations fail when batch orders, cancels, or WebSocket updates aren’t reconciled correctly with REST snapshots, leading to stale exposure or phantom orders. I mitigate this by mapping every documented endpoint first, implementing strict models around order lifecycle, and validating WebSocket feeds against REST state before exposing them to users. I’d sequence this as API audit, core REST client, WebSocket integration where supported, then examples, docs, and edge-case testing around rate limits and auth. You’ll receive a complete, transparent client covering all documented endpoints, with examples and clear usage instructions. Do you want this delivered as a single unified client or two separate libraries?

@Sturneraiseosa

Hi, how are you? I’ve built production-grade crypto trading API clients (REST + WebSockets) with full order management, portfolio/PnL, and market-data streaming, including robust auth, rate-limit handling, retries, and clean SDK-style structure. I understand you don’t want a partial wrapper—you need complete, endpoint-by-endpoint coverage of Hyperliquid and Lighter’s official APIs with transparent code ownership, examples, and documentation so you can trade, monitor, and extend safely. I can deliver a modular Python (or TypeScript) client with thorough method docs and setup instructions. Let’s discuss your project in detail. Thank you. Edgova IT Solutions
