The AI infrastructure layer
One API, Every Model
Swap one base URL. Instantly route to GPT, Claude, Gemini, and hundreds more — with built-in fallback, cost control, and machine-readable errors that let your agents self-heal.
OpenAI-compatible
Live model catalog — query what's available at runtime, no hardcoded lists
300+ models
Structured recovery — retry windows and ranked fallbacks in every error payload
Pay per token
Scalable by design — one integration today, a coordinated agent fleet tomorrow
Runtime trace
01 / 03Model discovery
3 live options ranked
Failure recovery
retry hint returned
Agent orchestration
Single call to multi-agent fleet
Agent-First Design
Other APIs throw errors. LemonData returns a next step.
The real differentiator isn't how many models you can access — it's whether your agent can recover autonomously when a call fails.
Traditional API
- 1400 {"error":{"message":"Model not found"}}
- 2Agent crawls docs for the correct identifier
- 3Agent retries with a guessed name
- 4Blind retries burn tokens and time
LemonData
- 1400 {"code":"model_not_found","did_you_mean":"gpt-4o"}
- 2Agent parses the structured hint
- 3Agent retries with the correct model
- 4Workflow resumes — zero human intervention
Three primitives that keep agents autonomous
Machine-readable error payloads
Every error carries did_you_mean, retry_after, and ranked alternatives — structured for programmatic consumption, not just human reading.
Runtime model discovery
/v1/models and llms.txt expose a live, queryable catalog — your agent always knows what's available without scraping docs.
Optimal endpoint routing
Responses include the recommended native endpoint for each model, so your agent picks the most efficient path automatically.
Platform
One base URL. The entire AI stack.
Explore models, compare them head-to-head, read the architecture guide, or launch a persistent agent — all under one roof.
Model directory
Capabilities, pricing, and availability for every model — searchable and always current.

LemonClaw
A persistent agent runtime — deploy in seconds, scale to a coordinated multi-agent team when the workload demands it.
Meet LemonClaw
LemonClaw
Your AI workforce, managed
LemonClaw gives you a production-grade agent runtime — one that remembers context, plans ahead, and scales into a specialized team as complexity grows.
Agent Runtime
Persistent & autonomous
A single long-running agent that researches, plans, executes, and retains memory across sessions — always available, continuously improving.
Team Orchestration
Multi-agent coordination
Assign specialized roles — research, execution, review — and let LemonClaw coordinate them as one cohesive unit.
Grow from solo to squad
Start with a single agent on the critical path. As tasks diversify, spin up specialists and let the runtime handle handoffs.
Perception
Ingests files, web content, IM threads, and knowledge bases — no manual piping required.
Execution
Invokes tools, writes to APIs, dispatches messages — carries out decisions on your behalf.
Memory
Layered recall: session context, long-term facts, and user-supplied documents — all persistent across restarts.
Planning
Decomposes goals into steps, pauses for approval when needed, and tracks progress over extended timelines.
Self-Repair
Catches failures, diagnoses root causes, and reroutes — before you even notice something went wrong.
Governance
High-risk operations require explicit approval. Every action is logged, auditable, and interruptible in real time.
Pricing

FAQ
Frequently Asked Questions
What is LemonData?
LemonData is a unified AI gateway. One API endpoint gives you access to 300+ models from OpenAI, Anthropic, Google, and other leading providers — with agent-friendly error handling, built-in fallback routing, and per-model cost transparency.
How does pricing work?
Pure pay-as-you-go. Add credits to your balance and pay per token consumed. Most models are priced 30–70% below official rates, and every cost is visible in the dashboard before you spend.
Is LemonData compatible with OpenAI SDK?
Fully compatible. Point your existing OpenAI SDK at our base URL, swap in your LemonData API key, and every model — including Claude, Gemini, and DeepSeek — works through the same interface.
Is there a free trial?
Every new account receives complimentary credits. Connect the API, run real requests, and evaluate the platform before adding funds.
