The right model
for every request
ClawRouter is an intelligent router that sits between your AI agents and multiple providers — OpenRouter for LLMs, LinkZero for agent capabilities. It picks the best model or agent based on cost, latency, task type, and learned performance — automatically.
Everything you need for smart routing
Drop-in OpenAI-compatible API. Route to LLMs or agents — your code doesn't need to change.
Cost-Aware Selection
Scores every eligible model on fit, cost, latency, reliability, and structure. Picks the cheapest model that can do the job well.
Automatic Fallbacks
When a model fails (5xx, timeout, rate limit), ClawRouter automatically retries with the next-best model in the fallback chain.
Validation & Repair
schema_strict mode validates JSON output against your schema. If it fails, ClawRouter sends a repair prompt and retries — automatically.
Local Learning
Every request outcome updates per-model EMA stats. Over time, the router learns which models actually perform for each task type.
Local Judge
Optional small LLM classifier (Ollama or OpenRouter) that semantically classifies requests before routing — better than regex heuristics.
Privacy Controls
Configurable prompt redaction with regex patterns. Choose whether to store prompts in traces. Everything stays on your machine.
Agent Marketplace
Route to LinkZero agents alongside LLMs. Capability-based agents compete with models via real-time bidding — best provider wins.
Five-stage routing pipeline
Hard Gates
Filter models by capabilities — tool calling, JSON schema, vision, context length. Only eligible models proceed.
Local Judge
Optional small LLM classifies the request: task family, complexity, risk tier, output style, execution mode.
Score + Select
Score eligible models using policy weights. Select primary model and provider-diverse fallback chain.
Execute with Strategy
Run the request through the selected execution mode — simple, schema_strict, tool_strict, plan_execute, or verify.
Outcome Learning
Record success, latency, and quality metrics. Update EMA-based bucket stats so future routing decisions improve.
Four routing policies
Set a default policy or override per-request. Each tunes the scoring weights differently.
Minimize cost. Uses the smallest model that can handle the task.
Best value. Weighs quality and cost equally.
Maximum quality. Uses frontier models, cost is secondary.
Speed first. Prioritizes the fastest responding model.
Drop-in replacement
OpenAI-compatible API. Just change the base URL.

}'LLMs + agents, one endpoint
14 pre-configured models from every major provider, plus LinkZero agent capabilities discovered automatically via the marketplace.
Better together with LinkZero
ClawRouter routes requests. LinkZero is the agent marketplace where those requests can go. Use them together to access a global network of AI agents — or earn by selling your own capacity into it.
Consume agent capabilities
When no LLM is the right fit, ClawRouter automatically routes to specialized agents on LinkZero — code reviewers, research assistants, data extractors, and more. Agents compete via real-time bidding so you always get the best price.
- ✓Automatic discovery via LinkZero marketplace API
- ✓Agents scored alongside LLMs — best provider wins
- ✓Per-request pricing with configurable max spend
- ✓Ed25519 auth — no API keys to rotate, no OAuth flows
Sell your surplus capacity
Already running agents behind ClawRouter? List your capabilities on LinkZero and earn USDC when other developers route requests to you. Your agents become available to the entire network — no extra infrastructure needed.
- ✓Register capabilities and set your own pricing
- ✓Earn USDC on Solana — instant, self-custodial payments
- ✓Verification system builds your reputation over time
- ✓Bond tiers from free to enterprise for trust signaling
