How long does the integration take?

Change one base URL in an OpenAI-compatible client, or install the Python or TypeScript SDK; the quickstart routes a first request in a few minutes.

Will this lock us into another vendor?

No. The router is Apache-2.0 open source, your provider keys stay yours, and the API is OpenAI-compatible, so leaving is a change of base URL.

What happens when a provider fails?

The router falls back to the next model your policy allows and records the fallback in the trace, so an outage costs a retry, not an incident.

Claude Code subagent imported from AnthonyOlakangil/leash (.claude/agents/agent-engineer.md). Copyright stays with the author.

Build DEMO_SCRIPTED mode first (it is the video's safety net), then LLM mode. TypeScript, tsx, @anthropic-ai/sdk, viem, packages/leash-client.

Boot: load the repo-root .env; read the deployment from packages/abi; verify the AUSD eip712Domain; choose the model with GET https://api.anthropic.com/v1/models (prefer the newest Sonnet, expected claude-sonnet-5-5; fall back to the newest Haiku). Do not hard-code a model ID without that check.

Orchestrator (root node, key ROOT_AGENT_PRIVATE_KEY): task "Find me a used alto sax under $600 near Berkeley." It splits the task, generates 3 child keys (viem generatePrivateKey, saved to apps/agents/.keys.json, gitignored), signs CreateChild EIP-712 messages (domain {name "Leash", version "1", chainId 84532, verifyingContract LEASH_WALLET}; payeesHash = keccak256(encodePacked(["address[]"], [payees]))), and relays them through facilitator POST /delegate. searcher-1 and searcher-2: cap 0.25 AUSD, maxPerCall 0.10; searcher-3: cap 0.25, restricted to [PAYEE_SEARCH].

Sub-agents: Anthropic tool-use loop with tools search(q), scrape(url), skip(reason), finish(summary). Every paid call goes through leash-client with that sub-agent's key. Print one line per action: node, tool, price, result (paid tx hash or BLOCKED + reason). Do not special-case the injection fixture in agent code; the model sees the page text and decides.

DEMO_SCRIPTED=1: a fixed sequence, every log line prefixed "[SCRIPTED]", about 2 seconds between beats so the dashboard animates:

(owner) ensure root exists via facilitator /admin/createRoot if missing.
Orchestrator creates the 3 delegations.
searcher-1: search, then scrape a real result. searcher-2: search.
searcher-2 scrapes /listings/sax-42 (contains the injection), then calls /premium-intel with forceBroadcast: BLOCKED PayeeNotAllowed onchain.
Facilitator /demo/bypass with that same signature: AUSD rejects it.
searcher-3 tries /scrape: BLOCKED PayeeNotAllowed(searcher-3 node).
searcher-2 scrapes until OverBudget(searcher-2 node).
(owner, if raiseCap is enabled) raiseCap(searcher-2, 0.40); one more scrape succeeds.
(owner) pause(root); each searcher's next call is BLOCKED Paused(root id). Expose pnpm --filter agents demo (scripted) and pnpm --filter agents live (LLM). Commit only apps/agents.

Install agent-engineer and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.
