Agents hand off work. Keyline carries it.

1Delegation
The orchestrator splits the task and assigns each part to an agent.
2Parallel execution
Research and Code start together. Neither waits for the other.
3Handoff
Research passes its findings to the Analyst, which starts with that context.
4Tool activation
Each agent calls what it needs: search, a data source, a sandbox.
5Completion
Outputs converge into one result. Every hop on the way is recorded.

Submit a task. Watch it route.

Keyline plans the task, picks the tools and models it needs, runs the independent steps in parallel and records every call.

One key for agents, models & tools.

Route every call.
Models, tools and agents sit behind one execution layer.
Observe every execution.
Each call is traced with its parent, latency and cost.
Pay only for what executes.
Candidates the router considers and skips cost nothing.

How the platform is put together

Draft API. Not available yet; names may change before release.

// One key. The router decides what each step calls.
const run = await keyline.executions.create({
  input: 'Find trending Robinhood Chain tokens and summarize activity.',
  allow: ['models', 'tools', 'apis'],
  budget: { maxCostUsd: 0.05 },
});

run.output;  // the result
run.usage;   // { calls, latencyMs, costUsd }
run.trace;   // every call, with its parent

Where Keyline is today

Keyline is early. This is what exists and what does not, kept current as things ship.
