Built for the engineers who get paged

Errand is infrastructure, so it behaves like it: explicit APIs, deterministic policies, full traces. Most teams publish their first agent surface the same afternoon.

quickstart

# 1. Install the CLI
npm i -g @errand/cli

# 2. Connect your stack
errand connect shopify   # or: stripe, square, custom

# 3. Publish your agent surface
errand publish
# -> catalog feed        https://agents.yourstore.com/catalog
# -> MCP server          https://agents.yourstore.com/mcp
# -> ACP checkout        https://agents.yourstore.com/acp/checkout
# -> llms.txt            https://yourstore.com/llms.txt

Boring by design

REST and JSON, idempotency keys, webhooks with signatures, sandbox mode. No SDK lock-in required.

Policy as code

Everything agents may do is declared in one reviewable file. Ship it through your normal PR flow.

Traceable end to end

Every order carries the originating query, the verified mandate, and the payment reference in one trace.

Full API reference and sandbox

Complete docs, a hosted sandbox with a fake store, and reference agents to test against ship with early access.
