Archastro

ArchAstro is a Seattle-area startup building a runtime for cross-company AI agents: privacy-aware agents deployed on both sides of a business relationship that collaborate on integrations, migrations, upgrades, onboarding, testing, and bug fixes, with shared test visibility and human approval gates. The ArchAstro Platform API is an agent-first developer control plane covering users, teams, agents, routines, threads, messages, knowledge, tools, installations, workflows, sandboxes, integrations, and inbound webhooks, with first-party TypeScript and Python SDKs and a CLI. Founded in 2026 by engineering veterans from Microsoft, Stripe, Statsig, and Meta; backed by a $6.2M pre-seed.

Archastro publishes 10 APIs on the APIs.io network, including Activity Feed API, Agents API, auth API, and 7 more. Tagged areas include Company, AI Agents, Agentic, Developer Platform, and Automation.

The Archastro catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Archastro’s developer surface includes documentation, API reference, getting-started guide, authentication, CLI, sandbox, changelog, and 21 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/archastro: open an issue to ask a question, or submit a pull request to add artifacts.
