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, Developer Platform, Automation, and Integration.

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.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
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.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
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.
