Archil

Archil is the cloud filesystem for AI. It turns an existing object-storage bucket (Amazon S3, Google Cloud Storage, Cloudflare R2, Azure Blob, MinIO, Wasabi, Backblaze B2, DigitalOcean Spaces) into an unlimited, POSIX-compatible local disk that thousands of machines can mount at once — live, in place, and faster than local disk. A single multi-tenant "disk" caches active data in a high-speed layer, supports copy-on-write branches and checkpoints for isolated agent and CI fan-out, and can run serverless bash and parallel grep directly against the data with no separate sandbox. Archil exposes a REST Control Plane API for managing disks, disk users, API tokens, and serverless execution, plus first-party TypeScript and Python SDKs, a `disk` CLI, a Linux `archil` mount CLI, a Kubernetes CSI driver, a Terraform provider, and an S3-compatible HTTP API. Founded 2024, backed by Felicis, Y Combinator, General Catalyst, Peak XV, and Standard Capital. Added to the API Evangelist network from the Felicis portfolio and enriched by the pipeline.

Archil publishes 4 API contracts indexed on the APIs.io network, including API Tokens API, Disk Users API, Disks API, and 1 more. Tagged areas include Company, Cloud Storage, Filesystem, Object Storage, and Artificial Intelligence.

The Archil catalog on APIs.io includes 1 Spectral governance ruleset.

Archil’s developer surface includes documentation, API reference, getting-started guide, signup flow, support, engineering blog, pricing, and 25 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
