Dagger is an open-source programmable CI/CD engine that runs pipelines in containers using a unified, introspectable GraphQL API. Pipelines are written as code in the developer's preferred language (Go, Python, TypeScript, PHP, Java, .NET, Elixir, or Rust) using Dagger SDKs and packaged as Dagger Modules that can be published to the Daggerverse module index. The Dagger Engine exposes Container, Directory, File, Secret, and CacheVolume as first-class GraphQL types backed by a content-addressed store, enabling deterministic builds and aggressive caching. Dagger Cloud provides the hosted control plane for pipeline traces, checks, and module observability. Dagger does not expose a public REST API; clients connect to a per-session Dagger Engine GraphQL endpoint and the optional Dagger Cloud Web UI.
Dagger publishes 5 API contracts indexed on the APIs.io network, including Graph QL API, and 4 more. Tagged areas include Build Automation, BuildKit, CI/CD, Containers, and DAG.
The Dagger catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Dagger’s developer surface includes authentication, documentation, getting-started guide, engineering blog, pricing, signup flow, YouTube channel, and 43 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.
Open Source Surface applies to this provider. This product is open source and we
read its repository directly, so Open Source Surface carries
10 points of the composite. It is scored from what the repository actually
publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the
provider rather than inferred from our own catalog pointers.
This facet adds; nothing was taken away to make room for it. An open-source project is not excused from
the commercial facets, because exemption would strip it of the points it does earn.
If we have the wrong repository, or this product is not open source, say so on your
provider repo and we
will drop the facet rather than have you publish against it.
Create-or-Update Ergonomics does not apply to this provider. The published contracts declare
no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's
denominator entirely — not scored zero. A reference or data API is not deficient for being unable to
upsert.
The six quality facets above are damped to 75 points between them,
because both conditional facets apply and carry
25 points together. 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):
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Delegated User Identity+6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Typed Event Surface+6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility+6 pts — a reversal operation in the contract, graded up when a window is documented too
5 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
