Marin Software

Marin Software is a performance marketing and digital advertising management platform used by e-commerce brands, agencies, and enterprise marketers to plan, automate, and optimize paid media at scale across paid search, paid social, retail media, and app advertising channels. Its product line includes MarinOne (campaign management and automation), Marin Connect (marketing data collection and unification), Marin Ascend (cross-channel optimization), Marin for Agencies, and managed services. Marin publishes a POST-only REST write API — the Marin API, at https://api.marinsoftware.com/open-api version 0.1 — that pushes campaigns, groups, keywords, ads and strategies into the platform using HTTP Basic auth, documented only in the help center, plus a Marin Social API whose reference link no longer resolves. There is no OpenAPI, no SDK, no changelog and no status page, and the developer documentation portal has been decommissioned. Marin Software has been acquired by Zax Capital, which the company announces on its own homepage.

Marin Software is listed with 1 API on the APIs.io network. Tagged areas include Company, MarTech, Advertising, Marketing, and Performance Marketing.

Marin Software’s developer surface includes pricing, engineering blog, signup flow, documentation, API reference, support, authentication, and 16 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
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
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
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link

10 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 0.0 — up to +25.0 composite points
Operational Transparency scores 0.0 — up to +13.0 composite points
Developer Ergonomics scores 35.7 — up to +12.9 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/marin-software/apis.yml: open an issue on github.com/api-evangelist/marin-software to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

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.

Amazon Seller Ecosystem (Selling Partner Appstore, Amazon Ads partners)	builds-on	19.7 (thin)	-	-

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.
