Gomultiply

Multiply (gomultiply.com) is an AI-native paid media agency for B2B companies that combines proprietary self-learning advertising AI with human growth strategists. The platform plugs into a customer's sales calls and CRM data to learn why buyers actually convert, then uses 25+ specialized AI agents (customer insights, keyword, creative design, A/B testing, bidding, and attribution) to generate, launch, and continuously optimize hundreds of personalized ad experiments across Google and LinkedIn. Founded by Matt Jayson (formerly Google and Brex) and Ashish Warty (formerly SVP Engineering at HackerOne, Dropbox, and Airship), Multiply emerged from stealth with $9.5M led by Mayfield and reports 300-500% increases in sales meetings booked and pipeline generated for its B2B customers.

Gomultiply is profiled on the APIs.io network. Tagged areas include Company, Advertising, Marketing, Artificial Intelligence, and B2B.

Gomultiply’s developer surface includes pricing, signup flow, engineering blog, and 7 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
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
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)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

12 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
Developer Ergonomics scores 0.0 — up to +20.0 composite points
Operational Transparency scores 0.0 — up to +13.0 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/gomultiply/apis.yml: open an issue on github.com/api-evangelist/gomultiply to ask a question or point us at an artifact you publish.

  note: Full STEP 0b contract discovery run against www.gomultiply.com, getkalos.com (the legacy brand host, which 301s to
    gomultiply.com), app.getkalos.com and api.getkalos.com. No OpenAPI, Swagger, GraphQL, MCP, AsyncAPI, gRPC or A2A agent
    card exists on any host. The one real provider-published machine-readable artifact is /llms.txt, saved verbatim; the public
    pricing page yielded three real service tiers. Ownership note — docs.multiply.ai and github.com/multiply-ai belong to
    Multiply AI, a DIFFERENT (UK financial-advice) company, and were explicitly excluded.
x-coverage:
  state: none
  reason: no-developer-program
  detail: Multiply sells a managed AI paid-media agency engagement, not a developer product — its 17-URL sitemap contains
    no developer, docs, API, terms or status page, and its one publicly reachable backend, api.getkalos.com, answers its root
    with the plain-text string "yay response" while 404ing every OpenAPI, GraphQL, MCP and /.well-known/ path.
