4Info

4INFO, Inc. was a San Mateo (originally Palo Alto) California advertising-technology company founded in 2004 by Pankaj Shah and Zaw Thet. It began as an SMS content and alerting service — Nielsen called it the largest business-to-consumer SMS content provider in North America in 2008 — then pivoted in 2010 into mobile display advertising with the AdHaven platform, a mobile ad server, audience data-management and analytics stack sold to publishers, aggregators and national advertisers. Its later product was an identity graph: patented technology ("Systems and methods for statistically associating mobile devices to households") that statistically resolved mobile devices, set-top boxes and connected TVs back to a single household so brands could target and measure across screens. mBlox bought the legacy SMS business in 2015, and Cadent acquired the remaining company in January 2020, folding the identity and cross-screen targeting technology into Cadent's advanced-TV platform. 4INFO no longer operates as an independent company: 4info.com is retained for email only and publishes no A or AAAA record, so there is no website, developer portal, API reference or machine-readable contract of any kind on any 4Info host, live or archived.

4Info is profiled on the APIs.io network. Tagged areas include Company, Advertising, AdTech, Mobile Advertising, and Advanced TV.

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

13 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
Access Clarity scores 0.0 — up to +20.0 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/4info/apis.yml: open an issue on github.com/api-evangelist/4info 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.

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.

x-acquisition-note: Cadent announced the acquisition of 4INFO on 2 January 2020; all 30 4INFO employees joined Cadent. The
  GitHub organization github.com/4info is still named "4info Organization (Cadent)". Cadent's own surface (cadent.com) is
  a separate company record and is deliberately NOT wired here as a 4Info property.
x-domain-status: mail-only
x-domain-note: 4info.com is delegated to AWS Route 53 and carries live Proofpoint MX, SPF and DMARC records, but publishes
  NO A or AAAA record on the apex or on www — every HTTP request fails at DNS resolution (curl exit 6, status 000). The last
  Internet Archive capture of the site is 2023-02-02 and the following capture, 2023-05-28, was a 404. There is no host to
  wire as a Website pointer. The forgeglobal.com/4info_stock/ URL this record was harvested from is a third-party secondary-market
  venue listing, not 4Info's web presence, so it is recorded as x-harvest-source-url rather than as a Website pointer (roadmap#56).
