Valid

Valid is an AI-native advertising agency that grows consumer companies through an end-to-end performance marketing offering, combining AI-generated performance creative (20+ ads per month, moving from concept to launch in about three days), brand-specific AI-influencers with organic followings, and managed media buying across Meta, TikTok, Google, Snap, and AppLovin. Every managed client also receives the "Chat With Your Ads" MCP server — a live, first-party Model Context Protocol endpoint at mcp.valid.co that lets an agent query the whole ad account in plain English. That MCP surface is customer-gated rather than public: it is protected by an OAuth 2.1 authorization code flow with PKCE and RFC 7591 dynamic client registration, and it correctly serves the full RFC 9728 / RFC 8414 discovery chain, but Valid publishes no developer portal, no documentation, no OpenAPI, and no tool catalog, so the capability surface is invisible without a client account. Valid is backed by Canaan Partners and based in San Francisco, California.

Valid is listed with 1 API on the APIs.io network. Tagged areas include Company, Advertising, Marketing, Artificial Intelligence, and Creative.

Valid’s developer surface includes support and 14 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

7 more unmet checks in the Agent Readiness table above.

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.

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.

Market	Position	Depth	Registered MCP server	Declares compatibility
TAG-Certified Ad Fraud and Brand Safety	undeclared	-	1	-

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 implemented 3

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.
