Hilbert's AI

Hilbert's AI is an AI-native growth infrastructure platform for B2C companies, backed by a16z. It unifies fragmented product, marketing, and finance data into a single source of truth and layers agentic automation on top through four intelligence stages: Detect (anomalies, churn signals, and behavioral shifts), Reason (ML/deep-learning root-cause analysis and forecasting), Act (autonomous growth interventions such as churn plays and channel adjustments), and Optimize (continuous budget and strategy tuning). A natural-language interface lets growth, product, and finance teams collapse months-long decision cycles into minutes without writing code or navigating dashboards. Hilbert connects to existing data and paid-media stacks via prebuilt integrations (Meta, Google, Pinterest, Snapchat, Reddit, Google Analytics 4, Triple Whale, Klaviyo, Braze) and states SOC 2 on its own site. The product is delivered as a hosted application. There is no public developer program, but the application backend does publish a reachable Swagger UI and an OpenAPI 3.0.0 document at https://app-api.hilberts.ai/api-docs, which declares the platform's security schemes and core data models while shipping an empty paths object, so no operations are documented.

Hilbert’s AI publishes 1 API contract indexed on the APIs.io network: Hilbert’s Program API. Tagged areas include Company, Artificial Intelligence, Growth, Analytics, and Marketing.

Hilbert’s AI’s developer surface includes signup flow, engineering blog, and 11 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 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 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):

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
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

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. This rating is computed from the provider profile at artifacts.apis.io/hilberts-ai/apis.yml: open an issue on github.com/api-evangelist/hilberts-ai to ask a question or point us at an artifact you publish.

  description: The backend API of the Hilbert growth-infrastructure application. Its OpenAPI 3.0.0 document is published unauthenticated
    through a Swagger UI at https://app-api.hilberts.ai/api-docs. The document declares two security schemes (Auth0-issued
    bearer JWT and an x-api-key header for server-to-server calls) and eight component schemas covering users, organizations,
    metric calculation, and project goal tracking, but its paths object is empty, so no operations are documented. The production
    base URL is https://app-api.hilberts.ai/api/v1, observed as the configured API base and Auth0 audience in the application's
    own public JavaScript bundle; the spec's own servers[] block still carries the development placeholder http://localhost:3000/api/v1.

  note: 'Previously recorded as having no API surface. STEP 0b contract discovery found a real OpenAPI 3.0.0 served unauthenticated

    JavaScript bundle after every /.well-known/ and spec path on the marketing and app hosts missed. Ownership confirmed under
    STEP 0c: the spec self-identifies as "Hilbert''s Program" (hilbertsprogram.com), which is this company''s former identity
    and 301s to hilberts.ai. The document declares zero operations (paths is an empty object). A 1200-request per 60-second

    card, no SDKs, no webhooks and no published pricing.'
