Tofu

Tofu (tofuhq.com) is an agentic go-to-market platform for B2B revenue teams, running always-on marketing and sales campaigns across email, LinkedIn and landing pages inside a team's existing GTM stack. Three agents — Research, Create and Launch — scale 1:1 ABM to hundreds of accounts, covering outbound prospecting, lead nurture, event follow-up, sales acceleration, stalled-deal re-engagement and customer expansion, and integrating with Salesforce, HubSpot, Marketo, Outreach and Salesloft. Tofu also ships a public, self-serve developer product: the Enrich API (api.enrich.tofuhq.com), a credit-metered company and people data API covering firmographics, funding, headcount, hiring, web traffic, competitors and verified business emails. It is deliberately agent-first — the documented interface is a first-party CLI (@tofuhq/enrich) driven by a published Agent Skill rather than an SDK, and its two schema endpoints answer unauthenticated. Backed by Index Ventures; Tofu states it is SOC 2 certified.

Tofu is listed with 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Marketing, Go-To-Market, and Sales.

Tofu’s developer surface includes documentation, engineering blog, signup flow, CLI, authentication, changelog, and 22 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.

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 47.6 — up to +10.5 composite points
Contract Governance scores 18.2 — up to +9.8 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/tofu/apis.yml: open an issue on github.com/api-evangelist/tofu 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.

Market	Position	Depth	Registered MCP server	Declares compatibility
Agent Skills (SKILL.md packages)	standard	34.5 (thin)	-	2

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 2

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.

  description: Credit-metered company and people data enrichment. Two entities — company (keyed on domain or LinkedIn URL)
    and person (keyed on LinkedIn profile URL or business email) — with a structured filter grammar for search and group/dotted-path
    field selection for enrichment. Company records cover firmographics, taxonomy, headcount and growth, funding and investors,
    hiring, web traffic, SEO, Glassdoor/G2 ratings, news, decision-makers and competitors; person records cover employment
    history, education, skills, GitHub, social and verified business email. Credits are charged per record returned, with
    no charge when nothing matches. Authentication is a bearer API key prefixed enr_, provisioned by emailed one-time code
    through the CLI. No OpenAPI is published, but GET /v1/schema/company and GET /v1/schema/person return the complete filter
    and field vocabulary unauthenticated.
