11x

11x builds autonomous AI "digital workers" for revenue teams — Alice, an outbound AI SDR that prospects, researches, and runs multi-channel email and LinkedIn outreach against a 400M+ B2B contact database, and Julian, an inbound AI phone, chat, and SMS rep that qualifies leads and books meetings in real time. The company markets a single unified platform API across both workers for triggering outbound, inbound, and meeting booking from external systems, plus webhooks and native bi-directional Salesforce, HubSpot, and Zoho CRM sync brokered over OAuth via Ampersand. Founded in 2023 with offices in San Francisco and London, 11x has raised roughly $75M across Seed, Series A (Benchmark Capital) and Series B (Andreessen Horowitz), with participation from HubSpot Ventures, Abstract Ventures, and 20VC. The platform API reference and any machine-readable specification are not published publicly — api.11x.ai answers anonymous requests with HTTP 403 and the marketing API page routes to a sales demo rather than a developer reference.

11x is listed with 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Agents, Sales, and Sales Automation.

11x’s developer surface includes documentation, engineering blog, support, signup flow, pricing, changelog, authentication, and 24 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the AI & Biometrics 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
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)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
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

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/11x/apis.yml: open an issue on github.com/api-evangelist/11x to ask a question or point us at an artifact you publish.

  description: A single API surface across Alice (outbound) and Julian (inbound/voice) that triggers outbound campaigns, inbound
    qualification, and meeting booking from any system in the customer stack, pushes data in and pulls structured results
    out, and emits webhooks for real-time automation. The API is marketed on the 11x platform pages but no public reference,
    endpoint list, or machine-readable specification is published; the API host api.11x.ai returns HTTP 403 to anonymous requests.
    Access is arranged through the sales/demo motion.

    with HTTP 403, and the only surviving developer docs are two legacy "Mike" integration pages on an origin whose canonical
