Jack & Jill

Jack & Jill is an AI hiring platform built around two complementary AI agents. Jack is a free AI career agent for candidates: it scans roughly 15 million jobs daily, runs mock interviews, benchmarks salary, offers career-clarity coaching, and introduces candidates directly to hiring managers, staying fiduciary to the candidate. Jill is an AI recruiter for companies: a hiring team briefs Jill on a role and it returns a curated shortlist from Jack's network of 302,000+ pre-vetted professionals (engineers, product, design, marketing, sales, operations, leadership) within minutes, handling outreach, scheduling, and pipeline management. Operated by Tinker Tailor Talent Ltd. (founded 2024, London and San Francisco), the company raised a $20M seed round led by Creandum. Pricing is a 10% success fee on first-year base salary charged only on a successful hire, with a three-month full-refund guarantee; free for candidates. There is no public developer API today (confirmed via the site's ai.txt); this profile captures the company's real published web, AI-discovery, and security surface.

Jack & Jill is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Recruiting, Hiring, and Talent.

Jack & Jill’s developer surface includes documentation, pricing, signup flow, engineering blog, support, and 14 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Employment & Payroll regime (on an ambiguous tag, where no other regime matched), 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 26.2 — up to +14.8 composite points
Contract Governance scores 0.0 — up to +12.0 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/jack-and-jill/apis.yml: open an issue on github.com/api-evangelist/jack-and-jill to ask a question or point us at an artifact you publish.
