Bonsai

Bonsai (hellobonsai.com) is an all-in-one business management platform for service businesses -- freelancers, agencies, and firms -- consolidating client management (CRM, pipeline, proposals, contracts, forms, client portal), project management (tasks, Gantt, time tracking, timesheets, resource planning), and financial management (invoicing, payments, expenses, bookkeeping, rate cards, budgeting and profitability) into one system. Used by 500,000+ small businesses globally. Bonsai exposes its programmatic surface through an official hosted MCP (Model Context Protocol) server at mcp.hellobonsai.com so AI clients (Claude, ChatGPT, Gemini, Cursor, Codex) can act on tasks, projects, deals, contacts, time entries and invoices; a public REST API is documented as forthcoming. Backed by Matrix Partners.

Bonsai is profiled on the APIs.io network. Tagged areas include Company, B2B, Business Management, Freelancing, and Agencies.

Bonsai’s developer surface includes authentication, documentation, pricing, signup flow, engineering blog, support, and 12 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
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

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