ERPNext

ERPNext is a free and open-source enterprise resource planning (ERP) platform built on the Frappe Framework. It provides a comprehensive REST API for managing accounting, inventory, manufacturing, sales, purchase, HR, and CRM modules. The Frappe Framework auto-generates RESTful endpoints for all DocTypes, supporting standard HTTP methods with JSON responses, token-based authentication, OAuth2, and flexible filtering and pagination.

ERPNext publishes 3 API contracts indexed on the APIs.io network: Method API, Naive Authentication API, and Resource API. Tagged areas include ERP, Accounting, Inventory, Manufacturing, and Sales.

The ERPNext catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

ERPNext’s developer surface includes authentication, documentation, engineering blog, pricing, and 12 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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
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
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

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