Loop

Loop is a full-stack, AI-powered logistics data platform that unifies the fragmented operational and financial data of the physical economy. Founded by former Uber Freight leaders Matt McKinney and Shaosu Liu, Loop began in freight audit and payment and has expanded into an intelligence layer spanning freight audit, parcel and carrier-invoice auditing, real-time shipment visibility, parcel contract optimization, carrier payments, and autonomous exception management (DUX and the Exception Agent). The Loop developer platform exposes a REST API (api.loop.com/v1) for ingesting artifacts (invoices, shipment records, purchase orders), resolving business exceptions, managing organizations and factoring/invoicing relationships, and reading payable/receivable invoices and payments, plus a separate Onboarding API and Svix-based webhooks. Loop has raised $210M total, including a $95M Series C, from Valor Equity Partners, 8VC, Founders Fund, Index Ventures, J.P. Morgan Growth Equity, and others.

Loop publishes 14 APIs on the APIs.io network, including artifacts API, artifacts-schema-validated API, business-exceptions API, and 11 more. Tagged areas include Company, Logistics, Supply Chain, Freight, and Freight Audit.

The Loop catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Loop’s developer surface includes authentication, documentation, API reference, getting-started guide, engineering blog, signup flow, and 21 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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 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/.

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 github.com/api-evangelist/loop: open an issue to ask a question, or submit a pull request to add artifacts.
