Nixtla

Nixtla is an enterprise time-series intelligence platform built around TimeGPT, the first foundation model for time series. Through a simple REST API and Python/R SDKs it delivers zero-shot forecasting (no training data required), batch and real-time anomaly detection, cross-validation, and fine-tuning of the foundation model on customer data. The Nixtla Forecast API (OpenAPI 3.1) exposes /v2 endpoints for forecasting, anomaly detection, online anomaly detection, cross-validation, fine-tuning, and fine-tuned-model management, authenticated with a bearer API key. Nixtla also maintains a widely used open-source forecasting ecosystem (StatsForecast, NeuralForecast, MLForecast, HierarchicalForecast, CoreForecast) with tens of millions of downloads, offers cloud, self-hosted, and air-gapped deployments, ships MCP tools for agentic time-series workflows, and is SOC 2 Type II compliant. Nixtla is backed by Techstars and True Ventures.

Nixtla publishes 8 API contracts indexed on the APIs.io network, including Anomaly Detection API, Cross Validation API, Excluded API, and 5 more. Tagged areas include Company, Time Series, Forecasting, Anomaly Detection, and Machine Learning.

The Nixtla catalog on APIs.io includes 1 Spectral governance ruleset.

Nixtla’s developer surface includes documentation, API reference, getting-started guide, authentication, changelog, engineering blog, pricing, and 25 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 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):

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)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
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.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Official R Client Packages on CRAN	distribution	28.8	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
