Sybilion

Sybilion is a decision layer for industrial companies, providing economic and causal forecasting that connects external market dynamics to internal exposure for procurement, trading and risk teams. It forecasts monthly business time series up to twelve months ahead with 80% and 90% quantile bands, ranks the external macroeconomic drivers that move a series with Granger lag relationships and feature-importance scores, backtests against the last twelve months, and raises alerts on the market movements turning relevant to a customer's exposure right now. The same causal model is reachable two ways: an anonymously-specified OpenAPI 3.0.3 REST API at api.sybilion.dev using Bearer API keys, and a hosted OAuth MCP server at mcp.sybilion.dev that ChatGPT, Claude and the TradingView Remix extension connect to directly. Billing is a prepaid EUR-cent balance with expiring credit tranches and pre-flight holds. Official Python, Go, TypeScript and R SDKs are published.

Sybilion publishes 10 API contracts indexed on the APIs.io network, including Alerts API, Categories API, Drivers API, and 7 more. Tagged areas include Industrial market intelligence, Commodity price forecasting, Economic Forecasting, Time-series forecasting, and Procurement.

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

Sybilion’s developer surface includes pricing, documentation, API reference, getting-started guide, support, engineering blog, signup flow, and 26 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 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):

A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Pagination +5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs
Agentic Commerce Well-Known Document +5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service, OR (0.27) a live x402 payment challenge from _data/x402-adoption.json — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's
Dry-Run / Simulate Mode +4 pts — OpenAPI: destructive operations expose a dry_run / simulate / preview / validate_only parameter

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
Procurement and B2B Buying (source-to-pay suites, spend management)	distribution	9.6 (thin)	-	-

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.
