Totalis

Totalis (totalis.trade), operated by UCALLEDIT, Inc., is a Y Combinator-backed (Spring 2026) derivatives layer for prediction markets. Users pick two to five outcomes across underlying venues like Kalshi and Polymarket and combine them into a single parlay; market makers compete to price the trade through a request-for-quote (RFQ) system, and positions settle in non-custodial Solana vaults with USDC collateral. The Totalis RFQ API is a documented REST + SSE surface with scoped API keys, a WebSocket for post-trade events, and HMAC-signed webhooks — covering markets, quote requests, parlays, portfolio, funds, and market-maker flows.

Totalis publishes 7 API contracts indexed on the APIs.io network, including API Keys API, Markets API, Portfolio API, and 4 more. Tagged areas include Company, Prediction Markets, Derivatives, Parlays, and Trading.

The Totalis catalog on APIs.io includes 2 event-driven AsyncAPI specifications and 1 Spectral governance ruleset.

Totalis’ developer surface includes engineering blog, documentation, API reference, getting-started guide, signup flow, pricing, FAQ, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data 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):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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
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)
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

5 more unmet checks in the Agent Readiness table above.

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)	undeclared	-	-	1

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 1

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.
