Robinhood

Robinhood Markets is a US financial-services company offering commission-free trading of stocks, ETFs, options, and cryptocurrency, plus retirement accounts, a cash/spending card, and 24-hour markets. For developers, Robinhood publishes the Crypto Trading API, a REST interface at trading.robinhood.com that lets an account holder view buying power and holdings, pull market data (best bid/ask and estimated fill prices), enumerate supported trading pairs, and place, retrieve, and cancel crypto orders (market, limit, stop-loss, and stop-limit). The API authenticates each request with an API key plus an Ed25519 request signature carried in the x-api-key, x-timestamp, and x-signature headers. Robinhood was added to the API Evangelist network as a VC-portfolio lead and enriched from its public developer surface.

Robinhood publishes 5 API contracts indexed on the APIs.io network, including Account API, Holdings API, Market Data API, and 2 more. Tagged areas include Company, Fintech, Cryptocurrency, Trading, and Brokerage.

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

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

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
Capital Markets and Trading	regulated	56.0	-	-
Asset and Wealth Management	regulated	56.0	-	-
EU/EEA Payment and E-Money Institutions (PSD2 passports)	regulated	56.0	-	-

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.
