Rho Protocol

Rho Protocol (Rho Labs) operates Rho X, a decentralized multi-asset trading and settlement layer for on-chain capital markets — interest-rate futures, perpetuals, and tokenized real-world assets tradable from a single cross-margined account. It offers off-exchange collateral custody (BitGo OES or self-custody), zero-gas settlement, and a private cross-chain RFQ swap service (Rho Relay) bridging Ethereum and Canton Network assets. Rho X exposes a REST API, a WebSocket streaming API, an npm SDK, and an official Model Context Protocol (MCP) server for programmatic trading, market data, and account management. Backed by Speedinvest.

Rho Protocol publishes 4 API contracts indexed on the APIs.io network, including Market Data API, Stats API, Trading API, and 1 more. Tagged areas include Company, Trading, DeFi, Derivatives, and Capital Markets.

The Rho Protocol catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Rho Protocol’s developer surface includes documentation, API reference, getting-started guide, authentication, engineering blog, support, and 21 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
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
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
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)

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.
