Fideo

Fideo Intelligence is a Denver-based identity intelligence and fraud-prevention platform, spun out of FullContact in 2024 and backed by Foundry Group, Baird Capital, and Blue Note Ventures. Fideo turns fragmented personal identifiers — email, phone, SSN, name, postal address, IP address, and social handles — into real-time fraud and identity-verification signals drawn from an identity graph spanning billions of identities. Its two products, Verify (a single-call, real-time identity-verification and risk-scoring API that runs dozens of checks across breach, sanctions/watchlist, email, phone, location, device, and synthetic-identity dimensions) and Signals (modular identity-intelligence bundles that enrich existing fraud models), serve banks, credit unions, neobanks, fintechs, payments companies, and financial-crime and compliance teams for KYC, AML, onboarding, account-takeover, and payment-fraud use cases. The REST API is served at https://api.fideo.ai with bearer API-key authentication and JSON payloads, and is documented on a ReadMe developer hub.

Fideo is listed with 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Identity Verification, Fraud Prevention, and Identity Intelligence.

Fideo’s developer surface includes engineering blog, documentation, API reference, getting-started guide, signup flow, support, changelog, and 14 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
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
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)

11 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 0.0 — up to +25.0 composite points
Access Clarity scores 42.1 — up to +11.6 composite points
Operational Transparency scores 15.8 — up to +10.9 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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. This rating is computed from the provider profile at artifacts.apis.io/fideo/apis.yml: open an issue on github.com/api-evangelist/fideo to ask a question or point us at an artifact you publish.

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
Biometrics Testing (biometric recognition vendors, identity verification depth)	undeclared	-	-	-

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.
