Semasio
Semasio is a Hamburg, Germany advertising-technology company whose semantic targeting platform builds audience, contextual and brand-fit segments for brands, agencies and DSPs across roughly 30 languages and 50 countries. Founded in 2010, it was acquired in 2022 by Casters Holdings, Inc. operating under the Fyllo brand; the combined business traded as Fyllo|Semasio, rebranded to Semasio in April 2024, and was acquired by Samba TV on 31 October 2024. Products include Audience Targeting, Audience Extension, Contextual Targeting, ContextualPLUS, Brand Fit, Interactive Screens, HypertailPMP and the Semasio Factory data onboarding and modeling service. Semasio operates a login-only platform (uip.semasio.net) behind an authentik single sign-on host and publishes no public developer program, API reference, SDK or machine-readable specification.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Semasio the way a machine reads it — 3 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Semasio scores 12.4/100 (minimal), with a separate agent-readiness read of 3/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
Semasio's entire 324-page sitemap is marketing, legal, case-study and podcast content with no developer, API or documentation path, and the only non-marketing hosts it operates — the uip.semasio.net platform UI, which serves a disallow-all robots.txt, and an authentik single sign-on at auth.semasio.net — return 404 for every OpenAPI, GraphQL, MCP and agent-card path probed.
This is an honest zero, not a gap in our research. Semasio does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Semasio
Each block below is one kind of artifact we hold for Semasio. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.
Fyllo Plans Pricing
PLANSRate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
Fyllo Rate Limits
RATE LIMITSSecurity Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Semasio, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
