Webz.io provides structured web-data feeds and APIs covering the open, deep, and dark web for AI, cybersecurity, and intelligence use cases. Content is collected at scale, normalized, enriched with metadata, and delivered through machine-readable data feeds and token-authenticated REST APIs.
Webz.io is listed with 13 APIs on the APIs.io network. Tagged areas include News Data, Web Data, Web Scraping, Dark Web, and deep-web.
Webz.io’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, pricing, and 27 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/.
Show this score on your site.
It updates itself when the score changes. Paste this where you link to your API docs:
<a href="https://apis.io/providers/webz/"><img src="https://apis.io/badge/webz/card.svg" alt="Webz.io on APIs.io — Kin Score by API Evangelist"></a>
Other styles, a README pill and a shields.io endpoint are on the badge page.

Agent readiness — checks not met, largest first (exact, from this profile):
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
Typed Event Surface+6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
5 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
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.
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.

description: 'Token-authenticated REST endpoints under https://api.webz.io covering seven products: News, Blogs and Forums
(/api/news, /api/blogs, /api/forums plus /seg_api/* segmentation), Reviews (/reviewFilter, /reviewSeg), Cyber for deep
and dark web (/cyberFilter, /cyberSeg, /dark-cache, /cyber-image), Data Breaches (/breaches, /breachCatalog), the Firehose
FH API (/firehose), the semantic News Search API (POST /api/news/context), and the Archive order flow on app.webz.io.
All are GET except News Search. Responses are a JSON envelope wrapping a result array plus an opaque next cursor. A free
News API Lite tier gives 1,000 non-commercial calls a month.
NO OpenAPI, Swagger, GraphQL, AsyncAPI, WSDL or apis.json contract is published. Re-probed 2026-08-27 across api.webz.io,
webz.io and docs.webz.io: /openapi.json, /openapi.yaml, /swagger.json, /api-docs, /docs, /reference and /apis.json all
404. WHAT IS PUBLISHED and is new since the last pass: a first-party remote MCP server at https://news-search-mcp.webz.io/mcp
with RFC 8414 and RFC 9728 discovery metadata (both probed 200), a provider-authored Agent Skill file, and a 20KB llms.txt
indexing every docs page with a Markdown twin. The machine-readable surface here is agent-native rather than OpenAPI-native.'

description: A first-party remote Model Context Protocol server that exposes Webz.io semantic news search to any MCP client.
It ships one tool, news_search_by_webz, and every call runs a regular News Search API request against the caller's own
Webz token, so the same credits and per-token rate limits apply. Authentication is a Bearer API token; Claude.ai and ChatGPT
connect over OAuth, and the server publishes RFC 8414 authorization-server metadata and RFC 9728 protected-resource metadata
(both probed 200 on 2026-08-27) with PKCE S256 and dynamic client registration. An anonymous tools/list returns 401 with
a correctly-formed WWW-Authenticate challenge, which the provider documents as intentional.
