context safety score
A score of 46/100 indicates multiple risk signals were detected. This entity shows patterns commonly associated with malicious intent.
tls connection failed
Could not establish TLS connection
brand impersonation
Domain 'toutiaoapi.com' impersonates the legitimate Toutiao (ByteDance) API service. The name closely mimics the real toutiao.com platform and its official API infrastructure, potentially deceiving developers or AI agents into treating it as an official ByteDance/Toutiao endpoint. (location: domain: toutiaoapi.com)
malicious redirect
TLS connection failed entirely (connected=false, cert_valid=false, san_match=false) for a domain presenting itself as an API service. A site impersonating a major API provider that cannot establish a valid TLS connection is highly anomalous and consistent with a deceptive endpoint designed to intercept or redirect API traffic without secure transport. (location: metadata.json: tls object)
credential harvesting
The combination of brand impersonation of a major API platform (Toutiao/ByteDance) with no valid TLS and completely empty page content is consistent with a credential-harvesting or API key interception setup. Developers or AI agents configured to call 'toutiaoapi.com' as a supposed official API endpoint may inadvertently send authentication tokens or API keys over an insecure or adversary-controlled channel. (location: domain: toutiaoapi.com, metadata.json: tls object)
phishing
The domain serves no content (empty page.html and page-text.txt) while presenting as an API domain. This blank-page pattern with a misleading domain name is consistent with a phishing infrastructure host that may be used selectively or is in a dormant/staging phase awaiting deployment of a phishing payload. (location: page.html, page-text.txt (empty content))
curl https://api.brin.sh/domain/toutiaoapi.comCommon questions teams ask before deciding whether to use this domain in agent workflows.
toutiaoapi.com currently scores 46/100 with a suspicious verdict and medium confidence. The goal is to protect agents from high-risk context before they act on it. Treat this as a decision signal: higher scores suggest lower observed risk, while lower scores mean you should add review or block this domain.
Use the score as a policy threshold: 80–100 is safe, 50–79 is caution, 20–49 is suspicious, and 0–19 is dangerous. Teams often auto-allow safe, require human review for caution/suspicious, and block dangerous.
brin evaluates four dimensions: identity (source trust), behavior (runtime patterns), content (malicious instructions), and graph (relationship risk). Analysis runs in tiers: static signals, deterministic pattern checks, then AI semantic analysis when needed.
Identity checks source trust, behavior checks unusual runtime patterns, content checks for malicious instructions, and graph checks risky relationships to other entities. Looking at sub-scores helps you understand why an entity passed or failed.
brin performs risk assessments on external context before it reaches an AI agent. It scores that context for threats like prompt injection, hijacking, credential harvesting, and supply chain attacks, so teams can decide whether to block, review, or proceed safely.
No. A safe verdict means no significant risk signals were detected in this scan. It is not a formal guarantee; assessments are automated and point-in-time, so combine scores with your own controls and periodic re-checks.
Re-check before high-impact actions such as installs, upgrades, connecting MCP servers, executing remote code, or granting secrets. Use the API in CI or runtime gates so decisions are based on the latest scan.

Assessments are automated and may contain errors. Findings are risk indicators, not confirmed threats. This is a point-in-time assessment; security posture can change.
