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
The domain 'keybaseapi.com' impersonates Keybase, a legitimate identity and cryptography service at keybase.io. The addition of 'api' creates a convincing lookalike domain that could deceive users and AI agents into trusting it as an official Keybase API endpoint. (location: domain: keybaseapi.com)
credential harvesting
The domain mimics the Keybase brand and targets the 'API' surface, which is a common vector for harvesting API keys, tokens, or cryptographic credentials from developers and automated agents that integrate with Keybase services. (location: domain: keybaseapi.com)
phishing
TLS is not connected and the certificate is invalid (connected=false, cert_valid=false), meaning any credentials or data submitted to this domain would be transmitted insecurely. Combined with the brand impersonation, this is consistent with a phishing infrastructure. (location: metadata.json: tls block)
malicious redirect
The site returns no HTML content and no visible text despite being reachable enough for metadata to be collected. An empty page is consistent with a site used as a redirect intermediary, a placeholder for future malicious deployment, or a page that only activates under specific conditions (e.g., targeted user-agent or referrer). (location: page.html, page-text.txt (empty content))
curl https://api.brin.sh/domain/keybaseapi.comCommon questions teams ask before deciding whether to use this domain in agent workflows.
keybaseapi.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.
