Bidda is the world's first source-verified, cryptographically-signed compliance intelligence registry. 10065 regulatory frameworks across 39 sovereign pillars, including EU AI Act, GDPR, NIST AI RMF, Basel III, HIPAA, DORA, and 150+ others, distilled into machine-executable logic at $0.01 per node.

How does Bidda reduce AI hallucination in compliance?

Every Bidda node is generated from and verified against its primary legal source, meaning the actual legislation, standard, or regulatory instrument. Each node carries a SHA-256 integrity hash and passes a 13-point validation gate and human review before publishing. No secondary commentary. No AI inference without a regulatory anchor.

What does it cost to access Bidda compliance nodes?

$0.01 USDC per full node unlock via Skyfire bearer token, Direct Base USDC, or L402/USDC on Base. The discovery API is free. Pillar bundles are one-time frozen snapshots ranging from $5 (Workflow) to $49 (Cybersecurity / Legal / Finance). A MITRE Frameworks cross-cut bundle (ATT&CK + ATLAS + D3FEND + CAPEC, 204 nodes) is $29. Full registry: enterprise plans only (info@bidda.com). Card checkout via Paystack is coming soon; until live, fiat purchases are invoiced on request.

Which regulations does Bidda cover?

10065 nodes across 39 sovereign pillars, covering EU AI Act, GDPR, NIST AI RMF, ISO/IEC 42001, Basel III/IV, HIPAA, DORA, NIS2, FATF, MiCA, TCFD, SOC 2, ITAR, IMO MARPOL, Solvency II, OECD BEPS Pillar Two, and 150+ other global regulatory frameworks.

Is there a free tool to scan my AI agent code for compliance issues?

Yes. The Bidda Agent Compliance Scanner is a free GitHub Action that scans your PR diffs for AI agent code patterns (LangChain, CrewAI, AutoGen, MCP tool definitions, biometric identification, credit decisioning, HR screening, DORA ICT dependencies) and posts an advisory PR comment linking the relevant compliance nodes from the Bidda registry. It never blocks PRs. Install with: uses: Bidda-Ai/agent-compliance-scanner@v0. Available at https://bidda.com/developers - also distributed as the bidda-shield Python SDK (pip install bidda-shield) and as an MCP server at https://bidda.com/mcp for AI agents.

Does the Bidda compliance scanner send my code to external servers?

No. All pattern matching runs locally on your GitHub-hosted runner. The scanner only sends a pattern_id (e.g. 'langchain-import') to query Bidda's public discovery index. Your code, prompts, diffs, and repo contents never leave your runner. The PR comment is posted using your workflow's built-in GITHUB_TOKEN.

MITRE CAPEC-3: Using Leading 'Ghost' Character Sequences to Bypass Input Filters (Detailed Attack Pattern - Medium Severity)

MITRE CAPEC-3 (Using Leading 'Ghost' Character Sequences to Bypass Input Filters) is a detailed-level attack pattern in the MITRE Common Attack Pattern…

Compliance Node Overview

MITRE CAPEC-3 (Using Leading 'Ghost' Character Sequences to Bypass Input Filters) is a detailed-level attack pattern in the MITRE Common Attack Pattern Enumeration and Classification. Some APIs will strip certain leading characters from a string of parameters. An adversary can intentionally introduce leading "ghost" characters (extra characters that don't affect the validity of the request at the API layer) that enable the input to pass the filters and therefore process the adversary's input. Likelihood of attack: Medium. Typical severity: Medium. Maps to weaknesses CWE-173, CWE-41, CWE-172, CWE-179, and others.
