The problem

AI agents making decisions about hiring, credit scoring, data processing, or content moderation are operating under dozens of overlapping regulations — GDPR, EU AI Act, HIPAA, CCPA, Basel III. When an agent gets the legal logic wrong, it isn't just a bug. It's a regulatory liability event.

LLMs hallucinate regulations. bidda-shield is built to reduce that risk by giving the model a source-verified answer to ground on instead of its own recall.

Every compliance node in the Bidda registry traces to a specific clause of a primary legal instrument, verified against the source URL, and drift-checked weekly. Nodes are built by Bidda's own deterministic pipeline: internal parsers and multi-gate verification scripts do the heavy lifting, and any AI assistance is confined to a small, tightly-gated drafting step that every node must clear across several independent checks before it ships. The whole design exists to keep drift to a minimum. No inference. No approximation.

5-minute quickstart

pip install bidda-shield

from bidda_shield import BiddaShield

shield = BiddaShield(api_key="your-bidda-api-key")

# 1. Search the registry (free, no quota hit)
hits = shield.search_nodes("biometric data EU")
print(hits[0]["title"])     # EU AI Act Article 5 — Prohibited AI Practices
print(hits[0]["bluf"])      # Plain-English summary

# 2. Pre-flight compliance check (free, the headline tool)
verdict = shield.check_action_compliance(
    "process EU resident biometric data for access control",
    jurisdiction="eu",
)
print(verdict["risk_level"])   # "HIGH"
print(verdict["match_count"])  # 10

# 3. Unlock the full machine-executable workflow for the top match ($0.01)
top = verdict["matches"][0]
node = shield.get_node(top["node_id"], vault=True)
for step in node["deterministic_workflow"]:
    print(step["step"], step["action"])

That's it. The pattern: search → check → unlock. Free everywhere except the final unlock.

LangChain

from langchain.agents import initialize_agent, AgentType
from langchain_openai import ChatOpenAI
from bidda_shield import BiddaLangChainTool

llm  = ChatOpenAI(model="gpt-4o")
tool = BiddaLangChainTool()

agent = initialize_agent(
    tools=[tool],
    llm=llm,
    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
    verbose=True,
)

agent.run(
    "My agent is about to make an automated credit decision. "
    "What regulations apply and what do they require?"
)

The tool returns the regulation title, domain, plain-English summary (BLUF), and a link to the full verified node — for $0.01 USDC per full unlock.

user_proxy.initiate_chat(
    assistant,
    message="What does GDPR Article 22 require for automated decision-making?",
)

    tools=[compliance_tool],
    verbose=True,
)

task = Task(
    description="Review the agent action 'train a model on employee performance data' and identify all applicable regulations.",
    agent=compliance_officer,
)

crew = Crew(agents=[compliance_officer], tasks=[task])
crew.kickoff()

Full method reference (v0.10.1 - full 25-tool MCP parity)

Every tool exposed by the bidda.com/mcp MCP server is available as a Python method. Results match what an MCP client would see for the same input — the SDK mirrors the same logic, just returning structured dict / list data instead of LLM-formatted markdown.

from bidda_shield import BiddaShield
shield = BiddaShield()

# 1. Browse the registry
shield.list_pillars()                              # → ["AI Governance & Law", ...]
shield.search_nodes("biometric", pillar="ai-gov")  # → [{"node_id", "title", ...}, ...]
shield.get_node("gdpr-article-22-automated-decisions")  # discovery (free)
shield.get_node("gdpr-article-22-automated-decisions", vault=True)  # full ($0.01)

# 2. Walk prerequisites — what does this rule depend on?
shield.get_dependency_chain("eu-ai-act-article-10-data-governance-training", max_depth=2)
# → {"root": "...", "title": "...", "chain": [{"depth": 0, ...}, ...], "total": 8}

# 3. Cross-framework mappings — GDPR Art 17 → CCPA right-to-delete → POPIA Sec 24
shield.get_crosswalk("gdpr-article-17-right-to-erasure")
# → {"node_id", "title", "dimensions": ["ccpa_equivalent", ...], "vault_url"}

# 4. Regulatory change feed — what moved recently
shield.get_latest_changes(days=30, pillar="Cybersecurity")
# → [{"node_id", "title", "domain", "last_updated"}, ...]  (newest first, max 20)

# 5. Jurisdiction-wide rule bundle — everything that applies in a market
shield.get_jurisdiction_bundle("eu", limit=25)
# → {"jurisdiction", "total_matches", "by_pillar": {...}, "nodes": [...]}

# 6. MITRE technique → compliance mapping
shield.get_mitre_mapping("T1566")           # ATT&CK Enterprise (phishing)
shield.get_mitre_mapping("AML.T0020")       # ATLAS (AI-specific)
shield.get_mitre_mapping("D3-FIM")          # D3FEND defensive
shield.get_mitre_mapping("CAPEC-66")        # CAPEC attack pattern
# → [{"node_id", "title", "bluf", "dependencies", "crosswalk_dimensions", "vault_url"}, ...]

# 7. Pre-flight compliance check — primary agent runtime tool
result = shield.check_action_compliance(
    "process EU resident biometric data for access control",
    jurisdiction="eu",
    limit=10,
)
# → {
#     "action": "...",

#     ]
#   }

if result["risk_level"] == "HIGH":
    # Halt the agent action, surface the matched regulations to a human.
    raise RuntimeError(f"Compliance gate failed: {result['match_count']} matches")

Subscriber tools (pass api_key= — a free trial counts)

# 8. Browse the registry by cross-cutting compliance topic (free, no key)
shield.browse_topics("data breach notification")
# → [{"node_id", "title", "pillar", "jurisdiction"}, ...] across every pillar

# 9. Compare how jurisdictions address one topic, including where numeric
#    thresholds differ (e.g. 72 hours vs 30 days). Does not rank strictness.
shield.compare_jurisdictions("data breach notification", api_key="YOUR_BIDDA_KEY")

# 10. Signed, time-stamped record of which rules a person or agent relied on
shield.create_attestation(
    agent="loan-bot-v2",
    nodes=["gdpr-article-22-automated-decisions"],
    api_key="YOUR_BIDDA_KEY",
)
# → {"id", "signature", "verify_url", "created_at"}

# 11. Signed record of which committed version was authoritative at a past date
shield.point_in_time("gdpr-article-22-automated-decisions", at="2026-01-15", api_key="YOUR_BIDDA_KEY")

# 12. Subscribe to email/webhook alerts when a watched rule's source changes
shield.watch_changes(node_id="eu-ai-act-article-13-transparency", email="you@org.com", api_key="YOUR_BIDDA_KEY")

Run ledger — a signed log of a whole task or conversation

A single attestation covers one decision. A run covers a whole task or conversation (for example a support-bot chat). Open a run, record one entry per turn as the agent consults rules and answers, then seal it into one signed run receipt that covers every turn. The end user's input can be stored as text, or privately as a hash that never leaves your process.

# Easiest: a context manager that opens on enter and seals on exit.
with shield.run(agent="acme-support-bot", label="chat 8f21") as run:
    run.record(
        user_input="Can you delete all my data?",
        nodes=["eu-gdpr-article-17-right-to-erasure"],
        decision="explained erasure right + 30-day window",
    )
    run.record(
        user_input="And confirm in writing?",
        hash_only=True,                 # stores only a sha256 of the message
        decision="confirmed email follow-up",
    )
receipt = run.receipt                   # signed; covers both turns
print(receipt["receipt_id"], receipt["verify_url"])

# Or call the four methods directly:
# 13. open_run        -> {"run_id", ...}
# 14. record_run_entry(run_id, nodes=, decision=, note=, input_hash=, ...)
# 15. seal_run(run_id) -> signed run receipt with a public verify_url
# 16. get_run(run_id)  -> the run + entries (a sealed run reports signature_valid)
opened = shield.open_run(agent="acme-support-bot", label="chat 8f21", api_key="YOUR_BIDDA_KEY")
shield.record_run_entry(opened["run_id"], nodes=["eu-gdpr-article-17-right-to-erasure"],
                        note="User: delete my data", decision="explained", api_key="YOUR_BIDDA_KEY")
sealed = shield.seal_run(opened["run_id"], api_key="YOUR_BIDDA_KEY")

Anyone you hand the receipt to can verify it against Bidda's public key with no Bidda account. Opening, recording and sealing need an active subscription (a free trial counts); verifying a sealed receipt is free.

Governed runs - consult a rule and record the proof in one call

with shield.run(agent="loan-bot-v2", label="application 4411") as run:
    # 17. Run.consult: fetch the full node AND record a verified, hash-pinned
    #     run entry in one step. The sealed receipt then proves exactly which
    #     version of the rule the agent read.
    node = run.consult(
        "eu-gdpr-article-22-automated-decisions",
        decision="routed to human review",
        model="gpt-5.2",          # optional: which model decided
        subject="user-8812",      # optional: stored only as a private hash
    )
# 18. audit_pack: one auditor-ready evidence pack for a sealed run - the signed
#     receipt, the entry chain, and an independent integrity self-check.
pack = shield.audit_pack(run.receipt["run_id"])   # also available as run.audit_pack()

Governance tools

# 19. drift_check: is the law this agent cached still current? Pass the
#     anchors you stored when you grounded ({"node_id", "hash"}); each comes
#     back fresh, drifted, or withdrawn.
shield.drift_check([{"node_id": "eu-ai-act-article-10-data-governance-training",
                     "hash": "sha256:..."}])

# 20. create_control_attestation: sign a record mapping one of YOUR controls
#     to the obligations it addresses. An audit trail, not a determination.
shield.create_control_attestation(
    control="Access review",
    statement="Quarterly review of privileged access.",
    nodes=["iso-27001-annex-a-access-control"],
    framework="ISO 27001", control_owner="Jane Smith", control_status="operating",
)

# 21. gap_check: walk the dependency graph from the rules you cover and
#     surface prerequisite obligations you did not list.
shield.gap_check(["eu-ai-act-article-10-data-governance-training"], depth=2)

# 22. obligation_deltas: which obligations changed at the source since a date.
shield.obligation_deltas(since="2026-06-01", pillar="AI Governance & Law")

# 23. oscal_assessment_results: export a sealed run as a NIST OSCAL
#     assessment-results document for GRC tooling.
shield.oscal_assessment_results(sealed["run_id"])

The discovery index is cached client-side for 5 minutes after the first call, so chained calls (e.g. check_action_compliance followed by get_dependency_chain on the top match) reuse the same fetch.

What's in a full node

Each vault-tier node contains:

• BLUF — plain-English summary of the legal obligation
• deterministic_workflow — step-by-step compliance checklist derived from the primary legal text
• actionable_schema — machine-readable compliance checkpoints
• primary_citations — exact section references to the legal instrument
• crosswalks — mappings to NIST, ISO, and peer standards
• dependencies — other regulations this one depends on or triggers
• verification — source URL, jurisdiction, instrument type, integrity hash

All content traces to a real primary legal source. No secondary commentary. No paraphrasing.

---

Authentication

The vault tier (full 13-key node + workflow + citations) costs $0.01 per node. Three ways to pay:

import os
from bidda_shield import BiddaShield

# 1. Subscription / evaluation key — easiest, recommended for most devs
shield = BiddaShield(api_key=os.getenv("BIDDA_API_KEY"))

# 2. Skyfire JWT — agent-native, autonomous payments
shield = BiddaShield(skyfire_token=os.getenv("BIDDA_SKYFIRE_TOKEN"))

# 3. Direct Base USDC — headless, no account needed
shield = BiddaShield(base_tx_hash="0xYOUR_TRANSACTION_HASH")

Pick one path per client. Discovery tier (search, BLUF, MCP tools) works with no auth at all and is free forever.
