Quickstart

import asyncio
import os
from agentlattice import AgentLattice

al = AgentLattice(api_key=os.environ["AL_API_KEY"])

async def main():
    # gate() blocks until approved — your agent code only runs if it passes
    await al.gate("pr.merge")
    await merge_pr(42)

asyncio.run(main())

Handle denials and timeouts:

from agentlattice import AgentLattice, AgentLatticeDeniedError, AgentLatticeTimeoutError

al = AgentLattice(api_key=os.environ["AL_API_KEY"])

async def main():
    try:
        await al.gate("code.commit")
    except AgentLatticeDeniedError as e:
        print(f"Denied: {e.reason}, policy: {e.policy}")
        print(f"Failed conditions: {e.conditions}")
    except AgentLatticeTimeoutError as e:
        print(f"Approval timed out: {e.approval_id}")

asyncio.run(main())

Sync usage

If you're not in an async context:

import os
from agentlattice import AgentLattice

al = AgentLattice(api_key=os.environ["AL_API_KEY"])
al.gate_sync("code.commit")

---

Core API

AgentLattice(api_key, *, base_url?, gate_poll_timeout_ms?, gate_poll_interval_ms?)

Parameter	Default	Description
api_key	required	Bearer token — pass via os.environ["AL_API_KEY"], never hardcoded
base_url	https://www.agentlattice.io	Override for self-hosted or staging
gate_poll_timeout_ms	8 * 60 * 60 * 1000 (8 hours)	How long gate() polls for approval
gate_poll_interval_ms	5000	Poll interval in ms

---

await al.execute(action_type, options?)

Submit an action and return immediately. Returns an ActionResult. Does not block.

from agentlattice import AgentLattice, ActionOptions

al = AgentLattice(api_key="al_...")
result = await al.execute("pr.open", ActionOptions(
    data_accessed=[{"type": "source_code", "count": 5, "sensitivity": "low"}],
    metadata={"pr_number": 42},
    event_id="my-idempotency-key",   # optional: dedup by your own key
))

if result.status == "executed":
    print(f"Auto-executed under policy: {result.policy_name}")
elif result.status == "requested":
    print(f"Awaiting approval: {result.approval_id}")
elif result.status == "denied":
    print(f"Denied ({result.denial_reason}): {result.conditions_evaluated}")

---

await al.gate(action_type, options?)

Submit an action and block until it is approved or denied.

try:
    await al.gate("pr.merge")
except AgentLatticeDeniedError as e:
    # e.reason:     "CONDITIONS_DENIED" | "POLICY_TAMPERED" | "DENIED_BY_REVIEWER"
    # e.policy:     name of the governing policy (if conditions-based)
    # e.conditions: list of ConditionResult (which rule failed and why)
    # e.approval_id: set if a human reviewer denied it
    ...
except AgentLatticeTimeoutError as e:
    # e.approval_id: the approval that timed out
    ...

Sync: al.gate_sync(action_type, options?) / al.execute_sync(action_type, options?)

---

ActionResult

@dataclass
class ActionResult:
    status: str                          # "executed" | "requested" | "denied" | ...
    audit_event_id: str
    approval_id: str | None              # set when status="requested"
    message: str | None
    timeout_at: str | None
    denial_reason: str | None            # "CONDITIONS_DENIED" | "POLICY_TAMPERED" | ...
    policy_name: str | None              # governing policy name
    conditions_evaluated: list[ConditionResult]  # which rules passed/failed

ConditionResult

@dataclass
class ConditionResult:
    field: str       # e.g. "pr_size"
    operator: str    # e.g. "lt"
    expected: Any    # e.g. 100
    result: bool     # True = passed, False = failed

Agents can read conditions_evaluated to understand exactly which governance rule blocked them and adapt their behavior accordingly.

Delegation — Scoped Sub-Agents

Create short-lived child agents with narrowed capabilities. Cleanup is automatic.

async with al.delegate("data-processor",
    capabilities=["read_data", "write_results"],
    ttl=300
) as sub:
    await sub.execute("read_data")
    result = await sub.execute("write_results")

Sync version:

with al.delegate_sync("data-processor",
    capabilities=["read_data"], ttl=300
) as sub:
    sub.execute_sync("read_data")

al.delegate(name, *, capabilities, ttl)

Parameter	Description
name	Display name for the ephemeral child agent
capabilities	List of action types the child can perform (must be subset of parent's)
ttl	Time-to-live in seconds (max 86400 = 24 hours)

Returns an async context manager yielding a DelegatedAgent. Cleanup runs in __aexit__ regardless of exceptions.

DelegatedAgent

Method	Description
sub.execute(action_type, options?)	Execute an action as the child
sub.gate(action_type, options?)	Execute + block until approved
sub.delegate(name, *, capabilities, ttl)	Chain further with narrower scope

All methods have _sync variants.

Parallel fan-out

async with AgentLattice.parallel(
    al.delegate("reader-1", capabilities=["read_data"], ttl=60),
    al.delegate("reader-2", capabilities=["read_data"], ttl=60),
) as [r1, r2]:
    result_1 = await r1.execute("read_data")
    result_2 = await r2.execute("read_data")

See docs/ephemeral-agents.md for architecture details, security model, and cleanup guarantees.

---

Introspection & Governance

These methods give agents visibility into their own identity, policies, audit trails, and governance posture. Every method has a *_sync() variant.

await al.whoami()

Returns this agent's identity, active policies, and delegation relationships.

info = await al.whoami()
print(f"Agent: {info.name} ({info.config_id})")
print(f"Circuit breaker: {info.cb_state}")
print(f"Policies: {[p.name for p in info.policies]}")

---

await al.policies(scope?)

List policies. scope="own" (default) returns policies for this agent. scope="org" returns all org policies.

result = await al.policies(scope="org")
for p in result.policies:
    print(f"{p.name}: {p.action_type} (approval={p.approval_required})")

---

await al.can_i(action_type)

Dry-run policy check. No audit event created, no approval requested.

check = await al.can_i("pr.merge")
if check.allowed:
    print("Good to go")
elif check.needs_approval:
    print(f"Will need approval under policy: {check.policy_name}")

---

await al.audit(cursor?, limit?, action_type?)

Query the audit trail with pagination.

page = await al.audit(limit=50, action_type="pr.merge")
for event in page.events:
    print(f"{event.timestamp}: {event.action_type} -> {event.status}")
if page.next_cursor:
    next_page = await al.audit(cursor=page.next_cursor)

---

await al.verify()

Verify the org's audit chain integrity (tamper detection).

result = await al.verify()
if not result.chain_valid:
    print(f"Chain broken at row: {result.first_broken_at_row_id}")

---

await al.delegations(role?, active_only?)

List delegations. Filter by role="parent" or role="child", and active_only=False to include expired.

result = await al.delegations(role="parent", active_only=False)
for d in result.delegations:
    print(f"{d.id}: active={d.active}, expires={d.expires_at}")

---

await al.revoke(delegation_id)

Revoke a delegation by ID.

result = await al.revoke("del-abc123")
assert result.revoked

---

await al.report(audit_event_id, outcome)

Report the outcome of a previously executed action. Closes the audit loop.

from agentlattice import ReportOutcome

result = await al.report(
    "evt-abc123",
    ReportOutcome(status="success", message="Deployed to prod"),
)
print(f"Reported at: {result.reported_at}")

Outcome statuses: "success", "failure", "partial".

---

await al.posture()

Get the org's governance posture score (0-100).

result = await al.posture()
print(f"Score: {result.score}/100")
for name, comp in result.components.items():
    print(f"  {name}: {comp.score}/{comp.max}")

---

Realtime Events

Subscribe to governance events via WebSocket. Requires pip install agentlattice[realtime].

from agentlattice import AgentLattice, GovernanceEvent

al = AgentLattice(api_key=os.environ["AL_API_KEY"])

def on_event(event: GovernanceEvent):
    print(f"[{event.event_type}] agent={event.agent_id} data={event.data}")

await al.subscribe("org-id", on_event)

# Filter to specific event types
await al.subscribe("org-id", on_event, events=["action.denied", "anomaly.detected"])

# Filter to a specific agent
await al.subscribe("org-id", on_event, agent_filter="agent-123")

# Cleanup
await al.unsubscribe()

Event types: action.denied, action.executed, delegation.expired, delegation.revoked, policy.changed, anomaly.detected, enforcement.triggered.

Patterns

Self-correcting agent

conditions_evaluated is what makes this more than a compliance layer — it closes the feedback loop so agents can adapt, not just fail.

from agentlattice import AgentLattice, AgentLatticeDeniedError, ActionOptions

al = AgentLattice(api_key=os.environ["AL_API_KEY"])

async def commit_with_governance(files: list[str]) -> None:
    try:
        await al.gate("pr.open", ActionOptions(
            metadata={"pr_size": len(files), "repo": "acme/backend"},
        ))
        await open_pr(files)

    except AgentLatticeDeniedError as e:
        if e.reason == "CONDITIONS_DENIED":
            # Find which rules failed and why
            failed = [c for c in e.conditions if not c.result]
            # e.g. [ConditionResult(field="pr_size", operator="lt", expected=50, result=False)]

            for rule in failed:
                if rule.field == "pr_size":
                    # Policy says PRs must be < 50 files — split and retry
                    mid = len(files) // 2
                    await commit_with_governance(files[:mid])
                    await commit_with_governance(files[mid:])
                    return

        # Reviewer denial or policy tamper — no retry
        raise

Error Hierarchy

AgentLatticeError          base — code, message, details
  AgentLatticeDeniedError  approval_id?, reason?, policy?, conditions?
  AgentLatticeTimeoutError approval_id

Reliability

execute() and gate() retry automatically on 5xx and network errors — up to 3 attempts with 1s/2s/4s exponential backoff. Each request has a 30-second timeout. Pass event_id to make retries idempotent.

execute_sync() and gate_sync() are safe in async runtimes (LangGraph, FastAPI, CrewAI) — they detect a running event loop and dispatch to a thread pool automatically.
