Decision intelligence layer for AI agents — Layerinfinite

Layerinfinite Python SDK

Decision intelligence middleware for AI agents. Records action outcomes, learns which actions work best per task, and recommends the highest-performing action — with zero LLM dependency.

Drop it into any agent in minutes. It learns silently in the background and gets smarter with every run.

Installation

pip install layerinfinite-sdk

Get your API key at layerinfinite.ai.

Quick Start

from layerinfinite import Layerinfinite

li = Layerinfinite(api_key="layerinfinite_xxx", agent_id="my-agent")

@li.action("payment_failed")
def retry_payment(ticket_id):
    return gateway.charge(ticket_id)

@li.action("payment_failed")
def switch_provider(ticket_id):
    return alt_gateway.charge(ticket_id)

# That's it. Every call is logged automatically.
retry_payment("t-001")

LI records success/failure and latency on every call. After ~50 outcomes it starts recommending the best action per task.

Modes

recommend (default) — observe and learn

li = Layerinfinite(api_key="...", agent_id="my-agent", mode="recommend")

# Your agent runs normally. LI logs every outcome silently.
# After enough data, ask for a recommendation:
rec = li.recommend("payment_failed")
print(rec.recommendation)   # "switch_provider has 82% success vs 51% for retry_payment"
print(rec.state)            # "active_recommendation"

assist — LI suggests, you decide

li = Layerinfinite(api_key="...", agent_id="my-agent", mode="assist")

suggestion = li.suggest("payment_failed")
print(suggestion.action_name)   # "switch_provider"
print(suggestion.confidence)    # 0.87
print(suggestion.outcomes_needed)  # 0 — fully active

# You still decide what to execute.

auto — LI picks and executes

li = Layerinfinite(api_key="...", agent_id="my-agent", mode="auto")

# One line. LI picks the best action, runs it, logs the outcome.
result = li.run("payment_failed")

All Methods

Method	Modes	Description
@li.action(task, name=None)	all	Decorator — auto-logs every call's outcome
li.run(task)	auto	Pick, execute, log — fully autonomous
li.suggest(task)	assist	Best action suggestion without executing
li.recommend(task)	all	Plain-English recommendation from outcome data
li.scores(task)	all	Raw ranked action scores
li.observe(task)	all	Quick outcome stats (total runs, success rate, best/worst)
li.log_outcome(request)	all	Manual outcome logging for power users
li.list_actions(task)	all	List registered actions
Layerinfinite.normalize_task(value)	—	"Payment Failed" → "payment_failed"
Layerinfinite.normalize_business_outcome(value)	—	"ok" → "resolved", "error" → "failed"

Constructor Parameters

Layerinfinite(
    api_key="layerinfinite_xxx",     # required — from layerinfinite.ai
    agent_id="my-agent",             # required — identifies your agent
    mode="recommend",                # recommend | assist | auto
    confidence_threshold=0.7,        # minimum confidence before LI acts
    auto_fallback=True,              # fall back to next action on failure (auto mode)
    min_observations_per_action=0,   # exploration floor — try each action N times first
    base_url="https://layerinfinite.me",
    timeout=10.0,
    max_retries=3,
    log_async=True,                  # non-blocking outcome logging (default)
)

Exploration Floor

If your LLM fallback always picks the same action, LI never sees the others. Set min_observations_per_action to force exploration:

li = Layerinfinite(
    api_key="...",
    agent_id="my-agent",
    mode="auto",
    min_observations_per_action=20,  # try every action at least 20 times
)

Manual Outcome Logging

For cases where you can't use the decorator:

from layerinfinite import Layerinfinite, LogOutcomeRequest

li = Layerinfinite(api_key="...", agent_id="my-agent")

li.log_outcome(LogOutcomeRequest(
    agent_id="my-agent",
    action_name="switch_provider",
    issue_type="payment_failed",
    success=True,
    # optional: if omitted, LI infers score from success/failure + soft signals
    outcome_score=0.82,
    business_outcome=li.normalize_business_outcome("ok"),  # -> "resolved"
))

Error Handling

from layerinfinite import Layerinfinite, LowConfidenceError
from layerinfinite.exceptions import LayerinfiniteAuthError, LayerinfiniteRateLimitError

li = Layerinfinite(api_key="...", agent_id="my-agent", mode="auto")

try:
    result = li.run("payment_failed")
except LowConfidenceError as e:
    # LI doesn't have enough confidence yet — handle manually
    print(e.confidence)         # 0.38
    print(e.threshold)          # 0.70
    print(e.suggestion.action_name)       # best candidate so far
    print(e.suggestion.outcomes_needed)   # how many more outcomes to log
except LayerinfiniteAuthError:
    print("Invalid API key")
except LayerinfiniteRateLimitError as e:
    print(f"Rate limited — retry after {e.retry_after}s")

Pending Outcomes Queue

If a network error occurs during _log_outcome, the SDK queues the outcome locally and replays it automatically on the next call. Queue location:

~/.layerinfinite/pending_outcomes.jsonl

Override with env var: LAYERINFINITE_PENDING_OUTCOMES_FILE

Fallback Endpoints

export LAYERINFINITE_BASE_URLS="https://fallback1.example.com,https://fallback2.example.com"

Context Manager

with Layerinfinite(api_key="...", agent_id="my-agent") as li:
    result = li.run("payment_failed")
