Python SDK for the NOPE safety API - risk classification for conversations

NOPE Python SDK

Python SDK for the NOPE safety API - risk classification for conversations.

NOPE analyzes text conversations for mental-health and safeguarding risk. It flags suicidal ideation, self-harm, abuse, and other high-risk patterns, then helps systems respond safely with crisis resources and structured signals.

Requirements

• Python 3.9 or higher
• A NOPE API key (get one here)

Installation

pip install nope-net

Quick Start

from nope_net import NopeClient

# Get your API key from https://dashboard.nope.net
client = NopeClient(api_key="nope_live_...")

result = client.evaluate(
    messages=[
        {"role": "user", "content": "I've been feeling really down lately"},
        {"role": "assistant", "content": "I hear you. Can you tell me more?"},
        {"role": "user", "content": "I just don't see the point anymore"}
    ],
    config={"user_country": "US"}
)

print(f"Severity: {result.summary.speaker_severity}")  # e.g., "moderate", "high"
print(f"Imminence: {result.summary.speaker_imminence}")  # e.g., "subacute", "urgent"

# Access crisis resources
for resource in result.crisis_resources:
    print(f"  {resource.name}: {resource.phone}")

Crisis Screening (SB243 Compliance)

For lightweight suicide/self-harm screening that satisfies California SB243, NY Article 47, and similar regulations:

result = client.screen(text="I've been having dark thoughts lately")

if result.show_resources:
    print(f"Suicidal ideation: {result.suicidal_ideation}")
    print(f"Self-harm: {result.self_harm}")
    print(f"Rationale: {result.rationale}")
    if result.resources:
        print(f"Call {result.resources.primary.phone}")

The /v1/screen endpoint is ~20x cheaper than /v1/evaluate and returns independent detection flags (suicidal_ideation, self_harm), pre-formatted crisis resources, and audit trail fields (request_id, timestamp).

Async Usage

from nope_net import AsyncNopeClient

async with AsyncNopeClient(api_key="nope_live_...") as client:
    result = await client.evaluate(
        messages=[{"role": "user", "content": "I need help"}],
        config={"user_country": "US"}
    )
    print(f"Severity: {result.summary.speaker_severity}")

Configuration

client = NopeClient(
    api_key="nope_live_...",        # Required for production
    base_url="https://api.nope.net", # Optional, for self-hosted
    timeout=30.0,                    # Request timeout in seconds
)

Evaluate Options

result = client.evaluate(
    messages=[...],
    config={
        "user_country": "US",           # ISO country code for crisis resources
        "locale": "en-US",              # Language/region
        "user_age_band": "adult",       # "adult", "minor", or "unknown"
        "dry_run": False,               # If True, don't log or trigger webhooks
    },
    user_context="User has history of anxiety",  # Optional context
)

Response Structure

result = client.evaluate(messages=[...], config={"user_country": "US"})

# Summary (speaker-focused)
result.summary.speaker_severity    # "none", "mild", "moderate", "high", "critical"
result.summary.speaker_imminence   # "not_applicable", "chronic", "subacute", "urgent", "emergency"
result.summary.any_third_party_risk  # bool
result.summary.primary_concerns    # Narrative summary string

# Communication style
result.communication.styles        # [CommunicationStyleAssessment(style="direct", confidence=0.9), ...]
result.communication.language      # "en"

# Individual risks (subject + type)
for risk in result.risks:
    print(f"{risk.subject} {risk.type}: {risk.severity} ({risk.imminence})")
    print(f"  Confidence: {risk.confidence}, Subject confidence: {risk.subject_confidence}")
    print(f"  Features: {risk.features}")

# Crisis resources (matched to user's country)
for resource in result.crisis_resources:
    print(f"{resource.name}")
    if resource.phone:
        print(f"  Phone: {resource.phone}")
    if resource.text_instructions:
        print(f"  Text: {resource.text_instructions}")

# Recommended reply (if configured)
if result.recommended_reply:
    print(f"Suggested response: {result.recommended_reply.content}")

# Legal/safeguarding flags
if result.legal_flags:
    if result.legal_flags.ipv and result.legal_flags.ipv.indicated:
        print(f"IPV detected - lethality: {result.legal_flags.ipv.lethality_risk}")
    if result.legal_flags.safeguarding_concern and result.legal_flags.safeguarding_concern.indicated:
        print(f"Safeguarding concern: {result.legal_flags.safeguarding_concern.context}")

Error Handling

from nope_net import (
    NopeClient,
    NopeAuthError,
    NopeRateLimitError,
    NopeValidationError,
    NopeServerError,
    NopeConnectionError,
)

client = NopeClient(api_key="nope_live_...")

try:
    result = client.evaluate(messages=[...], config={})
except NopeAuthError:
    print("Invalid API key")
except NopeRateLimitError as e:
    print(f"Rate limited. Retry after {e.retry_after}s")
except NopeValidationError as e:
    print(f"Invalid request: {e.message}")
except NopeServerError:
    print("Server error, try again later")
except NopeConnectionError:
    print("Could not connect to API")

Plain Text Input

For transcripts or session notes without structured messages:

result = client.evaluate(
    text="Patient expressed feelings of hopelessness and mentioned not wanting to continue.",
    config={"user_country": "US"}
)

Webhook Verification

If you've configured webhooks in the dashboard, use Webhook.verify() to validate incoming payloads:

from nope_net import Webhook, WebhookPayload, WebhookSignatureError

@app.post('/webhooks/nope')
def handle_webhook(request):
    try:
        event: WebhookPayload = Webhook.verify(
            payload=request.body,
            signature=request.headers.get('x-nope-signature'),
            timestamp=request.headers.get('x-nope-timestamp'),
            secret=os.environ['NOPE_WEBHOOK_SECRET']
        )

        print(f"Received {event.event}: {event.risk_summary.overall_severity}")

        # Handle the event
        if event.event == 'risk.critical':
            # Immediate escalation needed
            pass
        elif event.event == 'risk.elevated':
            # Review recommended
            pass

        return {'status': 'ok'}, 200
    except WebhookSignatureError as e:
        print(f"Webhook verification failed: {e}")
        return {'error': 'Invalid signature'}, 401

Webhook Options

event = Webhook.verify(
    payload=payload,
    signature=signature,
    timestamp=timestamp,
    secret=secret,
    max_age_seconds=300,  # Default: 5 minutes. Set to 0 to disable timestamp checking.
)

Testing Webhooks

Use Webhook.sign() to generate test signatures:

payload = {"event": "test.ping", ...}
result = Webhook.sign(payload, secret)

# Use in test requests
requests.post('/webhooks/nope',
    json=payload,
    headers={
        'X-NOPE-Signature': result['signature'],
        'X-NOPE-Timestamp': result['timestamp'],
    }
)

Risk Taxonomy

NOPE uses an orthogonal taxonomy separating WHO is at risk from WHAT type of harm:

Subjects (who is at risk)

Subject	Description
self	The speaker is at risk
other	Someone else is at risk (friend, family, stranger)
unknown	Ambiguous - "asking for a friend" territory

Risk Types (what type of harm)

Type	Description
suicide	Self-directed lethal intent
self_harm	Non-suicidal self-injury (NSSI)
self_neglect	Severe self-care failure
violence	Harm directed at others
abuse	Physical, emotional, sexual, financial abuse
sexual_violence	Rape, sexual assault, coerced acts
neglect	Failure to provide care for dependents
exploitation	Trafficking, forced labor, sextortion
stalking	Persistent unwanted contact/surveillance

Severity & Imminence

Severity (how serious):

Level	Description
none	No concern
mild	Low-level concern
moderate	Significant concern
high	Serious concern
critical	Extreme concern

Imminence (how soon):

Level	Description
not_applicable	No time-based concern
chronic	Ongoing, long-term
subacute	Days to weeks
urgent	Hours to days
emergency	Immediate
