chatads-sdk 0.1.9

Lightweight Python client for the ChatAds affiliate scoring API

ChatAds Python SDK

A tiny, dependency-light wrapper around the ChatAds /v1/chatads/messages endpoint. It mirrors the response payloads returned by the FastAPI service so you can drop it into CLIs, serverless functions, or orchestration tools.

Installation

pip install chatads-sdk

The package is published on PyPI. Install from source only if you're developing locally.

Quickstart

from chatads_sdk import ChatAdsClient, AsyncChatAdsClient, FunctionItemPayload

# Synchronous usage
with ChatAdsClient(
    api_key="YOUR_X_API_KEY",
    base_url="https://chatads--chatads-api-fastapiserver-serve.modal.run",
    raise_on_failure=True,
    max_retries=2,
    retry_backoff_factor=0.75,
) as client:
    payload = FunctionItemPayload(
        message="Looking for a CRM to close more deals",
        country="US",
    )
    result = client.analyze(payload)
    if result.success and result.data.filled:
        print(result.data.ad.product, result.data.ad.link)
    else:
        print("No match:", result.data.reason if result.data else "unknown")

# Async usage
async with AsyncChatAdsClient(
    api_key="YOUR_X_API_KEY",
    base_url="https://chatads--chatads-api-fastapiserver-serve.modal.run",
    max_retries=3,
) as async_client:
    result = await async_client.analyze_message(
        "Need data warehousing ideas",
        country="US",
        message_analysis="fast",
    )
    print(result.raw)

Request Options

The FunctionItemPayload supports these fields:

Field	Type	Description
message	str (required)	Message to analyze (1-5000 chars)
ip	str	IPv4 address for country detection (max 64 characters)
country	str	Country code (e.g., 'US'). If provided, skips IP-based country detection
message_analysis	str	Controls keyword extraction method. Use 'fast' to optimize for speed, 'thorough' (default) to optimize for best keyword selection
fill_priority	str	Controls affiliate link discovery. Use 'speed' to optimize for speed, 'coverage' (default) to ping multiple sources for the right affiliate link
min_intent	str	Minimum purchase intent level required for affiliate resolution. 'any' = no filtering, 'low' (default) = filter garbage, 'medium' = balanced quality/fill, 'high' = high-intent keywords only
skip_message_analysis	bool	Treat exact message as product keyword. When true, goes straight to affiliate link discovery without keyword extraction

Response Structure

result.success         # bool - True if request succeeded
result.data.matched    # bool - True if keywords were extracted
result.data.filled     # bool - True if affiliate URL was returned
result.data.ad         # ChatAdsAd or None
result.data.keyword    # Extracted keyword used for matching
result.data.reason     # Reason for no match (if applicable)
result.error           # ChatAdsError or None (code, message, details)
result.meta.request_id # Unique request identifier
result.meta.usage      # UsageInfo with quota information
result.raw             # Full raw JSON response

Error Handling

Non-2xx responses raise ChatAdsAPIError with:

• status_code - HTTP status code
• response.error.code - Error code (e.g., DAILY_QUOTA_EXCEEDED, RATE_LIMITED)
• response.error.message - Human-readable message
• retry_after - Seconds to wait (for 429 responses)

Set raise_on_failure=True to also raise on 200 responses with success=false.

Retryable status codes (automatic with max_retries>0):

• 408 Request Timeout
• 429 Rate Limited
• 500, 502, 503, 504 Server errors

Notes

• Retries are opt-in. Provide max_retries>0 to automatically retry transport errors and retryable status codes. The client honors Retry-After headers and falls back to exponential backoff.
• base_url must point to your HTTPS deployment (the client rejects plaintext URLs so API keys are never transmitted insecurely).
• The default hosted environment lives at https://chatads--chatads-api-fastapiserver-serve.modal.run; use your own domain if you're proxying ChatAds behind something else.
• FunctionItemPayload matches the server-side FunctionItem pydantic model. Keyword arguments passed to ChatAdsClient.analyze_message() accept either snake_case or camelCase keys.
• Reserved payload keys (e.g., message, pageUrl) cannot be overridden through extra_fields; doing so raises ValueError to prevent silent mutations.
• debug=True enables structured request/response logging, but payload contents are redacted automatically so you don't leak PII into logs.

CLI Smoke Test

For a super-quick check, either edit the config block at the top of run_sdk_smoke.py or set:

export CHATADS_API_KEY="..."
export CHATADS_BASE_URL="https://chatads--chatads-api-fastapiserver-serve.modal.run"
export CHATADS_MESSAGE="Looking for ergonomic office chairs"
# Optional extras
export CHATADS_IP="1.2.3.4"
export CHATADS_COUNTRY="US"

Then run:

python run_sdk_smoke.py

It prints the raw JSON response or surfaces a ChatAdsAPIError with status/error fields so you can see exactly what the API returned.
