Pine Labs Online P3P Client SDK — x402 Pine Labs Online P3P client for AI agents (Python)

Pine Labs Online P3P Client SDK (Python)

Python SDK for Pine Labs Online P3P client integrations. It mirrors p3p-client-sdk, intercepts HTTP 402 Payment Required responses, creates customer-scoped P3P payment credentials, and retries paid requests.

Installation

pip install pinelabs-online-p3p-client-sdk

Import module: pinelabs_p3p_client. Requires Python 3.9 or newer.

Quick Start

from pinelabs_p3p_client import (
    ClientRuntimeContext,
    P3PEnvironment,
    PaymentMethod,
    PineLabsOnlineClient,
    PineLabsOnlineClientConfig,
)

client = PineLabsOnlineClient.create(PineLabsOnlineClientConfig(
    env=P3PEnvironment.SANDBOX,
    selectedPaymentMethod=PaymentMethod.RESERVE_PAY,
    clientId="client-client-id",
    clientSecret="client-client-secret",
))

response = client.get(
    "https://server.example.com/api/premium",
    context=ClientRuntimeContext(
        customerReference="9876543210",
        mobileNumber="9876543210",
    ),
)
print(response.json())
client.close()

Customer identity is runtime context, not static SDK config. This lets one client instance safely serve many customers.

By default, the SDK uses client-credentials customer auth: it exchanges clientId and clientSecret through POST /api/auth/v1/token, then calls POST /mpp/v1/token.

For customer API-token flows, explicitly set customerAuthMode=P3PCustomerAuthMode.CustomerKey and pass customerKey plus mobileNumber in ClientRuntimeContext.

Keep the client SDK instance long-lived in production. Auth tokens are cached per SDK instance.

402 Flow

1. Your code calls client.get(url, context=...).
2. The server returns HTTP 402 with WWW-Authenticate: Payment <challenge>.
3. The SDK decodes the challenge and validates amount, expiry, and accepted payment methods.
4. The SDK creates a token:
   • default mode: POST /mpp/v1/token with Authorization: Bearer <token>
   • customer-key mode: POST /api/v1/customer/mpp/token with Authorization: Bearer <token> and X-Customer-Key
   • customer.merchant_customer_reference and/or customer.mobile_number
   • challenge_id
   • payment_amount.value in minor units
5. The SDK retries the server with P3P-Credential: Payment <credential>.
6. The server captures the payment and may return Payment-Receipt.

Direct Token API

from pinelabs_p3p_client import Amount, CreateTokenOptions, PaymentMethod

token = client.methods.create_token(CreateTokenOptions(
    customerReference="9876543210",
    mobileNumber="9876543210",
    challengeId="ch_...",
    paymentAmount=Amount(value=50000, currency="INR"),
    paymentMethod=PaymentMethod.RESERVE_PAY,
))

The client SDK no longer creates mandates. Mandate/pre-authorization creation is handled by the server SDK.

Customer-key mode remains available:

from pinelabs_p3p_client import P3PCustomerAuthMode

customer_key_client = PineLabsOnlineClient.create(PineLabsOnlineClientConfig(
    env=P3PEnvironment.SANDBOX,
    selectedPaymentMethod=PaymentMethod.RESERVE_PAY,
    customerAuthMode=P3PCustomerAuthMode.CustomerKey,
    clientId="client-client-id",
    clientSecret="client-client-secret",
))

Timeout and retry settings (requestTimeoutMs, maxRetries, initialRetryDelayMs) apply to internal P3P calls only. The protected resource request itself uses the integrator's own HTTP timeout policy.

Environment defaults:

Env	URL	Timeout	Retries	Initial retry delay
P3PEnvironment.SANDBOX	https://pluraluat.v2.pinepg.in	60000 ms	3	500 ms
P3PEnvironment.PRODUCTION	https://api.pluralpay.in	45000 ms	3	500 ms

Supported Methods

• PaymentMethod.RESERVE_PAY -> "RESERVE_PAY" / UPI ReservePay
• PaymentMethod.OTM -> "OTM"
• PaymentMethod.Crypto -> "CRYPTO"

Error Handling

from pinelabs_p3p_client import P3PChallengeError, P3PError, P3PNetworkError

try:
    response = client.get(url, context=runtime_context)
except P3PChallengeError as err:
    ...
except P3PNetworkError as err:
    ...
except P3PError as err:
    print(err.code, err.http_status, err.details)
