Official PHP SDK for the [Postpin](https://postpin.in) shipping-rate API — calculate courier charges between Indian pincodes, check serviceability, look up the pincode directory, and verify webhooks.

- **Zero Composer dependencies** — uses `ext-curl` and `ext-json` only.
- **Robust by default** — automatic retries with exponential backoff + jitter, `Retry-After` support, per-request timeouts, and idempotency keys.
- **Typed exceptions** — catch `RateLimitException`, `QuotaExceededException`, `ValidationException`, and friends.
- **Secure webhooks** — constant-time HMAC signature verification with replay protection.
- **Testable** — a `Transport` interface lets you inject a fake HTTP client.
