Build the service layer for all pet-related API calls to the PetChain NestJS backend.

[llinsss]

Context

This is a React Native mobile app written in TypeScript. The "backend" folder contains issues — actual implementation goes in src/. This is client-side code, not server-side.

File to Create

src/services/petService.ts

Requirements

• getAllPets() — fetch all pets for the logged-in owner
• getPetById(petId) — fetch a single pet by ID
• getPetByQRCode(qrCode) — fetch pet using scanned QR code
• createPet(data) — register a new pet
• updatePet(petId, data) — update pet details
• deletePet(petId) — remove a pet

Acceptance Criteria

• All CRUD functions are implemented and typed
• getPetByQRCode() works with QR scan data
• Errors from the API are handled and surfaced correctly
• All functions return typed Promise responses
• Uses the shared API client (not a raw Axios call)

Tech Stack

• TypeScript
• Axios

@chiemezie1 has applied to work on this issue as part of the Stellar Wave Program's 3rd wave.

Hi, I'd like to work on issue #63.

I'll create src/services/petService.ts implementing all six typed functions — getAllPets, getPetById, getPetByQRCode, createPet, updatePet, and deletePet — using the shared API client from #1 and the Pet model types from #3. All functions will return typed Promise responses, handle API errors and surface them correctly, and getPetByQRCode will accept QR scan data directly from the scanner output.

Can I be assigned?
