# Storage: Upload

Upload a local file via multipart/form-data and receive a permanent public URL. TTL tier (1 / 7 / 30 / 90 / 365 days, default 30) drives both price ($0.001–$0.01 USDC) and storage lifetime. Body is validated pre-charge — invalid bodies return 400 without settling. Files are publicly accessible to anyone holding the returned URL — URLs are unguessable but not secret. Do not upload secrets, credentials, PII, or private business data.

- Method: POST
- Path: `/upload`
- Price: $0.00100000
- Content-Type: multipart/form-data

## How to invoke

Payment is handled automatically — the client signs the 402 challenge and retries.

### TypeScript — Tempo (mppx + fetch) ([docs](https://mpp.dev/sdk/typescript/client))

```ts
import { privateKeyToAccount } from 'viem/accounts'
import { Mppx, tempo } from 'mppx/client'

Mppx.create({
  methods: [tempo({ account: privateKeyToAccount('0x...') })],
})

const form = new FormData()
form.append('file', /* File from <input> or Blob */, 'file.bin')
form.append('ttl_days', '1')

const res = await fetch('https://storage.payweave.services/upload', {
  method: 'POST',
  body: form,
})
const data = await res.json()

Mppx.create({ methods: [solana({ signer })] })

const form = new FormData()
form.append('file', /* File from <input> or Blob */, 'file.bin')
