POST /x402/top-up without headers to get payment requirements 2. Choose one of the returned Base or Solana payment options and sign a USDC payment using the x402 SDK 3. POST /x402/top-up with PAYMENT-SIGNATURE header to add credits 4. Call any inference endpoint with SIGN-IN-WITH-X header **Pricing:** Prepaid credits consumed per request. Check /models for available models and their capabilities. servers: - url: https://api.venice.ai/api/v1 security: - BearerAuth: [] tags: - description: >- Generate speech/audio, transcribe audio, and manage asynchronous audio generation jobs. name: Audio - description: >- Given a list of messages comprising a conversation, the model will return a response.

Billed per credit. name: Crypto RPC - description: >- Wallet-based API access using the x402 protocol. No API key required — authenticate with an EVM or Solana wallet. **How it works:** 1. **Authenticate** — Send a `SIGN-IN-WITH-X` header (base64-encoded signed SIWX payload) with any request. EVM wallets sign an EIP-4361 SIWE message; Solana wallets sign the Solana SIWX message with Ed25519. See the `siwx` security scheme for the exact format. 2. **Top up** — `POST /x402/top-up` without a payment header returns an `accepts` array with Base and Solana USDC payment options. Choose one entry, sign it using the x402 SDK (`npm install x402`), and re-submit with the `PAYMENT-SIGNATURE` header (the legacy `X-402-Payment` and `X-PAYMENT` names are also accepted). 3. **Use any endpoint** — All inference endpoints (chat, image, audio, video, embeddings) accept `siwx` as an alternative to `BearerAuth`. Charges are deducted from your USDC credit balance. 4. **Monitor balance** — `GET /x402/balance/{walletAddress}` returns your current balance. The `X-Balance-Remaining` response header on inference calls also reports it. **Quick start (5 lines):** ``` import { VeniceClient } from '@venice-ai/x402-client' const venice = new VeniceClient(process.env.WALLET_KEY) await venice.topUp(10) // $10 USDC on a supported x402 rail const res = await venice.chat({ model: 'zai-org-glm-5-1', messages: [{ role: 'user', content: 'Hello!' }] }) ``` **Payment:** USDC on Base (chain ID 8453) or Solana mainnet. Minimum top-up: $5. Alternatively, stake DIEM tokens for daily credits (1 DIEM = $1/day). name: x402 externalDocs: description: Venice.ai API documentation url: https://docs.venice.ai paths: /api_keys/{id}: get: tags: - API Keys summary: Get API key details by ID description: >- Return details about a specific API key, including rate limits and balance data. operationId: getApiKeyById parameters: - name: id in: path required: true schema: type: string description: The ID of the API key to retrieve responses: '200': description: OK content: application/json: schema: type: object properties: data: type: object properties: apiKeyType: type: string enum: - INFERENCE - ADMIN description: API Key type example: ADMIN consumptionLimits: type: object properties: usd: anyOf: - type: number minimum: 0 maximum: 9999999999 - nullable: true title: 'null' - nullable: true title: 'null' description: USD limit example: 50 diem: anyOf: - type: number minimum: 0 maximum: 9999999999 - nullable: true title: 'null' - nullable: true title: 'null' description: Diem limit example: 10 vcu: anyOf: - type: number minimum: 0 maximum: 9999999999 - nullable: true title: 'null' - nullable: true title: 'null' description: VCU limit (deprecated - use Diem instead) deprecated: true example: 100 description: >- The API Key consumption limits, evaluated against the window selected by `limitPeriod`. example: usd: 50 diem: 10 vcu: 30 limitPeriod: type: string enum: - EPOCH - MONTH - LIFETIME description: >- Reset window the consumption limits apply to. `EPOCH` resets every UTC day (legacy default). `MONTH` resets on the 1st of each UTC calendar month. `LIFETIME` never resets, so the limit acts as a permanent cap on the key. example: MONTH createdAt: type: string nullable: true description: API Key creation date example: '2023-10-01T12:00:00.000Z' description: type: string description: API Key description example: Example API Key expiresAt: type: string nullable: true description: API Key expiration date example: '2023-10-01T12:00:00.000Z' id: type: string description: API Key ID example: e28e82dc-9df2-4b47-b726-d0a222ef2ab5 last6Chars: type: string description: Last 6 characters of the API Key example: 2V2jNW lastUsedAt: type: string nullable: true description: API Key last used date example: '2023-10-01T12:00:00.000Z' usage: type: object properties: trailingSevenDays: type: object properties: usd: type: string description: USD usage in the trailing 7 days example: '10.2424' vcu: type: string description: >- VCU usage in the trailing 7 days (deprecated - use Diem instead) deprecated: true example: '42.2315' diem: type: string description: Diem usage in the trailing 7 days example: '4.2231' required: - usd - vcu - diem required: - trailingSevenDays currentPeriodUsage: type: object properties: usd: type: string description: USD usage in the current limit period example: '5.1234' diem: type: string description: Diem usage in the current limit period example: '2.5000' required: - usd - diem description: >- Usage within the current limit period window.
