Tokens, turns and time describe resource use, not a dollar price.
One of 19 test cases the skill fixed. Same model, same prompt, with and without the skill.
When broadcasting transactions directly to Base mainnet (EVM chain ID 8453), which asset is used natively to pay for transaction execution gas fees?
| Checked | Without skill | With skill |
|---|---|---|
| The response identifies ETH as the native asset used to pay transaction gas fees on Base mainnet. | Passed | Passed |
| The response clarifies that ERC-20 tokens like USDC cannot pay native L2 execution gas directly. | Missed | Passed |
The instructions your model reads when the skill loads.
Venice.ai is an OpenAI-compatible inference platform for text, image, audio, video, embeddings, and typed decisions. One API - two ways to pay: a traditional API key (Venice account), or a wallet (x402, USDC on Base or Solana, no account required).
api.venice.ai for the first time.x-ratelimit-*, PAYMENT-REQUIRED, deprecation headers, etc.).All endpoints live under:
https://api.venice.ai/api/v1
The OpenAPI spec is served at https://api.venice.ai/api/v1/swagger.yaml (info.version is a YYYYMMDD.HHMMSS timestamp; read it from the live spec).
| Scheme | Header | Best for |
|---|---|---|
BearerAuth | Authorization: Bearer $VENICE_API_KEY | Server-side apps, account management, usage analytics, DIEM / bundled credits |
siwx (x402) | SIGN-IN-WITH-X: <base64 SIWX JSON> (legacy X-Sign-In-With-X also accepted) | No account, pay-as-you-go with USDC on Base or Solana, serverless / agents |
Not every endpoint accepts both:
| Endpoints | Accepts |
|---|---|
All inference: chat, responses, embeddings, decisions, image, audio (speech, transcriptions, voices, queue/retrieve/complete, voice-changer queue/retrieve/complete), video queue/retrieve/complete, augment, POST /crypto/rpc/{network} | Bearer or SIWX |
/api_keys/* (except generate_web3_key), /billing/* (except the retired /billing/usage), /characters/* | Bearer only (a SIGN-IN-WITH-X header alone gets 401 Authentication failed) |
/x402/balance/{wallet}, /x402/transactions/{wallet} | SIWX only (signer must own the wallet) |
/models*, /image/styles, /video/quote (except upscale models such as topaz-video-upscale: Bearer key required, so wallets can't quote them), /audio/quote, /audio/voice-changer/quote, /crypto/rpc/networks, /tee/attestation, /tee/signature, /api_keys/generate_web3_key, POST /x402/top-up | No auth needed |
On any route that needs credentials - Bearer-only ones included - a request with no Authorization and no SIGN-IN-WITH-X header gets 402 with an x402 discovery body (payment options + SIWX challenge + authOptions), not 401. See venice-auth.
