Which one, for what

Antseed C

Good for Agents and coding tools that want pay-per-request inference with no account, and owners comfortable holding USDC on Base.

Ahead on

  • Reliability, 62 against 28
  • Payments & pricing, 70 against 35
  • Maintenance & community, 79 against 62

Also in its favour

  • No key needed to call it
  • Free to start without a card
  • Open source

Watch for

The buyer proxy copies a client's Authorization and x-api-key headers to the seller. The repository's March 2026 review flagged it and issue #1104 is open

Novita AI D

Good for Agents that want many open-weight models at per-token prices behind one OpenAI-style key, with keys that can be limited by model, IP and expiry.

Ahead on

  • Schema & documentation, 62 against 55
  • Agent ergonomics, 72 against 56
  • Security & auth, 65 against 45

Also in its favour

  • A hosted endpoint, with nothing to install
  • No incidents deducted, where Antseed loses 4 points for them

Watch for

No status page or SLA was found on the home page, the docs index or the docs site map. The home page states 99.5% uptime with no supporting document

Verdicts

Antseed

A buyer needs no account. The CLI creates a wallet key, free models answer at once and paid ones draw on deposited USDC, with seller, tokens and cost returned in response headers. Sellers are unvetted and can read prompts unless TEE-verified, the proxy forwards a client's own credential headers to them, and every package is pre-1.0.

Novita AI

Per-token prices for about 140 language models are public, and each key can carry an expiry, a model allowlist and a source IP allowlist. No status page, SLA or security.txt was found, the per-model rate limit figures are drawn by script, and both vendor SDK repositories are archived while the docs still point to them.

Before you call either

Antseed

  1. Send a placeholder key such as antseed-p2p. The proxy forwards whatever Authorization or x-api-key header the client sends to the seller
  2. Call GET /v1/models first and request a concrete id. The antseed alias works only when the desktop app has a model selected
  3. Handle 402 insufficient_deposits by reading suggestedAmount, then fund the address from antseed buyer deposit with USDC on Base
  4. Pass --verifiers antseed-verifier --require-verifier to antseed buyer start when prompts are private, so only TEE-verified sellers are routed
  5. Read x-antseed-peer-id and x-antseed-estimated-cost-usd on each response, and pin a seller with <peerId>@<model> when the same one must answer

Novita AI

  1. Set the OpenAI client base URL to https://api.novita.ai/openai and send the key as Authorization: Bearer. Keys start with sk_
  2. Do not close a connection to stop generation. A request that reached the model is billed in full under status 499, so cap output with max_tokens
  3. On 429, check whether the code is RATE_LIMIT_EXCEEDED or TOKEN_LIMIT_EXCEEDED and back off exponentially. No Retry-After header is documented
  4. Read the changelog for retirement notices before pinning a model id. One retirement in October 2026 came with 11 days' notice
  5. Ask the account owner for a key with an expiry, a model access policy and an IP allowlist. Keys are created and deleted only in the console
