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 40
  • Payments & pricing, 70 against 40

Also in its favour

  • No key needed to call it
  • 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

Gemini Developer API B

Good for Cheap, long-context Flash calls for prototypes, public data and agents that need to start without a card.

Ahead on

  • Schema & documentation, 85 against 55
  • Agent ergonomics, 90 against 56
  • Security & auth, 60 against 45
  • Transparency & trust, 72 against 59

Also in its favour

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

Watch for

Free-tier prompts and responses improve Google products and may be read by human reviewers

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.

Gemini Developer API

Free tier on 3.8 Flash and Flash-Lite with no billing account. Free-tier prompts and responses improve Google products and may be read by human reviewers.

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

Gemini Developer API

  1. Never send customer data through a free-tier key. Link billing first
  2. Don't request Gemini 4 Argon here. It has no Developer API model ID as of 5 October 2026
  3. Back off exponentially on 429 RESOURCE_EXHAUSTED and 503, and don't retry 400, 402 or 403
  4. Stop sending temperature, top_p and top_k. They've been deprecated since 2026-07-21
  5. Validate structured output yourself. The docs don't promise schema-constrained decoding
