Which one, for what

Antseed C

Best 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 20
  • Maintenance & community, 79 against 46
  • Transparency & trust, 59 against 52

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

Meta Model API D

Best for Long-running agent and coding work over text, images, video, audio and PDFs with a 1M-token context, where training must stay off by default.

Ahead on

  • Schema & documentation, 60 against 55
  • Agent ergonomics, 75 against 56
  • Security & auth, 64 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

Muse Wonder is labelled a preview, and no deprecation policy or notice period was found

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.

Meta Model API

Meta Model API serves Muse Wonder, in preview since 12 October 2026, and Muse Spark with 1M-token context, constrained JSON Schema output, automatic prompt caching and per-token prices published without a login. Standard-mode content is not used for training. There's no free allowance, status history, OpenAPI file, deprecation policy or way to force a tool call.

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

Meta Model API

  1. Use muse-wonder-1.0 for long multi-step work and muse-spark-1.3 for cheaper, high-volume calls. Both take the same requests
  2. Keep personal or confidential data away from -contributor model IDs. Meta may train on that content
  3. Honour Retry-After on 429 and 503, which is 60 seconds for service_overloaded, and check GET https://api.meta.ai/v1/status, which needs no key
  4. Pass the key to the OpenAI SDK explicitly or set OPENAI_API_KEY. The SDK doesn't read MODEL_API_KEY
  5. Leave tool_choice at auto. The docs say none and required are not supported

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
