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 55

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

BlockRun.AI BB

Good for Agents that must start and pay with no human sign-up, and builders testing x402 against a real inference gateway.

Ahead on

  • Schema & documentation, 75 against 55
  • Agent ergonomics, 70 against 56
  • Security & auth, 70 against 45
  • Payments & pricing, 100 against 70
  • Maintenance & community, 85 against 79
  • Transparency & trust, 65 against 59

Also in its favour

  • Agent-ready, a grade of BB or better
  • An agent can pay per call over x402, with no account
  • Runs on your own machine
  • No incidents deducted, where Antseed loses 4 points for them

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.

BlockRun.AI

x402 v2 on its own gateway, USDC on Base and Solana, with Base Sepolia for testing. The status page shows live checks only and keeps no incident history.

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

BlockRun.AI

  1. Fund a dedicated wallet with a small USDC balance. The balance is the spending cap
  2. Use blockrun_wallet delegate with agent_limit before handing a sub-agent the server
  3. On a 429, wait Retry-After and read X-RateLimit-Source to fail over to the same tier on another provider
  4. Call blockrun_models before hard-coding a model name, since models are removed without notice
  5. Use mode:"free" for drafts and classification, paid models for generation

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.
