## 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 20
- Maintenance & community, 79 against 50

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

### Beam 1.0 (D)

Good for: An OpenAI-compatible endpoint for a large open-weight coding and agent model, for builders who want the same model hosted or self-hosted under Apache-2.0.

Ahead on:
- Schema & documentation, 84 against 55
- Agent ergonomics, 67 against 56
- Transparency & trust, 68 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: The API is a public beta with no SLA, and per-organisation rate limits and the daily allocation are not published as numbers

## 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.

**Beam 1.0.** The Reflection API is OpenAI-compatible, with an OpenAPI document, strict structured outputs and tool calls, and error codes that say when to retry, and the weights are Apache-2.0. It is a free public beta with unpublished daily limits and no per-token price, reasoning can't be turned off, and three API incidents were posted between 14 and 16 October 2026.

## 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

### Beam 1.0

1. Send `reasoning_effort` `low` or `medium` for short tasks. The default is `max`, and `none` or `minimal` return `400 unsupported_value`
2. Return every assistant message with its `reasoning_content` unchanged. If a turn comes back without it, start a new conversation, since later requests fail with `missing_required_parameter`
3. Don't rely on `stop` or `seed`. Both are accepted and ignored, so truncate output in your own code
4. Honour `x-should-retry: false` on a 429. It means a daily limit is spent and `Retry-After` counts to 00:00 UTC
5. Set `max_completion_tokens` yourself on long prompts. The default budget isn't reduced to fit the prompt and includes reasoning tokens
