## Which one, for what

### 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:
- Reliability, 55 against 40
- Schema & documentation, 75 against 60
- Security & auth, 70 against 64
- Payments & pricing, 100 against 20
- Maintenance & community, 85 against 46
- Transparency & trust, 65 against 52

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

Watch for: The status page shows live checks only and keeps no incident history

### Meta Model API (D)

Good 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:
- Agent ergonomics, 75 against 70

Also in its favour:
- A hosted endpoint, with nothing to install

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

## Verdicts

**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.

**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

### 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

### 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

## Questions

### Which is better for AI agents, BlockRun.AI or Meta Model API?

BlockRun.AI scores 72.4 (BB) on agent readiness against Meta Model API's 52.2 (D), and leads in 6 of 7 scored categories. Meta Model API leads on agent ergonomics.

### Do BlockRun.AI and Meta Model API need an API key?

BlockRun.AI takes an API key or an OAuth sign-in. Meta Model API needs an API key. An agent can also pay BlockRun.AI per call over x402, with no account.

### Can an agent call BlockRun.AI and Meta Model API without installing anything?

BlockRun.AI runs on your own machine, with no hosted endpoint listed. Meta Model API has a hosted endpoint at https://api.meta.ai/v1.
