No published request rate limits, 429 handling or SLA.\n\n**Vast.ai.** API keys can be limited by permission category and by resource ID, the REST API has a public OpenAPI 3.1 file, and the CLI ships weekly with a skill file for coding agents. Machines belong to independent hosts, prices move with the market, rate-limit thresholds are unpublished, and there is no SLA or free tier.\n\n## Before you call either\n\n### Beam\n\n1. Check the response body for `ok: false` on gateway calls; a failure can arrive as HTTP 200\n2. Don't pipe `beam deploy --format json` output into CI logs, since it contains the workspace token\n3. Route anything over 180 seconds to a task queue and poll the task instead of holding the endpoint request\n4. Set `keep_warm_seconds` deliberately; the 180-second endpoint default bills three minutes of GPU after every call\n5. Pass `gpu=[\"RTX4090\", \"A10G\"]` so a job still schedules when one type is out\n\n### Vast.ai\n\n1. Create a scoped key with `vastai create api-key --permissions` for the agent. A default key has full account access, billing and key management included\n2. Pass `--raw` on every CLI command for JSON output, and `-y` on `vastai destroy instance`, which otherwise waits for a confirmation prompt\n3. Register an SSH key with `vastai create ssh-key` before creating an instance, or the host is unreachable\n4. Destroy instances when finished. A stopped instance still bills storage, and a zero balance without a saved card leads to deletion\n5. Back off on HTTP 429 yourself when calling REST directly. The CLI retries 429 three times from 0.15 seconds\n6. Filter searches with `verified=true` or the Secure Cloud option for sensitive data, and set a `dph_total` price cap\n\n## Questions\n\n### Which is better for AI agents, Beam or Vast.ai?\n\nVast.ai scores 62.6 (B) on agent readiness against Beam's 55.5 (C), and leads in 3 of 7 scored categories. Beam leads on payments \u0026 pricing and transparency \u0026 trust.\n\n### Can an agent call Beam and Vast.ai without installing anything?\n\nYes. Beam has a hosted endpoint at https://app.beam.cloud/api/v1 and Vast.ai at https://console.vast.ai/api/v0.\n\n### Are Beam and Vast.ai open source?\n\nBeam is open source (AGPL-3.0).
