There is no status page, no published rate limit and no public changelog, and the site's compliance claims contradict each other.\n\n**SPEV.** SPEV answers typed questions over text, audio or an image in one call, with a public OpenAPI schema and Apache-2.0 weights on Hugging Face. It is a day old, has an 8,192-token context, no status page or changelog, and Sprag's terms let it train on API content unless the customer opts out by email.\n\n## Before you call either\n\n### ScaleDown\n\n1. Send several questions about one item in one `/v1/scaledown` call. Each becomes its own Classify call and the usage is summed\n2. Pin `classify-1`, `extract-1` or `summarize-1` once you've tuned thresholds on your own labelled cases\n3. Set `context_chars` to 0 and use `top_n` on Extract unless you need the 500 characters of context each side\n4. Set `reasoning: false` on /classify when you only need the label. The reasoning call bills its input at 2x\n5. Back off and retry on 429, 502 and 504. No limits are published and calls have no side effects\n\n### SPEV\n\n1. Send `model: \"spev\"` to `POST https://api.sprag.ai/v1/decisions` with a bearer key. `/v1/systemone` returns 410\n2. Ask every question about one piece of evidence in one request. Answers come back in question order\n3. Send audio as base64 in `input_audio` with `format`, not as a data URL, and at most one image across all messages\n4. Keep evidence and questions under 8,192 tokens. Over the limit returns 400 `model_limit_exceeded`\n5. Back off on 429 and 503 for `Retry-After` seconds. Limits are 60 requests a minute per organisation by default\n6. Handle an answer of type `refusal`, which carries no probabilities\n\n## Questions\n\n### Which is better for AI agents, ScaleDown or SPEV?\n\nSPEV scores 51.1 (D) on agent readiness against ScaleDown's 48.6 (D), and leads in 2 of 7 scored categories. ScaleDown leads on security \u0026 auth, payments \u0026 pricing and maintenance \u0026 community.\n\n### Do ScaleDown and SPEV need an API key?\n\nBoth need an API key.\n\n### Can an agent call ScaleDown and SPEV without installing anything?\n\nYes. ScaleDown has a hosted endpoint at https://api.scaledown.xyz and SPEV at https://api.sprag.ai/v1/decisions.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/scaledown-vs-sprag-spev.json, and with the fewest tokens: https://www.anchorterminal.com/compare/scaledown-vs-sprag-spev.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"scaledown\", \"b\": \"sprag-spev\"}`.
