No machine payment. USDC top-ups go to a prepaid balance.\n\n**Prism Inference.** Three wire formats, a public OpenAPI 3.1 file, per-token prices in a keyless catalogue and zero data retention by default on every tier. The service launched on 24 September 2026 with two models, one of them by request, from a two-person company. No rate-limit numbers, SLA document, free tier or deprecation policy was found.\n\n## Before you call either\n\n### OpenRouter\n\n1. Set `provider.data_collection: \"deny\"` or `provider.zdr: true` when the prompt holds anything private\n2. Pass a `models` list so a failed provider falls through to the next one\n3. Honour `Retry-After` on 429 and 503, and check the stream body for errors even on a 200\n4. Set `max_price` so a routed request can't land on an expensive provider\n5. Free models allow 50 requests a day until $10 of credit has been bought. Check `GET /api/v1/key` for what's left\n\n### Prism Inference\n\n1. Call `GET https://api.prisminference.com/v1/models` at start-up, with no key, and use only ids it returns. Expect 403 on `gemma-4-31b` without organisation access\n2. Use base URL `https://api.prisminference.com/v1` for OpenAI clients and `https://api.prisminference.com` with no `/v1` for Anthropic clients\n3. Read `error.retryable` before retrying, and wait for `Retry-After` on 429, which covers both key limits and model capacity\n4. Send `reasoning_effort: \"none\"` or `low` when latency matters. Reasoning is on by default and its tokens are billed as output\n5. Keep conversation state yourself and send `store: false` on Responses. `previous_response_id`, stored responses and hosted tools aren't supported\n\n## Questions\n\n### Which is better for AI agents, OpenRouter or Prism Inference?\n\nOpenRouter scores 68.5 (B) on agent readiness against Prism Inference's 60.1 (C), and leads in 5 of 7 scored categories. Prism Inference leads on reliability and security \u0026 auth.\n\n### Do OpenRouter and Prism Inference need an API key?\n\nBoth need an API key.\n\n### Can an agent call OpenRouter and Prism Inference without installing anything?\n\nYes.
