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.\n\n**OpenRouter.** Public OpenAPI document, llms.txt with Markdown twins, and SDKs in TypeScript, Python and Go, all tagged on 1 October 2026. No machine payment. USDC top-ups go to a prepaid balance.\n\n## Before you call either\n\n### Antseed\n\n1. Send a placeholder key such as `antseed-p2p`. The proxy forwards whatever `Authorization` or `x-api-key` header the client sends to the seller\n2. Call `GET /v1/models` first and request a concrete id. The `antseed` alias works only when the desktop app has a model selected\n3. Handle 402 `insufficient_deposits` by reading `suggestedAmount`, then fund the address from `antseed buyer deposit` with USDC on Base\n4. Pass `--verifiers antseed-verifier --require-verifier` to `antseed buyer start` when prompts are private, so only TEE-verified sellers are routed\n5. Read `x-antseed-peer-id` and `x-antseed-estimated-cost-usd` on each response, and pin a seller with `\u003cpeerId\u003e@\u003cmodel\u003e` when the same one must answer\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## Questions\n\n### Which is better for AI agents, Antseed or OpenRouter?\n\nOpenRouter scores 68.5 (B) on agent readiness against Antseed's 55.1 (C), and leads in 5 of 7 scored categories. Antseed leads on reliability and payments \u0026 pricing.\n\n### Do Antseed and OpenRouter need an API key?\n\nAntseed needs no key. OpenRouter needs an API key.\n\n### Can an agent call Antseed and OpenRouter without installing anything?\n\nNo hosted endpoint is listed for Antseed. OpenRouter has a hosted endpoint at https://openrouter.ai/api/v1.\n\n### Are Antseed and OpenRouter open source?\n\nAntseed is open source (GPL-3.0 (LICENSE in the repository). The @antseed/cli manifest on npm carries no licence field). No open-source release is listed for OpenRouter.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/antseed-vs-openrouter.json, and with the fewest tokens: https://www.anchorterminal.com/compare/antseed-vs-openrouter.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"antseed\", \"b\": \"openrouter\"}`.
