The free edition has one unscoped API key and no audit logs, and Lago's llms.txt understates what its MCP server can change.\n\n**Skyfire API + MCP.** Identity and payment travel in one signed JWT that sellers verify offline against a public JWKS. No x402 or MPP; both buyer and seller must be on Skyfire.\n\n## Before you call either\n\n### Lago\n\n1. Call `\u003cyour Lago API origin\u003e/api/v1` with `Authorization: Bearer \u003ckey\u003e`. On Lago Cloud the hosts are `api.getlago.com` and `api.eu.getlago.com`\n2. Send every usage event with a deterministic `transaction_id` and an explicit `timestamp`, and resend the same payload on retry. On the ClickHouse event store a changed timestamp is billed again\n3. Expect 422 `value_already_exist` for a repeated event on the Postgres event store. Treat it as success for a retry\n4. Page with `page` and `per_page` and read `meta.next_page` and `meta.total_count`. The default page size is 100 in most cases\n5. Treat the free edition's API key as full access. It can void invoices and terminate subscriptions, so keep it out of prompts and ask a person before financial changes\n6. Before giving an assistant the MCP server, note that it includes `delete_invoice`, `void_invoice`, `delete_plan` and `create_payment` and sets no read-only annotations\n\n### Skyfire API + MCP\n\n1. Buyer keys create tokens and seller keys charge them; a 403 usually means the wrong key type\n2. Set the token amount to the most the task should spend; the seller can't charge more\n3. Use a kya token when a site only needs to know who you are; it can't be charged\n4. Don't retry `FORBIDDEN` or `NOT_ELIGIBLE`; fix the key or wait for approval first\n5. Rehearse against mcp-sandbox.skyfire.xyz before using mcp.skyfire.xyz\n\n## Questions\n\n### Which is better for AI agents, Lago or Skyfire API + MCP?\n\nLago scores 65.7 (B) on agent readiness against Skyfire API + MCP's 40.3 (E), and leads in 6 of 7 scored categories.\n\n### Do Lago and Skyfire API + MCP need an API key?\n\nBoth need an API key.\n\n### Can an agent call Lago and Skyfire API + MCP without installing anything?\n\nNo hosted endpoint is listed for Lago.
