No OpenAPI document or pagination was found in the reviewed documentation, and the Free plan keeps audit logs for 24 hours.\n\n**Pulumi ESC.** An agent can start without a signup, because the Pulumi CLI creates a free ephemeral account that includes ESC, and the REST API has a public OpenAPI document. Audit logs, custom roles and approvals need the Pro edition at $400 a month, and no API rate limit was found in the reviewed documentation.\n\n## Before you call either\n\n### Phase\n\n1. Enable server-side encryption on the app before calling `/v1/secrets`. Without it the REST API cannot read or write that app's secrets\n2. Send `Authorization: Bearer ServiceAccount \u003ctoken\u003e` for a service account and `Bearer User \u003ctoken\u003e` for a personal access token. The token type is part of the header\n3. Stay under 120 requests a minute per account on Free and 240 on Pro, and wait the seconds in the `retry-after` header on a 429\n4. Treat a 409 on `POST /v1/secrets` as the key already existing at that path, and use `PUT` to change it. Rotating secrets reject `PUT` and `DELETE`\n5. Have a person run `phase ai enable` and choose masked values. The CLI blocks an agent from running `phase ai enable` or `phase ai disable` itself\n\n### Pulumi ESC\n\n1. Use `pulumi env`, not `esc`. The standalone CLI stopped at v0.26.0 and gets no security fixes\n2. Read one value with `pulumi env open \u003corg\u003e/\u003cproject\u003e/\u003cenv\u003e \u003cproperty path\u003e` so the whole environment doesn't enter context\n3. Run tools with `pulumi env run \u003cenv\u003e -- \u003ccmd\u003e`, which filters secret values from the command's output unless -i is set\n4. Set PULUMI_ACCESS_TOKEN for the SDKs. From 0.14.0 they no longer read the CLI login on disk\n5. Send `Authorization: token \u003ctoken\u003e` and `Accept: application/vnd.pulumi+8` on REST calls, and expect 409 when an environment changed since it was read\n6. Relay the claim link an agent account prints. The account goes read-only after 72 hours and locks after 30 days unclaimed\n\n## Questions\n\n### Which is better for AI agents, Phase or Pulumi ESC?\n\nPulumi ESC scores 71.1 (BB) on agent readiness against Phase's 68 (B), and leads in 3 of 7 scored categories. Phase leads on reliability and transparency \u0026 trust.\n\n### Do Phase and Pulumi ESC need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Phase and Pulumi ESC without installing anything?\n\nYes. Phase has a hosted endpoint at https://api.phase.dev and Pulumi ESC at https://api.pulumi.com.\n\n### Are Phase and Pulumi ESC open source?\n\nPhase is open source (MIT outside the `ee/` directories, which are under the proprietary Phase Console Enterprise licence).
