unverified: neither the Web Unlocker guide nor the docs plan table says whether the Free plan can call Web Unlocker |
| Binding | request-rate 5 session creations a minute and 5 concurrent browsers on the free plan |
| Identity | email an account at signin.anchorbrowser.io, opened with an email address, Google or Microsoft; the first screen of the sign-up form has first name, last name (names not required) and email fields, and the page's configuration turns magic codes off and passwords on; whether the free plan asks for a card or a phone number after that screen is unverified: behind a sign-up |
| Egress | not applicable |
| Per-object cap | not applicable: the unit is a session |
| Retention | 7 days of data retention on the free plan (7 days) |
| Interface | rest REST sessions; raw HTML on the REST path and Markdown only over the browser control protocol |
| Tooling | a session model |
| Composes with | The Markdown-only-over-CDP split is why it is not a read leg: a plain POST returns HTML |
| Reliability | The keyless Agent Access route in the docs answers Agent Access is disabled on GET /v1/agent-access and GET /v1/agent-access/challenge, so a key needs a dashboard account |
| Notes | The docs price a task run at 0.1 credit (USD 0.10) and overage at USD 1.00 a credit, so the docs' USD 5 and the pricing card's 5 credits are one allowance. Agent Access, the documented keyless key route (1 credit with no identity, 5 with an OIDC token carrying a verified email), answers that it is disabled. |
| Evidence note | documented free tier, session limits and retention read on the vendor's pricing and docs pages |
