- evidence:
  - [1] 2026-10-02: 
  - [1] 2026-10-22: the pricing page was read on 2026-10-22 and its worked example bills '10574 sessions × (38 min ÷ 60) × $0.09/hour', plus $8.00 a GB of proxy traffic and $0.01 a step; it publishes no free tier
  - [1] 2026-10-30: the Free plan includes 5 credits a month, up to 5 concurrent browsers and up to 500 browser sessions | capture: sha256:94f515a5affd7f171d70f6530aa764b6017abb4f3f4d484a85238706c61ff462 | quote: Free - 5 credits per month - 0.1 credits per completed task - Up to 5 concurrent browsers - Up to 500 browser sessions
  - [2] 2026-10-30: a task run costs 0.1 credits, priced at USD 0.10 | capture: sha256:f5ebee36d9ae9318f9eed86d2b18bda1553b3aefb3b933c1a3e4178f26d05556 | quote: Every run of a task you created from a prompt or a demonstration costs 0.1 credits (\$0.10), whatever the run does inside the browser.
  - [2] 2026-10-30: the docs pricing table lists the Free plan as USD 5 of free credits a month | capture: sha256:f5ebee36d9ae9318f9eed86d2b18bda1553b3aefb3b933c1a3e4178f26d05556 | quote: $5 free credits/month

## Anchor Browser (Crawling)

- `crawler-scraper/anchor-browser` | qualifies-with-caveat | evidence documented | binding request-rate | category headless browser
- needs card unknown, phone unknown, ID no, institution no | verified 2026-11-02T01:02:34.146Z (live) | stale on 2026-12-03
- url https://anchorbrowser.io/pricing
- free tier: 5 credits a month, up to 5 concurrent browsers and up to 500 browser sessions; a task run costs 0.1 credit, and a credit is USD 1.00 of overage, so the allowance is USD 5 a month | unit: mixed | metered on: wall-clock | read on: 2026-10-30 | source: [1] | note: The docs table states USD 5 of free credits a month and the pricing card 5 credits a month; overage is USD 1.00 a credit on every paid plan, so the two figures are one allowance
- per-object cap: not applicable: the unit is a session | source: [1]
- retention: 7 days of data retention on the free plan | days: 7 | source: [1]
- egress: not applicable | metered: no | source: [1]
- identity: email | detail: 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
- interface: rest
- limits:
  - request-rate (binding): 5 concurrent browsers and 5 session creations a minute on the free plan [2]
  - request-rate (binding): 2,000 requests a minute per API key by default on Web Unlocker, a route outside the plan's concurrent-browser limit; higher limits are available on request [3]
- limits note: unverified: neither the Web Unlocker guide nor the docs plan table says whether the Free plan can call Web Unlocker
- binding note: 5 session creations a minute and 5 concurrent browsers on the free plan
- interface detail: 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: free tier, session limits and retention read on the vendor's pricing and docs pages
