Redeem a one-click unsubscribe link from an email

POST

/v1/email/unsubscribe

curl --request POST \
  --url 'https://api.hyperresearch.ai/v1/email/unsubscribe?u=example&c=example&sig=example'

• production

Keyless, and idempotent. This is the endpoint named by the List-Unsubscribe / List-Unsubscribe-Post headers on every non-legal email (RFC 8058): the mail client POSTs it with no session, so the HMAC over user, category and expiry is the whole authentication. Switches that one category off and leaves the other as it stands. A tampered, expired or unknown link is one 403 with one sentence — never a hint about whether the user exists. Legal notices are not switchable and no link is ever minted for one.

Parameters

Query Parameters

u

required

The user the link was minted for.

string

>= 3 characters <= 64 characters

The user the link was minted for.

c

required

The category to switch off: runs, product or onboarding.

string

>= 3 characters <= 16 characters

The category to switch off: runs, product or onboarding.

exp

Unix seconds the link stops working.

integer | null

Unix seconds the link stops working.

sig

required

HMAC over the three above.

string

>= 1 characters <= 128 characters

HMAC over the three above.

The category is off

Media typeapplication/json

object

runs

required

Emails about your own runs: the report is ready, the run stopped and was refunded, the run is waiting on a question. On by default.

boolean

product

required

Account housekeeping: a card was added, a payment was declined. On by default.

boolean

onboarding

required

Tips for a new account: a welcome when you sign up and, if no run has started, one reminder a day later. Separate from product, so turning these off never stops a payment-failed email. On by default.

boolean

legal_notices_always

required

Always true. Notice of a material change to the Terms, of the service being discontinued, or of a security incident is sent whatever these switches say — it is an obligation under the agreement, not a subscription. There is no field to turn it off and no column behind one.

boolean

Headers

Retry-After

integer

Seconds to wait before retrying. Always present on a 429.

RateLimit-Policy

string

Example

"reads";q=60;w=60

The quota policy this request was counted against (draft-ietf-httpapi-ratelimit-headers): "<bucket>";q=<requests>;w=<window seconds>, e.g. "reads";q=60;w=60. Buckets: reads 60/min, status 600/min, creates 10/min, writes 20/min per credential; public 300/min per network on keyless routes.

RateLimit

string

Example

"reads";r=57;t=41

Remaining quota in the current window: "<bucket>";r=<remaining>;t=<seconds until reset>, e.g. "reads";r=57;t=41.

X-RateLimit-Limit

integer

Requests allowed per window in this bucket (legacy form of RateLimit-Policy).

X-RateLimit-Remaining

integer

Requests left in this window (legacy form of RateLimit).

X-RateLimit-Reset

integer

Unix time (seconds) when the window resets.

X-RateLimit-Bucket

string

Which bucket counted the request: reads, status, creates, writes or public.
