web.redirects

stable 2 credits

Redirect chain of a URL, hop by hop (status and Location).

GET /v1/web/redirects

What you get#

A list of Web results in Onekey's unified shape, in data (an array). An empty array is a normal, successful answer and is charged like any other; a source that reports "nothing found" as an error returns a free 404 not_found instead.

What it costs#

2 credits for a fresh fetch, charged only when it succeeds.
Free when served from cache (0.2 credit for a cached response over 100 KB).
Free if the request is invalid (never charged) or the source fails or reports not found (refunded).

Parameters#

Name	Type	Required	Default	What it is	Constraints
`url`	string	yes	(required)	Absolute http(s) URL of the page (ports 80/443 only; private/internal hosts are refused)	max 2048 chars; must match `https?://[A-Za-z0-9](?:[A-Za-z0-9.-]{0,251}[A-Za-z0-9])?(?::(?:80\|443))?(?:[/?][\x21-\x5b\x5d-\x7e]*)?`; trimmed

Request#

curl "https://api.onekey.dev/v1/web/redirects?url=http%3A%2F%2Fpython.org%2F" \

Field mapping#

How this endpoint's source fields become Onekey's unified schema. Fields the source lacks come back as null.

Source path	Onekey field	Transform
`url`	`entity.url`	`safeUrl`
`status`	`ext.httpStatus`	`toNumber`
`location`	`entity.location`	`safeUrl`

Caching and freshness#

Fresh for about 10 minutes. Repeat calls in that window are served from cache and are free.
Between 10 minutes and 1 hour the cached copy is still served instantly and marked stale: true while Onekey refreshes it in the background.
If the source is down when a refresh is needed, the last copy can be served for up to 1 hour more (marked stale).
A "not found" is remembered for 2 minutes and is free.
The cache is shared across all customers, which is what keeps repeat calls cheap.

What can go wrong#

Status	Code	What to do
401	`unauthorized`	Check the `x-api-key` header.
402	`insufficient_credits`	Add credits; your balance must cover the price.
404	`not_found`	Unknown endpoint path.
422	`invalid_params`	Fix the parameters using the table above. Free.
429	`rate_limited`	Wait `Retry-After` seconds, then retry.
502	`upstream_error`	The source failed. Refunded; retry with backoff.

See Errors for the full list and retry guidance.

Status: stable (verified against the live source).
