Normalize URL
seo.normalize_url
Overview
Rewrite one URL with a named RFC 3986 profile and keep the original string beside the result We never open a connection, resolve DNS, or follow a redirect. The answer is a structured fact or policy result you can store. A successful call costs 1 execution credit.
Two strings that differ only by case or a default port should compare equal without anyone fetching them.
Reliability
seo.normalize_url is stable for identical input. Identical input always produces identical JSON. SEO_INPUT_REQUIRED means a required field is missing or has the wrong shape, so send the published object rather than a guessed map; retrying unchanged will not help. SEO_INPUT_TOO_LARGE means a value exceeds its ceiling, so trim it. SEO_HTML_MALFORMED means the HTML could not be parsed under the offline HTML contract, so fix the markup. SEO_XML_MALFORMED means the XML is not well-formed, so correct it. SEO_XML_DOCTYPE_NOT_ALLOWED means the XML includes a DOCTYPE declaration, so strip the DOCTYPE and resend; we refuse DTDs rather than expanding entities. SEO_JSONLD_MALFORMED means a JSON-LD block is not usable JSON, so correct it. SEO_PROFILE_UNKNOWN means the named profile is not bundled, so send one of the published profile ids. SEO_TOO_MANY_RECORDS means a list exceeded its ceiling, so split the batch. SEO_GRAPH_LIMIT_EXCEEDED means the graph exceeded its node or edge ceiling, so shrink it. SEO_INVALID_URL means a URL string is not a usable RFC 3986 URI, so send an absolute URI. SEO_OBSERVATION_INCOMPLETE means required observation coverage is missing, so add the missing evidence. SEO_INPUT_CONFLICT means two fields that cannot be used together were both supplied, so drop one. Retrying an unchanged request will not help.
Context footprint
Returns a compact structured record. A successful call costs 1 execution credit.
When to use it
When you need a stable syntactic identity key from a URL you already hold, including resolving a relative link against a page URL.
When you still need HTTP status, or you want a search-engine canonical rather than RFC 3986 rewrite.
Scope
Non-goals
- Does not fetch a URL, resolve DNS, or run a browser
- Does not predict ranking, choose a winner, or claim live index status
- Does not follow redirects or claim search-engine equivalence

How we handle your data
What this means
This skill may receive sensitive content and may return submitted, transformed, extracted, or reformatted content.
Squillify guarantees
- Runs inside Squillify
- This skill runs inside Squillify.
- Payloads are not sent to an external service by this skill.
- Squillify does not permanently store submitted payloads.
- Telemetry records metadata only, not submitted content.
- Submitted payloads are not used for training.
- Submitted payloads are not reviewed by humans.
- This skill does not target sensitive data.
- The response may contain submitted or transformed content.
Your responsibility
Squillify does not determine whether submitted content is sensitive. Your application is responsible for deciding what data it is allowed to submit. Your application is responsible for securing the response.
Input schema
| Field | Type | Required | Description |
|---|---|---|---|
| url | string | Yes | Required. The URL to rewrite, up to 8192 UTF-8 bytes. |
| baseUrl | string | No | Absolute URL used only to resolve a relative url. Omit it when url is already absolute. |
| profile | string | No | Named syntactic profile. Omit it and we apply seo.safe.url.normalization@1. Query parameters are never stripped or sorted. |
Output schema
| Field | Type | Required | Description |
|---|---|---|---|
| original | string | Yes | The url string you sent, unchanged. |
| normalized | string | Yes | Syntactic rewrite under the named profile. |
| changed | boolean | Yes | True when normalized differs from original. |
| transformations | array | Yes | Named steps that actually changed the value, in application order, such as scheme_case or dot_segments. |
| equivalence | string | Yes | Always SYNTACTIC_ONLY. This is not a canonical-selection claim. |
| profile | string | Yes | Effective profile id that produced normalized. |
| identityKey | string | Yes | Syntactic identity key, equal to normalized under this profile. |
