Overview

Package urlscan is the library behind the urlscan command line: the HTTP client, request shaping, and the typed data models for urlscan.io.

The Client here is the spine every command shares. It sets a real User-Agent, paces requests so a busy session stays polite, and retries the transient failures (429 and 5xx) that any public site throws under load. Build your endpoint calls and JSON decoding on top of it.

Constants

View Source
const BaseURL = "https://" + Host

BaseURL is the root every request is built from.

View Source
const DefaultUserAgent = "urlscan/dev (+https://github.com/tamnd/urlscan-cli)"

DefaultUserAgent identifies the client to urlscan.io. A real, honest User-Agent is both polite and the thing most likely to keep you unblocked.

View Source
const Host = "urlscan.io"

Host is the site this client talks to.

Types

type Client

type Client struct {
	HTTP      *http.Client
	UserAgent string
	// Rate is the minimum gap between requests. Zero means no pacing.
	Rate    time.Duration
	Retries int
	// contains filtered or unexported fields
}

Client talks to urlscan.io over HTTP.

func NewClient

func NewClient() *Client

NewClient returns a Client with sensible defaults: a 30s timeout, a 1s minimum gap between requests, and five retries on transient errors.

func (*Client) Get

func (c *Client) Get(ctx context.Context, url string) ([]byte, error)

Get fetches url and returns the response body. It paces and retries according to the client's settings. The caller owns nothing extra; the body is read fully and closed here.

func (*Client) Result

func (c *Client) Result(ctx context.Context, uuid string) (*ScanDetail, error)

Result fetches the full detail for a single scan by UUID.

func (*Client) Search

func (c *Client) Search(ctx context.Context, query string, size int) ([]*ScanResult, error)

Search queries the urlscan.io search endpoint and returns matching results.

type Config

type Config struct {
	UserAgent string
	Rate      time.Duration
	Retries   int
	Timeout   time.Duration
}

Config carries optional overrides a host or user passes in.

func DefaultConfig

func DefaultConfig() Config

DefaultConfig returns sensible defaults.

type Domain

type Domain struct{}

Domain is the urlscan.io driver. It carries no state; the per-run client is built by the factory Register hands kit.

func (Domain) Classify

func (Domain) Classify(input string) (uriType, id string, err error)

Classify turns any accepted input into the canonical (type, id). A 36-char UUID-like string (with hyphens) maps to "uuid"; a URL maps to "url"; everything else is treated as a search query.

func (Domain) Info

func (Domain) Info() kit.DomainInfo

Info describes the scheme, the hostnames a pasted link is matched against, and the identity reused for the binary's help and version.

func (Domain) Locate

func (Domain) Locate(uriType, id string) (string, error)

Locate is the inverse: the live https URL for a (type, id).

func (Domain) Register

func (Domain) Register(app *kit.App)

Register installs the client factory and every operation onto app.

type ScanDetail

type ScanDetail struct {
	UUID     string   `kit:"id" json:"uuid"`
	URL      string   `json:"url"`
	Domain   string   `json:"domain"`
	Title    string   `json:"title"`
	IP       string   `json:"ip"`
	Country  string   `json:"country"`
	City     string   `json:"city"`
	Server   string   `json:"server"`
	ASN      string   `json:"asn"`
	ASNName  string   `json:"asn_name"`
	IPs      []string `json:"ips"`
	Domains  []string `json:"domains"`
	Requests int      `json:"requests"`
}

ScanDetail is the full detail for a single scan result.

type ScanResult

type ScanResult struct {
	UUID    string `kit:"id" json:"uuid"`
	URL     string `json:"url"`
	Domain  string `json:"domain"`
	Time    string `json:"time"`
	Method  string `json:"method"`
	Title   string `json:"title"`
	IP      string `json:"ip"`
	Country string `json:"country"`
	Server  string `json:"server"`
}

ScanResult is a single entry from a search response.
