[Avatars provided by Unavatar](https://unavatar.io)
``` **Valid placements** Site footer, about page, credits page, or any page that renders avatars. **Mobile apps and non-web products** If avatars are displayed in a mobile app, desktop app, browser extension, email, or any non-web surface, add the attribution link on your app's marketing site, app store listing description, or credits screen. **Requirements for attribution to be valid** We reserve the right to revoke free-tier access for any website or product that does not comply with the attribution requirements described in this document: - Double-check the href. It must point to [https://unavatar.io](https://unavatar.io/) directly — no redirects, no URL shorteners, no tracking wrappers. - Make sure it's crawlable. The link must be present in the rendered HTML and not blocked by robots.txt, authentication, or region gating. - Avoid nofollow or noindex. We need a standard, followable link. - target="\_blank" is allowed. ### Remove attribution Attribution is only required on the free plan. [Upgrade to the PRO plan](https://unavatar.io/checkout) to remove the requirement. ## Authentication Anonymous requests work without authentication. They are limited to 25 requests/day per IP address. For [PRO](https://unavatar.io/checkout) users, the requests must include the API key as the `x-api-key` request header: ```bash curl "https://unavatar.io/github/kikobeats" -H "x-api-key: YOUR_API_KEY" ``` ```javascript await fetch('https://unavatar.io/github/kikobeats', { headers: { 'x-api-key': 'YOUR_API_KEY' } }) ``` ```python import requests response = requests.get( 'https://unavatar.io/github/kikobeats', headers={'x-api-key': 'YOUR_API_KEY'} ) ``` ```golang package main import "net/http" func main() { req, _ := http.NewRequest("GET", "https://unavatar.io/github/kikobeats", nil) req.Header.Set("x-api-key", "YOUR_API_KEY") resp, _ := http.DefaultClient.Do(req) defer resp.Body.Close() } ``` ```ruby require 'net/http' require 'uri' uri = URI('https://unavatar.io/github/kikobeats') request = Net::HTTP::Get.new(uri) request['x-api-key'] = 'YOUR_API_KEY' response = Net::HTTP.start(uri.hostname, uri.port, use_ssl: true) do |http| http.request(request) end ``` ```php $ch = curl_init('https://unavatar.io/github/kikobeats'); curl_setopt($ch, CURLOPT_HTTPHEADER, [ 'x-api-key: YOUR_API_KEY', ]); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response = curl_exec($ch); curl_close($ch); ``` If the API key is invalid, the service returns `401` with code `EAPIKEY`. Rate limit status can be verified using these response headers: | Header | Description | | ------------------------ | -------------------------------------------------------------- | | `x-rate-limit-limit` | Maximum anonymous requests allowed in the current daily window | | `x-rate-limit-remaining` | Requests remaining in the current window | | `x-rate-limit-reset` | UTC epoch seconds when the current window resets | ```bash $ curl -I https://unavatar.io/github/kikobeats x-rate-limit-limit: 25 x-rate-limit-remaining: 24 x-rate-limit-reset: 1744243200 ``` ## Pricing Unavatar pricing is simple: you can start on the anonymous free tier, then authenticate with `x-api-key` to get additional included usage and metered billing for higher volume. | Scenario | Included free usage | Billing | | -------------------------------------------- | ---------------------- | -------------------------------- | | Anonymous (no API key) | 25 requests/day per IP | Free | | Authenticated origin requests (`x-api-key`) | 50 origin requests/day | Metered monthly after free quota | | Proxy requests (`datacenter`, `residential`) | None | Always metered | For higher usage, the **[PRO](https://unavatar.io/checkout)** plan is usage-based billing that includes the 50 free daily origin requests, metered overage, and custom TTL. Every request has a cost in tokens (**\$0.005 per token**) based on the proxy tier needed to resolve the avatar: | Proxy tier | Tokens | Cost | | ----------- | :----: | :-----: | | Origin | 1 | \$0.005 | | Datacenter | +2 | \$0.015 | | Residential | +4 | \$0.025 | The proxy tier used is returned in the `x-proxy-tier` response header, and the total cost in the `x-unavatar-cost` header. ```bash $ curl -I -H "x-api-key: YOUR_API_KEY" https://unavatar.io/instagram/kikobeats x-pricing-tier: pro x-proxy-tier: origin x-unavatar-cost: 1 ``` To upgrade, visit [unavatar.io/checkout](https://unavatar.io/checkout). After completing the payment, you'll receive an API key. ## Cache Unavatar caches avatar lookups to make repeated requests fast and stable: - The first request for a resource fetches the avatar from upstream and stores it in cache - Following requests are served from cache until the [TTL](https://unavatar.io/docs#ttl) expires. For example, if you set `ttl=1h`, the cache behavior looks like this: | Time | Request | Cache status | Plan impact | | ----- | ----------------------- | ----------------------------------- | -------------------------- | | 10:00 | `GET /github/kikobeats` | MISS (fetched from upstream) | Counts as 1 origin request | | 10:05 | `GET /github/kikobeats` | HIT (served from cache) | No usage consumed, no cost | | 10:40 | `GET /github/kikobeats` | HIT (served from cache) | No usage consumed, no cost | | 11:02 | `GET /github/kikobeats` | MISS (TTL expired, cache refreshed) | Counts as 1 origin request | | 11:10 | `GET /github/kikobeats` | HIT (served from cache) | No usage consumed, no cost | To check the cache status in real requests, inspect these response headers: | Header | What to look for | | ---------------- | --------------------------------------------------------------------------------------- | | `x-cache-status` | `HIT` means served from cache. `MISS` means fetched/refreshed from upstream. | | `cache-control` | Shows cache policy and effective TTL (for example `public, max-age=3600` for `ttl=1h`). | ```bash $ curl -I -H "x-api-key: YOUR_API_KEY" "https://unavatar.io/github/kikobeats?ttl=1h" cache-control: public, max-age=3600 x-cache-status: HIT ``` The same rule applies to anonymous requests: cache hits are free and do not consume the `25 requests/day` limit. After TTL expiration, the next request refreshes the cache and is billed/rate-limited according to the request tier (`anonymous`, `origin`, `datacenter`, or `residential`). ## Query parameters ### TTL Type: `number` or `string`\ Default: `'24h'`\ Range: from `'1h'` to `'28d'` It determines the maximum quantity of time an avatar is considered fresh. e.g., [unavatar.io/github/kikobeats?ttl=1h](https://unavatar.io/github/kikobeats?ttl=1h) When you look up for a user avatar for the very first time, the service will determine it and cache it respecting TTL value. The same resource will continue to be used until reach TTL expiration. After that, the resource will be computed, and cache as fresh, starting the cycle. ### Fallback Type: `string` or `boolean` When it can't be possible to get a user avatar, a fallback image is returned instead, and it can be personalized to fit better with your website or application style. You can get one from **boringavatars.com**: e.g., [unavatar.io/github/37t?fallback=https://source.boringavatars.com/marble/120/1337_user?colors=264653r,2a9d8f,e9c46a,f4a261,e76f51](https://unavatar.io/github/37t?fallback=https://source.boringavatars.com/marble/120/1337_user?colors=264653r,2a9d8f,e9c46a,f4a261,e76f51) or **avatar.vercel.sh**: e.g., [unavatar.io/github/37t?fallback=https://avatar.vercel.sh/37t?size=400](https://unavatar.io/github/37t?fallback=https://avatar.vercel.sh/37t?size=400) or a static image: e.g., [unavatar.io/github/37t?fallback=https://avatars.githubusercontent.com/u/66378906?v=4](https://unavatar.io/github/37t?fallback=https://avatars.githubusercontent.com/u/66378906?v=4) or even a base64 encoded image. This allows you to return a transparent, base64 encoded 1x1 pixel GIF, which can be useful when you want to use your own background colour or image as a fallback. e.g., [unavatar.io/github/37t?fallback=data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==](https://unavatar.io/github/37t?fallback=data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==) You can pass `fallback=false` to explicitly disable this behavior. In this case, a *404 Not Found* HTTP status code will returned when is not possible to get the user avatar. ### JSON The service returns media content by default. This makes the service easier to consume directly from HTML markup. In case you want to get a JSON payload as response, just pass `json=true`: e.g., [unavatar.io/github/kikobeats?json](https://unavatar.io/github/kikobeats?json) ## Providers ### Apple Music Get artwork for any Apple Music artist, album, or song.

Domain-shaped paths try DuckDuckGo, Google, Microlink in order until one returns an image, same as the explicit `/domain/:key` route. e.g., [unavatar.io/domain/microlink.io](https://unavatar.io/domain/microlink.io) ### Dribbble Get any Dribbble designer's profile picture by their username. e.g., [unavatar.io/dribbble/omidnikrah](https://unavatar.io/dribbble/omidnikrah) ### DuckDuckGo Get the favicon or logo for any domain via DuckDuckGo's icon service. Useful as a fallback when a domain doesn't expose its favicon directly. e.g., [unavatar.io/duckduckgo/microsoft.com](https://unavatar.io/duckduckgo/microsoft.com) ### Email Resolve user avatars from an email address with a single URL. The `/email/:key` route uses the same provider chain as a bare `/user@domain` path: the service tries Gravatar, GitHub in order until one returns an image. No API keys and no SDK are required. When the path looks like an email, unavatar walks that chain until a provider succeeds. You can also skip the chain and call a named email provider directly when you know where the avatar should come from. Automatic resolution Pass the address as the only path segment, or prefix it with `email/`. The API auto-detects email-shaped inputs and runs the same chain (Gravatar, GitHub). - Typed route `unavatar.io/email/{email}`: [unavatar.io/email/hello@microlink.io](https://unavatar.io/email/hello@microlink.io) - Bare path `unavatar.io/{email}`: [unavatar.io/hello@microlink.io](https://unavatar.io/hello@microlink.io) Explicit providers Target a specific provider when you know where the avatar comes from. - Gravatar (`unavatar.io/gravatar/{email-or-hash}`) — email is normalized and SHA-256 hashed; 64-hex SHA-256 or 32-hex MD5 passes through.

When an endpoint returns JSON, the shape is predictable so you can parse it reliably in your app: | Field | Type | Present in | Description | | --------- | -------------- | ------------------------------- | ------------------------------------------------ | | `status` | `string` | all JSON responses | One of: `success`, `fail`, `error`. | | `message` | `string` | all JSON responses | Human-readable summary for display/logging. | | `data` | `object` | `success` | Response payload for successful requests. | | `code` | `string` | `fail`, `error` | Stable machine-readable error code. | | `more` | `string (URL)` | most `fail` / `error` responses | Documentation URL with troubleshooting details. | | `report` | `string` | some `error` responses | Support contact channel (for example `mailto:`). | ## Response Headers These headers help you understand pricing, limits, and request diagnostics. | Header | Purpose | | ------------------------ | --------------------------------------------------------- | | `x-pricing-tier` | `free` or `pro` — the plan used for this request | | `x-timestamp` | Server timestamp when request was received | | `x-unavatar-cost` | Token cost of the request (avatar routes only) | | `x-proxy-tier` | Proxy tier used: `origin`, `datacenter`, or `residential` | | `x-rate-limit-limit` | Maximum requests allowed per window (free tier only) | | `x-rate-limit-remaining` | Remaining requests in current window (free tier only) | | `x-rate-limit-reset` | UTC epoch seconds when window resets (free tier only) | | `retry-after` | Seconds until rate limit resets (only on 429 responses) | ```bash $ curl -I -H "x-api-key: YOUR_API_KEY" https://unavatar.io/github/kikobeats x-pricing-tier: pro x-timestamp: 1744209600 x-unavatar-cost: 1 x-proxy-tier: origin x-rate-limit-limit: 50 x-rate-limit-remaining: 49 x-rate-limit-reset: 1744243200 ``` ## Response Errors Expected errors are known operational cases returned with stable codes. - **Client-side issues** return `status: "fail"` (HTTP `4xx`). - **Service-side issues** return `status: "error"` (HTTP `5xx`). - Unknown failures return `EINTERNAL` (HTTP `500`). - Use the `code` for programmatic handling in clients. - Use the `message` to show user-facing feedback. - `more` links to documentation for common fixes. - `report` (when present) indicates how to contact support for server errors. | HTTP | Code | Typical trigger | | ---- | -------------------- | ------------------------------------------- | | 400 | `ESESSIONID` | Missing `session_id` in `/checkout/success` | | 400 | `ESESSION` | Checkout session not paid or not found | | 400 | `ESIGNATURE` | Missing `stripe-signature` header | | 400 | `EWEBHOOK` | Invalid/failed Stripe webhook processing | | 400 | `EAPIKEYVALUE` | Missing `apiKey` query parameter | | 400 | `EAPIKEYLABEL` | Missing `label` query parameter | | 401 | `EEMAIL` | Invalid or missing authenticated email | | 401 | `EUSERUNAUTHORIZED` | Missing/invalid auth for protected routes | | 401 | `EAPIKEY` | Invalid `x-api-key` | | 403 | `ETTL` | Custom `ttl` requested without pro plan | | 403 | `EPRO` | Provider restricted to pro plan | | 404 | `ENOTFOUND` | Route not found | | 404 | `EAPIKEYNOTFOUND` | API key not found | | 409 | `EAPIKEYEXISTS` | Custom API key already exists | | 409 | `EAPIKEYLABELEXISTS` | API key label already exists | | 409 | `EAPIKEYMIN` | Attempt to remove last remaining key | | 429 | `ERATE` | Anonymous daily rate limit exceeded | | 500 | `ECHECKOUT` | Stripe checkout session creation failed | | 500 | `EAPIKEYFAILED` | API key retrieval after checkout failed | | 500 | `EINTERNAL` | Unexpected internal server failure | ## Contact If you have any suggestion or bug to report, please contact to ust mailing to [hello@unavatar.io](mailto:hello@unavatar.io). ~~~ ## llms-full Not found.
