+## Solving Captchas
+
+Sarin can solve captchas through third-party services and embed the resulting token into the request. Three services are supported via dedicated template functions: **2Captcha**, **Anti-Captcha**, and **CapSolver**.
+
+**Solve a reCAPTCHA v2 and submit the token in the request body:**
+
+```sh
+sarin -U https://example.com/login -M POST -r 1 \
+  -B '{"g-recaptcha-response": "{{ twocaptcha_RecaptchaV2 "YOUR_API_KEY" "SITE_KEY" "https://example.com/login" }}"}'
+```
+
+**Reuse a single solved token across multiple requests via `values`:**
+
+```sh
+sarin -U https://example.com/api -M POST -r 5 \
+  -V 'TOKEN={{ anticaptcha_Turnstile "YOUR_API_KEY" "SITE_KEY" "https://example.com/api" }}' \
+  -H "X-Turnstile-Token: {{ .Values.TOKEN }}" \
+  -B '{"token": "{{ .Values.TOKEN }}"}'
+```
+
+> See the **[Templating Guide](templating.md#captcha-functions)** for the full list of captcha functions and per-service support.

 > **Note:** Templating in URL host and scheme is not supported. Only the path portion of the URL can contain templates.

+> **Note:** Template rendering happens before the request is sent. The request timeout (`-T` / `timeout`) only governs the HTTP request itself and starts _after_ templates have finished rendering, so slow template functions (e.g. captcha solvers, remote `file_Read`) cannot cause a request timeout no matter how long they take.

+### JSON Functions
+
+Build JSON payloads programmatically without manual quoting or escaping. `json_Object` is the ergonomic shortcut for flat objects; `json_Encode` marshals any value (slice, map, etc.) to a JSON string.
+
+| Function                    | Description                                                                                            | Example                                               |
+| --------------------------- | ------------------------------------------------------------------------------------------------------ | ----------------------------------------------------- |
+| `json_Object(pairs ...any)` | Build an object from interleaved key-value pairs and return it as a JSON string. Keys must be strings. | `{{ json_Object "name" "Alice" "age" 30 }}`           |
+| `json_Encode(v any)`        | Marshal any value (slice, map, etc.) to a JSON string.                                                 | `{{ json_Encode (slice_Str "a" "b") }}` → `["a","b"]` |
+
+**Examples:**
+
+```yaml
+# Flat object with fake data
+body: '{{ json_Object "name" (fakeit_FirstName) "email" (fakeit_Email) }}'
+
+# Embed a solved captcha token
+body: '{{ json_Object "g-recaptcha-response" (twocaptcha_RecaptchaV2 "API_KEY" "SITE_KEY" "https://example.com") }}'
+
+# Encode a slice as a JSON array
+body: '{{ json_Encode (slice_Str "a" "b" "c") }}'
+
+# Encode a string dictionary (map[string]string)
+body: '{{ json_Encode (dict_Str "key1" "value1" "key2" "value2") }}'
+```
+
+> **Note:** Object keys are serialized in alphabetical order (Go's `encoding/json` default), not insertion order. For API payloads this is almost always fine because JSON key order is semantically irrelevant.
+

+| `time_NowUnixMilli`      | Current Unix timestamp (milliseconds)       | `{{ time_NowUnixMilli }}` → `1735689600123`                                     |
+| `time_NowRFC3339`        | Current time in RFC3339 format              | `{{ time_NowRFC3339 }}` → `"2026-02-26T21:00:00Z"`                              |
+| `time_Format(layout, t)` | Format a `time.Time` value with a Go layout | `{{ time_Format "2006-01-02" (strings_ToDate "2024-05-10") }}` → `"2024-05-10"` |

+## Captcha Functions
+
+Captcha functions solve a captcha challenge through a third-party solving service and return the resulting token, which can then be embedded directly into a request. They are intended for load testing endpoints protected by reCAPTCHA, hCaptcha, or Cloudflare Turnstile.
+
+The functions are organized by service: `twocaptcha_*`, `anticaptcha_*`, and `capsolver_*`. Each accepts the API key as the first argument so no global configuration is required — bring your own key and use any of the supported services per template.
+
+> **Important — performance and cost:**
+>
+> - **Each call is slow.** Solving typically takes ~5–60 seconds because the function blocks the template render until the third-party service returns a token. Internally the solver polls every 1s and gives up after 120s.
+> - **Each call costs money.** Every successful solve is billed by the captcha service (typically $0.001–$0.003 per solve). For high-volume tests, your captcha bill grows linearly with request count.
+
+**Common parameters across all captcha functions:**
+
+- `apiKey` - Your API key for the chosen captcha solving service
+- `siteKey` - The captcha sitekey extracted from the target page (e.g. the `data-sitekey` attribute on a reCAPTCHA, hCaptcha, or Turnstile element)
+- `pageURL` - The URL of the page where the captcha is hosted
+
