Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.beta.paywithlocus.com/api/wrapped/credits/httpbun/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get headers

Get the full set of request headers as seen by the httpbun server. Returns every header sent in the request including those added by proxies and intermediaries. Useful for verifying TLS fingerprint headers, proxy additions, and client configuration.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/httpbun/get-headers \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### Get ip

Get the origin IP address of the request as seen by the httpbun server. Returns the IP address after any proxy or load balancer forwarding. Useful for verifying proxy configuration and checking what IP the target server sees.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/httpbun/get-ip \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### Get response headers

Request custom response headers from the httpbun server. The specified key-value pairs are sent as query parameters and returned as response headers. The response body contains a JSON object with all response headers. Useful for testing how HTTP clients handle custom or non-standard response headers.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `headers_param` | string | Yes | Comma-separated key=value pairs specifying response headers to set (e.g. 'X-Custom=hello,X-Other=world'). Each pair becomes a response header on the server's reply. |

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/httpbun/get-response-headers \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"headers_param":"<string>"}'
```

### Get status code

Request a specific HTTP status code response from the httpbun server. Returns the requested code, the actual status code received, and the response body. Useful for testing how HTTP clients handle various status codes (redirects, client errors, server errors).

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `status_code` | string | No | HTTP status code to request (100-599). The server responds with this status code along with a JSON body containing the code and its description. |

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/httpbun/get-status-code \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"status_code":"<string>"}'
```

### Inspect request

Inspect how a GET request appears to the server. Returns the method, query arguments, headers, origin IP, and full URL as seen by the httpbun server. Useful for debugging HTTP client behavior and verifying how requests are shaped after proxies, load balancers, or middleware modify them.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `query_params` | string | No | Comma-separated key=value pairs to send as query parameters (e.g. 'foo=bar,baz=123'). Each pair is split on '=' and sent as a separate query parameter. |

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/httpbun/inspect-request \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"query_params":"<string>"}'
```
