# SignalHire API Skill

This skill provides context and instructions for using the SignalHire API to retrieve contact information (emails, phone numbers, social media profiles) from a global database of professionals.

## Authentication
To access the SignalHire API, an API key is required. The API key must be included in the `apikey` request header.

If the user hasn't provided their SignalHire API key in their request or environment, ask them to provide it before making API calls. Ensure it is kept secure and not exposed publicly.

## Endpoints

### 1. Person API
Retrieves comprehensive profile and full contact details about a specific individual based on unique identifiers (e.g., LinkedIn® profile links, email addresses, phone numbers, or ID).
- **Use Case:** Find a specific person's contact info.
- **Rate Limit:** 600 items per minute.
- **Callback URL:** The Person API is asynchronous — SignalHire POSTs the result to a callback URL you provide. See **Callback Setup** below.

### 2. Search API
Searches for individuals or companies using various filters (e.g., job title, location, industry). Returns a brief overview of information **without** contact details.
- **Use Case:** Lead generation, talent acquisition, market research.
- **Rate Limit:** 1 concurrent request.

---

## Callback Setup

The Person API is asynchronous: you submit a request with a `callbackUrl`, and SignalHire POSTs the enriched result to that URL when ready.

### Requirements
- A publicly reachable HTTPS endpoint that accepts POST requests with JSON body.
- A **shared secret** in the callback URL as a query parameter (e.g. `?k=<secret>`), because SignalHire controls the outbound request and cannot set custom headers.

### Step 1 — Deploy a webhook receiver
You need an HTTP server that:
1. Accepts `POST /signalhire/callback?k=<secret>`
2. Validates the `k` parameter against your stored secret
3. Saves the JSON payload to a known file (e.g. `signalhire_result.json`) so the agent can read it back

A minimal Flask example:
```python
import hmac, os
from flask import Flask, request, jsonify
import json

app = Flask(__name__)
SECRET = os.environ["SIGNALHIRE_WEBHOOK_SECRET"]

@app.before_request
def auth():
    if request.method == "POST":
        k = request.args.get("k", "")
        if not hmac.compare_digest(k, SECRET):
            return jsonify({"error": "unauthorized"}), 403

@app.route("/signalhire/callback", methods=["POST"])
def callback():
    payload = request.get_json()
    with open("signalhire_result.json", "w") as f:
        json.dump(payload, f, indent=2)
    return jsonify({"status": "accepted"}), 200

## Description:

The SignalHire skill guides agents in using the SignalHire API to search professional profiles and companies, enrich contact details, and handle asynchronous callback-based results.

This skill is ready for commercial/non-commercial use.

## Publisher:

[nts](https://clawhub.ai/user/nts)

### License/Terms of Use:

MIT-0

## Use Case:

External users and developers use this skill to search for prospects or companies and request contact enrichment through SignalHire. It is intended for workflows that have a legitimate SignalHire account and a lawful basis for handling personal contact data.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: The skill handles personal contact data returned by SignalHire.

Mitigation: Use it only with a legitimate SignalHire account and a lawful basis for contact lookup, and avoid unnecessary storage or sharing of enrichment results.

Risk: Callback-based enrichment can expose webhook endpoints and callback secrets.

Mitigation: Prefer a presecured callback service, validate shared secrets, use HTTPS, and rotate callback secrets when exposure is suspected.

Risk: API keys and callback URLs may be exposed through shell commands, logs, or command history.

Mitigation: Keep credentials in environment variables or a managed secret store and avoid echoing sensitive values into logs or persistent command history.
