Authentication ​

All API requests require an API key passed via the X-API-Key header.

Getting an API Key ​

Contact us to get your API key:

Plans start at $49/mo with 10K quotes/day and unlimited swap builds + submits.

Using Your Key ​

Include the X-API-Key header in every request:

bash
curl -X POST https://api.venum.dev/v1/quote \
  -H "Content-Type: application/json" \
  -H "X-API-Key: vk_live_your_key_here" \
  -d '{ ... }'
typescript
const headers = {
  'Content-Type': 'application/json',
  'X-API-Key': process.env.VENUM_API_KEY,
};

Error Responses ​

Missing or invalid key returns 401:

json
{
  "error": "Invalid or missing API key"
}

Security ​

  • Always use HTTPS (https://api.venum.dev)
  • Never expose your API key in client-side code or public repositories
  • Rotate keys if compromised — contact us for a new key
  • Keys are scoped — an extension key cannot call API-only endpoints
