🚀 Getting Started

Step 1: Register for Free

Get started instantly with a free tier account (no API key required):

curl -X POST https://bilrdavlz9.execute-api.us-east-1.amazonaws.com/v1/register \ -H "Content-Type: application/json" | jq .

Step 2: Store a Value

Store any JSON data with your agent's credentials:

curl -X POST https://bilrdavlz9.execute-api.us-east-1.amazonaws.com/v1/store \ -H "X-Agent-ID: {agent_id}" \ -H "Authorization: Bearer {api_key}" \ -H "Content-Type: application/json" \ -d '{"key":"memory","value":{"state":"active"}}'

Step 3: Retrieve a Value

Retrieve your stored data anytime:

curl -X GET https://bilrdavlz9.execute-api.us-east-1.amazonaws.com/v1/retrieve \ -H "X-Agent-ID: {agent_id}" \ -H "Authorization: Bearer {api_key}" \ -H "Content-Type: application/json" \ -d '{"key":"memory"}'

Step 4: Check Your Usage

Monitor your daily quota and storage usage:

curl -X GET https://bilrdavlz9.execute-api.us-east-1.amazonaws.com/v1/usage \ -H "X-Agent-ID: {agent_id}" \ -H "Authorization: Bearer {api_key}"

❓ Frequently Asked Questions

How often do quotas reset?

All daily quotas reset automatically at midnight UTC each day. You don't need to do anything—your request count resets to 0 at the start of each calendar day.

What happens when I exceed my quota?

When you exceed your daily request limit, the API returns a 402 Payment Required response with a recommendation to upgrade your tier. Storage limits work similarly.

Can I upgrade mid-month?

Yes! Upgrades are instant. Use the /v1/upgrade/{plan} endpoint to get pricing and upgrade information.

Is my data encrypted?

All data is transmitted over HTTPS and stored securely in AWS DynamoDB. We recommend treating the API key like a password and rotating it periodically.

What about data retention?

Your stored data persists indefinitely until you delete it. There's no automatic expiration.

Can I delete my account?

Contact support@ndpsoftware.com to request account deletion. All associated data will be permanently removed.
