Agent API Gateway

Structured web data for AI agents. One API call.

Live product: https://agentapigw.dpdns.org (also https://agent-api-gateway.onrender.com)

Agents send a URL + schema type, get clean JSON. No markdown, no raw HTML — just fields.

Pricing & how to buy

Plan	Price	What you get	Buy
Free	$0	100 queries/mo, API keys, product/article schemas	Dashboard
1,000 credits	$1 once	One-time top-up; stacks on free or any subscription	Buy $1
Hobby	$29/mo	5,000 queries/mo (+ buy credit packs anytime)	Checkout
Pro	$99/mo	25,000 queries/mo (+ credit packs for bursts)	Checkout

Payments via Polar hosted checkout (card). Subscriptions set monthly limits; credit packs add bonus credits that stack and do not expire until used. After payment, use the dashboard to create API keys.

Public checkout API: POST /v1/billing/pricing/checkout with {"sku":"credits_1k"} → { url, session_id, amount_cents, credits }.

Public pricing API: GET https://agentapigw.dpdns.org/v1/billing/pricing (includes tiers + credit_packs).

Support

Business support email: support@agentapigw.dpdns.org
Polar public support email for org NexusCore (domain matches organization website https://agentapigw.dpdns.org).

Available schemas

Schema	Returns
product	name, brand, price, currency, in_stock, rating, review_count, description, image, specs, availability
article	title, author, date, reading_time, excerpt, content_summary, topics
company	name, description, founded, size, funding_total, industry, location, competitors

Auth

• Email + password (Better Auth) with required email verification
• Password reset via email
• GitHub OAuth (optional): GITHUB_CLIENT_ID + GITHUB_CLIENT_SECRET
• Google OAuth (optional): GOOGLE_CLIENT_ID + GOOGLE_CLIENT_SECRET

Same-email social sign-in is auto-linked to an existing account (trusted providers).

Email verification

Email/password accounts must verify before a session is created.

1. Set RESEND_API_KEY (and optionally EMAIL_FROM on a verified domain).
2. On sign-up, Better Auth emails a one-hour verification link.
3. Unverified sign-in is blocked and can resend the link from /login.

Locally without Resend, verification links are printed to the API console (not production).

GitHub OAuth

Create an OAuth App at https://github.com/settings/developers

Field	Value
Homepage URL	https://agentapigw.dpdns.org
Authorization callback URL	https://agentapigw.dpdns.org/api/auth/callback/github

Existing app (prod): Client ID Ov23liFQUYnTkcewcq2W → https://github.com/settings/applications/3733447
Generate a client secret there, then set both env vars on Render and restart.

Google OAuth

1. Open Google Cloud Console → Credentials
2. Create project (or pick one) → Create credentials → OAuth client ID
3. Application type: Web application
4. Authorized JavaScript origins: https://agentapigw.dpdns.org (and http://localhost:3000 for local)
5. Authorized redirect URIs:
   • https://agentapigw.dpdns.org/api/auth/callback/google
   • http://localhost:3000/api/auth/callback/google (local)
6. Copy Client ID + Client secret → set GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET on Render
7. Redeploy. /health should show "google_oauth": true

GET /health includes "github_oauth": true|false so you can confirm config without leaking secrets.

Local development

cp .env.example .env
npm install
npm run test:product
npm run dev:api
curl http://localhost:3000/health

Architecture

        Scraper fetches page HTML
        LLM extracts structured JSON
        Validator sanitizes business fields
        Cache result
        → { name, price, in_stock, ... }

Security hygiene

• .env is gitignored; use .env.example for placeholders only
• Never commit API keys, OAuth secrets, or database URLs
• npm run check:secrets scans tracked files for high-risk patterns
• Server/MCP errors redact secrets before logging or client responses
