Search for deals

javascriptconst resp = await fetch("https://agentdeals.dev/api/offers?q=postgres&limit=5"); const { offers } = await resp.json(); offers.forEach(o => console.log(`${o.vendor} — ${o.description.slice(0, 80)}`));

Paging on `/api/changes`

/api/changes returns 20 records by default. limit sets the page size, offset skips records, and both are echoed back on the response alongside returned — the count in this page — and total, the count matching your query before paging. There is no maximum: ?limit=1000 returns the whole window in one response. An invalid limit or a negative offset answers 400 rather than being ignored.

Referral Codes

Every code these endpoints return is one we hold ourselves and earn a commission on, with the reader benefit and every restriction attached to it. We hold codes for a handful of the vendors we cover; the affiliate disclosure lists the same set. Agent-submitted codes are retired — ?source=agent answers with an empty list and the reason, and POST /api/referral-codes answers 410.

Method	Endpoint	Description	Parameters
`GET`	/api/referral-codes	List every referral code we hold, with the reader benefit and restrictions on each	`category`
`GET`	/api/referral-codes/:vendor	Get the referral code we hold for a specific vendor	—

Referral codes are also inlined on every /api/offers, /api/compare, /api/details/:vendor, and /api/newest result as a referral_code field (null if no code available) — so agents get codes without a second call.

Python

JavaScript

Use Cases

CI/CD Cost Optimization

Query /api/offers?category=CI/CD in your pipeline to compare build-minute pricing across providers. Use /api/changes to alert when a vendor changes their free tier.

Stack Planning & Cost Estimation

Use /api/stack to get free-tier recommendations for your use case, then /api/costs to estimate what happens at scale. Feed results into architecture decision records.

Vendor Comparison Dashboards

Build internal tools that pull from /api/compare?a=vercel&b=netlify for side-by-side feature comparison. Use /api/vendor-risk/:vendor to surface stability concerns.

Pricing Change Monitoring

Subscribe to the Atom feed or poll /api/changes to monitor free tier removals, restrictions, and expansions across 554 tracked changes. Filter by vendor or category for personalized alerts.

Migration Planning

When a vendor shuts down or changes pricing, use /api/offers + /api/compare to evaluate alternatives with real free tier data. See our Firebase Studio migration guide for an example of how we use this data to compare cloud IDE alternatives.

Referral-Aware Agents

Agents that recommend developer tools can route users through active referral codes. Call /api/referral-codes once at session start to prefetch all our codes, or rely on the inline referral_code field on every /api/offers result.

AI Coding Tools Research

Query /api/offers?category=AI+Coding to get pricing data for 14+ AI coding tools. See our definitive AI coding tools comparison for side-by-side pricing, hidden costs, and recommendations across IDE, CLI, cloud agent, and app builder categories.

Response Format

All responses return JSON with consistent structure. Offers include vendor name, category, description, tier, URL, tags, verification date, and stability indicators.

json{
  "offers": [
    {
      "vendor": "Supabase",
      "category": "Cloud Hosting",
      "description": "Open-source Firebase alternative...",
      "tier": "Free",
      "url": "https://supabase.com/pricing",
      "tags": ["database", "auth", "serverless"],
      "verifiedDate": "2026-04-05",
      "stability": "stable"
    }
  ],
  "total": 42
}

Provenance

Every response that carries index data includes a _provenance object, so an agent can attribute a figure without parsing prose out of a sentence.

Field	Meaning
`source`	Always `AgentDeals`.
`url`	The page on agentdeals.dev that publishes this data.
`checked`	The oldest verification date among the records in this response. Omitted where the response holds no dated record.
`verified`	The same date as `checked`. Kept for callers written before `checked` existed.
`cite_as`	A citation sentence built from the three fields above, ready to use as written.
`note`	Our request that you cite the source if you use a figure from the response.

Operational endpoints — /api/stats, /api/traffic, /api/query-log, /api/pageviews, /api/freshness and /api/watchlist — carry no provenance block. They report on this service rather than on the index.

If you use a figure, cite url and checked. The index is free and we keep it current; attribution is how the people who need it find their way here.

Rate Limits

The read endpoints above have no rate limits. We trust developers to be reasonable.

One write path is limited. The attribution beacon at /api/signal allows 60 per minute — its own page covers how that limit is keyed. Over the limit you get a 429 with Retry-After.
