Free forever tier · No credit card · Your data is never stored
This is the real API, running in your browser. What you see is what your agent gets.
Free tier: 25 quotes/day — Pro removes the cap. The demo above runs on its own session quota (10 quotes per page load), so trying it never burns your 25.
Spot-price precedence: your entered price > live reference feed (gold-api.com, as-of timestamped) > 503 if the feed is over 30 minutes stale — enter your own price and quotes keep working.
Spot prices are volatile and can move between quote and close. All prices shown are indicative estimates and may be delayed — always verify the live spot price with your trusted source before finalizing any offer. SpotOffer provides quoting tools, not price guarantees.
Three mixed items, one call — the same engine Pro runs on 500-line CSVs.
| Item | Weight | Purity |
|---|---|---|
| Gold Eagle | 1 ozt | 24k |
| Silver Maples | 10 ozt | 99.9% |
| 14k scrap | 5.2 dwt | 14k |
In plain English — no API keys required to understand it.
An estate walk-in drops 50 mixed items on your counter. Paste the list, get every line priced off your number in seconds — not 20 minutes of spreadsheet.
Email the offer sheet to the seller's phone while they're still at the counter. The deal closes today, not "I'll think about it."
Export to QuickBooks in one click. We never store your sales records — there's nothing to leak, subpoena, or ransom.
SpotOffer sits at the front of your buy desk and chains straight into inventory.
Your agent prices any mix of metals, weights, and purities off your spot price — in plain English or JSON.
Print the offer sheet and close on the spot. Your system keeps the records — we keep nothing.
Your deals flow into inventory and on to your R3SELL listings. One chain, no retyping.
Paste the spec into a Muse custom connector and start quoting in plain English.
