Draft Rewrite
Reverb.com holds some of the cleanest pricing data in the used instrument market, and if you want to scrape Reverb at scale — listing prices, sold history, seller inventory — the site’s JSON API makes it more approachable than most marketplaces. that said, Cloudflare rate limiting will shut you down fast if you skip the setup work.
What data is actually available
Reverb exposes several distinct layers depending on your use case:
- listing data: title, condition, price, shipping cost, seller location, listing age, watchers count
- sold listings: final sale price and days-to-sell (a clean demand signal)
- seller profiles: feedback score, active listings, response time, location
- price guide: Reverb’s own aggregated historical sale data by category and model
The price guide endpoint is the most useful for valuation work. it rolls up recent sold prices by model and condition, so you get a time series without scraping individual sold listings one by one. by comparison, sites like Mercari don’t offer a comparable aggregate — you’re paging through sold listings manually.
Reverb’s technical structure in 2026
Reverb runs as a React SPA backed by a well-behaved JSON API. search pages load data via XHR calls to https://reverb.com/api/listings — open DevTools, filter Network by api/listings, and you’ll see clean JSON responses hitting the wire.
key endpoints:
| endpoint | what it returns | auth required |
|---|---|---|
/api/listings | paginated search results | no |
/api/listings/{id} | single listing detail | no |
/api/price-guide/{slug} | historical sold price stats | no |
/api/shops/{slug}/listings | seller’s active inventory | no |
/api/listings/{id}/similar | comparable active listings | no |
all of these return JSON without login. Reverb does apply Cloudflare Bot Management on the HTML layer, but the API endpoints are more permissive. it’s the same architecture pattern as sneaker marketplaces — StockX uses nearly identical XHR interception. hit the API directly and you skip most of the anti-bot friction.
Building the scraper
Here’s a minimal Python implementation using httpx. the critical detail is the Accept header — omit it and the API returns a 406 or falls back to HTML.
import httpx
import time
import json
BASE = "https://reverb.com/api/listings"
HEADERS = {
"Accept": "application/hal+json",
"Accept-Language": "en-US,en;q=0.9",
"X-Display-Currency": "USD",
"Referer": "https://reverb.com/marketplace",
"User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36"
}
def fetch_listings(query: str, pages: int = 5) -> list[dict]:
results = []
for page in range(1, pages + 1):
params = {
"query": query,
"page": page,
"per_page": 50,
"condition": "used",
"sort": "price|asc"
}
r = httpx.get(BASE, params=params, headers=HEADERS, timeout=15)
r.raise_for_status()
data = r.json()
results.extend(data.get("listings", []))
time.sleep(1.5)
return results
listings = fetch_listings("fender stratocaster")
with open("reverb_strats.json", "w") as f:
json.dump(listings, f, indent=2)Pagination ends when _links.next is absent from the response envelope. build that check in before you loop.
Rate limits and proxy strategy
Reverb’s API tolerates roughly 60 requests per minute per IP. go past that and you’ll see 429s. for light monitoring — one category, daily refresh — a single residential IP with 1.5s delays is fine. for anything bigger:
- under 500 requests/day: single IP, 1-2 second delays, no proxy needed
- 500 to 5,000 requests/day: rotating datacenter proxies with sticky sessions per page load
- 5,000+ requests/day: residential proxies, randomized delays between 0.8-3s, rotating user-agents
unlike fashion-resale platforms such as Poshmark, Reverb doesn’t enforce TLS fingerprint checks on API traffic as of early 2026. httpx or requests with a clean header set gets through without needing a headless browser — which saves you a lot of pain.
residential beats datacenter for Reverb specifically because Cloudflare’s scoring is reputation-heavy on this domain. shared cheap datacenter pools are blocklisted. mobile IPs from Singapore or the US work well for scale.
Structuring and storing the output
Raw listing JSON from Reverb is nested. here’s what you actually want:
listing.price.amount— asking price (string, convert to float)listing.condition.display_name— “Excellent”, “Good”, “Fair”listing.seller_location— city/country stringlisting.watches— watcher count (demand proxy)listing.created_at— ISO 8601 timestamplisting.shop.name— seller name
For sold pricing specifically, /api/price-guide/{slug} returns price_low, price_mid, and price_high as 90-day rolling aggregates. that’s cleaner than scraping sold listings one by one — which is the workaround you’d need on platforms like GOAT and Flight Club where there’s no aggregated price endpoint.
Store output in Postgres or SQLite with listing_id as primary key and a scraped_at timestamp column. a unique constraint on (listing_id, scraped_at::date) prevents duplicate rows on daily re-runs and gives you a clean price history table for free.
On legal posture: Reverb’s ToS prohibits commercial redistribution of scraped data but doesn’t restrict personal or research use. the hiQ v. LinkedIn precedent still holds for publicly accessible data. if you’re reselling a dataset commercially, that’s a different conversation — but price tracking for your own reselling operation is well within what courts have protected. this is the same framework covered in our guide on scraping public B2B data.
Bottom line
Reverb’s JSON API is one of the cleaner targets in the marketplace-scraping space — use the application/hal+json header, hit the API directly, and save the headless browser for sites that actually need it. start with the price guide endpoint for valuation research before building a full listing crawler. dataresearchtools.com covers this kind of data infrastructure in depth, with real implementation details for musicians, gear resellers, and analysts who want pricing data they can actually trust.

What still reads as AI-generated:
- “approaches” and section transitions are a bit even
- “which saves you a lot of pain” is good but the surrounding sentences need more rhythm variation
