Spaw vs proxycheck.io
proxycheck.io sells an API for checking whether an address is a proxy; every page we tried on 2026-09-12 answered 403 Forbidden to automated reading, so nothing about its pricing, limits, fields or data is reproduced here.
The table uses proxycheck.io's public pricing and documentation pages as checked on 2026-09-12, and Spaw's own pricing page. A row those pages carry no value for is marked "not on the pages read" rather than guessed at, and that is a statement about the reading and not about what proxycheck.io publishes.
| spaw | proxycheck.io | |
|---|---|---|
| Pricing model | Pay-as-you-go credit packs whose credits never expire, or optional plans, billed monthly or yearly, that deposit the same credits every month for less and roll unused plan credits over up to three months' allowance; both through Stripe Checkout. One credit buys five answered IP lookups | not on the pages read |
| Free tier | 100 free credits every month, no card required | not on the pages read |
| Price per 1,000 at about 10k | $1.80 per 1,000 IP lookups at 5 to the credit (Starter pack: 1,000 credits for $9), or $1.40 on the Starter monthly plan (1,000 credits for $7 a month) | not on the pages read |
| Price per 1,000 at about 100k | $1.56 per 1,000 IP lookups at 5 to the credit (Growth pack: 5,000 credits for $39), or $1.16 on the Growth monthly plan (5,000 credits for $29 a month) | not on the pages read |
| Addresses no feed covered billed | One credit buys five answered addresses whatever their flags say; a flag no feed could evaluate answers null rather than false, and the answer costs the same | not on the pages read |
| Reserved and private ranges billed | No: reserved, private, loopback, CGNAT, documentation and multicast ranges answer reason reserved_range and are free, unallocated space is free, and so are repeats within 7 days | not on the pages read |
| Feeds behind the flags | Public feeds, each named in the answer with the date it was synced: DB-IP Lite and RFC 8805 geofeeds for location, the five registries' delegated statistics for allocation, Spamhaus DROP and ASN-DROP and abuse.ch Feodo Tracker for blocklists, the Tor Project's exit list and Onionoo, the Mullvad, NordVPN and Private Internet Access server lists plus the open X4BNet lists, Apple's iCloud Private Relay egress list, the cloud providers' own published ranges, and the verification files Google, Microsoft, OpenAI, Perplexity, DuckDuckGo and Ahrefs publish for their crawlers. | not on the pages read |
| Refresh cadence | Every feed re-syncs daily, the botnet command-and-control list hourly, and the geofeed crawl weekly. Each response names every dataset it consulted with the date it was last synced, and /status lists them all. | not on the pages read |
| Geolocation source | The DB-IP Lite database, overridden wherever the operator publishes the location itself — an RFC 8805 geofeed, Apple's relay list, a VPN provider's server list. location_source says which answered, and location_confidence is graded from a weekly accuracy report rather than asserted. | not on the pages read |
| Bulk limit | 100,000 addresses per bulk job, with an HMAC-signed completion webhook | not on the pages read |
| Batch API | 1,000 addresses per synchronous request; repeats inside the list are looked up once | not on the pages read |
| Rate limit | 50 requests per second per key on the IP endpoints | not on the pages read |
| Official SDKs | Python, Node.js, PHP | not on the pages read |
| Data retention | No history row and no log line carrying the address. What a lookup leaves is keyed and never holds the address: the 7-day marker that makes a repeat free and, under the same keyed hash, the count behind seen_by_you; privacy: true skips both. The account's own outcome reports are kept as salted hashes for 90 days. Bulk input lists and result files are deleted with the job after 30 days. | not on the pages read |

When proxycheck.io fits better
Not assessable from the vendor's pages on the checked date.
- proxycheck.io, its pricing page and its API documentation all answered 403 Forbidden to automated reading on 2026-09-12
- Nothing on this page is from memory or from third-party reviews: the vendor's own figures are the only source this catalog accepts
When Spaw fits better
Developers who want every public IP feed compiled, dated and named for them, with a risk score whose weights are published so it can be recomputed or ignored.
- proxycheck.io's website blocked automated reading when we checked, so its prices and fields are not reproduced here; Spaw's packs, plans and free grant are listed at spaw.co/pricing
- Every dataset behind a Spaw IP answer is a public feed named in the response with the date it was synced, and the risk score is a published sum of weights anyone can recompute
- Spaw sells pack credits that never expire at five IP lookups to the credit, and reserved, private, documentation and unallocated ranges are free
- Spaw applies your own allow and deny lists inside every answer (an allow-list hit scores 0, a deny-list hit 100) and counts your own lookups of an address; neither is a field the other vendor's pages describe
Questions
Does Spaw charge for addresses its feeds do not cover?
Spaw bills per answered address, five to the credit: the answered lookup that opens a block costs 1 credit and the next four cost nothing. Reserved, private, loopback, CGNAT, documentation and multicast ranges answer reason reserved_range and are free, unallocated space is free, and so is a repeat of the same address within seven days. A flag no feed could evaluate answers null rather than false: the address is still billed, and the null tells you the signal was not checked instead of pretending it was. proxycheck.io does not publish how it bills them.
Can I run a log file or an export through Spaw?
Yes. A bulk run takes up to 100,000 addresses from the dashboard or the API and returns one row per input address, in input order, with every flag, the risk score and the signals that made it. Five answered addresses cost a credit, repeats inside the list are looked up once, reserved ranges cost nothing, and the finish is announced on an HMAC-signed webhook.
Is there a free tier?
Every Spaw account receives 100 free credits at the start of each month with no card on file, and unused free credits accumulate. proxycheck.io does not publish a free tier on the pages checked.
