MOBILE SERP TRACKER

PRICING

Competitor Comparison

Proxies.sx advantage: real mobile carrier IPs by default (others use datacenter), includes AI Overviews + PAA, no account needed, pay per query with USDC.

API REFERENCE

Endpoint

GET https://api.proxies.sx/v1/x402/serp

Parameters

Authentication

No API key needed. Uses x402 protocol — HTTP 402 Payment Required flow:

# Step 1: Request without payment → get 402 with price + wallet
curl "https://api.proxies.sx/v1/x402/serp?query=best+coffee+shops&country=us"

# Step 2: Send $0.003 USDC to the recipient wallet on Solana or Base

# Step 3: Retry with payment signature
curl "https://api.proxies.sx/v1/x402/serp?query=best+coffee+shops&country=us" \
  -H "Payment-Signature: <solana_or_base_tx_hash>"

FAQ

How fast is it?

Typical response time is 5-15 seconds. The query goes through a real mobile proxy, hits Google, parses the HTML, and returns structured JSON.

What if Google serves a CAPTCHA?

CAPTCHAs are rare on real carrier IPs (under 5% of requests). If one occurs, the API returns a 502 with a hint to retry. Real mobile IPs have much better CAPTCHA rates than datacenter or residential proxies.

Can I scrape thousands of queries?

Yes. There's no rate limit on the API itself — each request costs $0.003. For high volume, use Solana for faster settlement (~400ms vs ~2s on Base).

Is pagination supported?

Yes. Use the start parameter with increments of 10 (0 = page 1, 10 = page 2, 20 = page 3, etc.).

What countries work best?

All countries work. The proxy rotates through real carrier IPs. US, UK, Germany, France, Spain, and Poland have the highest device counts.
