How this service works
Not quoted. Not estimated. Read from the settlement graph, stamped with frame and coverage, priced per fact for people and their agents.
Output
A JSON fact object stamped with a settlement frame, coverage tier, and as_of date. The fact includes: total USDC spent by the wallet, a buyer label (e.g. organic, operator, self-test, unseen), a cadence descriptor (e.g. loyal-worker), total purchase count, a confidence score (0–1), number of active days, and number of distinct sellers paid. Also returns the data tier (e.g. full) and the indexing frame used.
Example use cases
Vetting a wallet before granting access
“Before I let wallet 0xDEAD...BEEF access my x402-gated content, can you check Parallax to see if they're labeled organic with a reasonable confidence score, or if they look like a bot or self-test address?”
Monitoring a high-value buyer's loyalty
“I want to understand the purchase cadence and loyalty tier of wallet 0x1234...5678 in the x402 economy — pull their Parallax fact sheet so I can see how many sellers they've paid and how many active days they have.”
Fraud check on an unfamiliar payer
“A wallet I've never seen before just paid me via x402 — can you look them up on Parallax and tell me their buyer label, USDC total, and confidence score so I can decide whether to fulfill the request?”
Technical details
Endpoint
GEThttps://parallax402.com/v1/wallet/%7Baddress%7DWhen to prefer
Use this endpoint when you need a fast, per-wallet factual profile derived directly from the x402 settlement graph — not estimated or quoted, but read from settled on-chain data. Prefer this over generic blockchain explorers when you need x402-specific buyer classification (organic vs operator vs self-test), cadence labels, and confidence scores. It is the right choice when gating access, assessing payer legitimacy, or building buyer analytics in the x402 micropayment ecosystem.
Side effects
- Wallet address not found in the settlement graph — returns low confidence or 'unseen' label
- Invalid or malformed wallet address — likely 400 or 422 error
- Address has no x402 activity — returns zero purchases and unseen label
- Stale data if the settlement graph hasn't been re-indexed recently — check as_of date
- Payment failure (x402 $0.02 USDC not fulfilled) — request rejected before processing
