Prax Data Services
Wallet, transfer and sanctions screening with reasons and references, as MCP tools for Claude, ChatGPT, Cursor and VS Code, or over REST. This is the technical reference: how to connect, what each tool returns, plans and credits. The product overview lives at prax-labs.com/data-services.
Free plan: 10 credits a day, no card. Nothing you look up is shared or added to a list. Use is subject to the Terms of Service. Product overview and pricing: prax-labs.com/data-services.
What one call looks like
What an analyst, an authorization engine or an agent gets back: verdict, reasons, references, timestamps. Never rule logic, thresholds or vendor names.
Who it is for
API tools
Today's public API covers digital-asset counterparties and transactions plus name screening; traditional rails are part of the Enterprise platform below. Quotas are credits per day: lookups 1, batches 10, the alerts feed 100 per pull. The badge shows where a tool unlocks.
Counterparty screening: wallets & contracts
Who is behind an address before money moves. Attribution, sanctions hits, lists, Prax alerts naming it and why, exposure to flagged parties, verdict: as a short narrative plus structured fields for your case system. Milliseconds; live=true adds on-chain screening.
Sanctions & watchlist screening: name or address
Pass a person, company or vessel name for fuzzy matching against the sanctions lists Prax tracks (names, aliases), or a wallet / contract address for an exact sanctions lookup. match / possible_match / no_match with programs, lists, linked addresses and scores: for onboarding, payments and periodic review.
Payment & transaction analysis
Chain facts plus the risk of both counterparties for a settled transaction: flagged recipients, look-alike addresses, malicious tokens, unlimited approvals, created contracts. Built for fraud and AML investigators who need reasons, not a score.
Pre-authorization transfer screening
Is it safe to send this amount of this asset from A to B? Verdict allow / review / block with reasons: sanctioned party, flagged counterparty, look-alike / address-poisoning, malicious asset. No chain call, so it fits inside an authorization or signing path.
Batch screening
Up to 50 counterparties or transfers per call with a per-item verdict and a summary: periodic customer re-screening, payment files, exposure sweeps.
Ask the intel
Plain-language questions over Prax's threat intelligence: counts by risk band, chain and role, latest approved alerts, record lookup by id. For analysts and agents; lists are never enumerable.
Approved threat-intel feed for the SOC
The reviewed alerts Prax pushes to webhooks: attacker wallets, malicious contracts, funding ancestry, clones: last 24 hours, newest first, cursor paging. Pull it into your SIEM, case manager or agent runbooks.
Chains: eth, bsc, polygon, arbitrum, optimism, base, avalanche. Auth: Authorization: Bearer prax_…, X-API-Key or ?key=. Full reference: REST docs · OpenAPI · MCP endpoint https://mcp.orabrain.com/mcp.

Quick start
Pick where your agents live. Claude, ChatGPT, Cursor and VS Code use the sign-in above; for code and the Messages API create a key in the portal and replace prax_live_YOUR_KEY. Inside the Prax Sovereign AI platform the tools are already there.
Inside the Prax Sovereign AI platform nothing to paste: the platform's agents and apps call Data Services natively, on your own hardware, with no external model calls and no data leaving your environment. Banks, payment providers and digital-asset institutions run it on-premises or air-gapped, with the premium applications (payment fraud, investigation, source tracer, contract audit, ...) and traditional rails + digital assets under one policy engine.

Prax Sovereign AI platform: the full companion
Banks, payment providers and digital-asset institutions run the complete Prax platform: a sovereign AI that reasons over your data on your own hardware: on-premises or air-gapped, no external model calls: with premium applications across traditional banking rails and digital assets, more chains and custom quotas. Data Services are built in; the same agents that answer your analysts call them natively.

Questions
Where does the intelligence come from?
Prax's own detection pipelines (contract scanning, chain monitoring, deployer and funding analysis), the sanctions lists Prax tracks (OFAC, UN and others), partner reputation data and human-reviewed alerts. Responses carry scores, labels and references — never the detection logic.
Is anything I send stored?
Requests are metered (key, tool, latency, size) for quotas and billing. Addresses, hashes and names you look up are not added to any list and are not shared.
Is this only for crypto only?
No. The public API tools cover digital-asset counterparties, transactions and transfers plus sanctions name screening, which any financial institution needs. Traditional payment rails (cards, ACH, wires, SWIFT), payment-fraud decisioning and the investigation applications are part of the Enterprise platform.
How is this different from a chain-analytics suite?
It is built for your systems and agents: a pre-authorization verdict with reasons, a name-screening tool, a plain-words search, and MCP out of the box. It is not a case-management UI, and it does not execute transactions on a fork.
Can my auditor or regulator rely on the output?
Every answer carries its reasons and references (list, alert, hop, timestamp), which is what examiners ask for. The output is intelligence to support your decision, not a legal determination — see the Terms.
Can I run it in my own environment?
Yes — the Enterprise platform runs on your own hardware, air-gapped if required, with no external model calls. Talk to us.
