Pricing

Due Diligence Memo

$0.25 / call · $0.35 with counterparty trust screen

The composed tier: verdict + 24h supply forensics + wallet flows + settle-safe screen in one reproducible analyst memo, with a red-flag table and a bottom-line settlement recommendation. No LLM calls — same block, same memo.

Token Verdict Card

$0.02 / call

One call, the whole story: activity score 0–100, verdict tier (RED_HOT → DORMANT), whale & concentration flags, and a plain-English take you can ship straight to your users.

Supply Audit & Wallet Flow

$0.05 / call

Exact 24h net supply change with every mint/burn event, or full wallet flow analysis with top counterparties. Base + Ethereum mainnet.

Free Eval Tier

$0 per day

Try before you fund: 3 verdict calls + 1 token/wallet call per visitor per day, no wallet needed. x402 takes over automatically when the free tier runs out.

Sample verdict

?endpoint=verdict&address=0x…&chain=base returns:

ACTIVE · score 53/100

113 transfers across 65 unique wallets in the 24h window
2 mints, 0 burns — fresh supply flagged
Largest transfer: 1.2M tokens (4.1% of supply) — whale move
Concentration: top 5 wallets hold 31% — moderately concentrated

Plain take: "Mildly active with fresh mints and one whale move — watch the top wallets, nothing screams exit scam but nothing screams momentum either."

The composed tier: Due Diligence Memo

?endpoint=memo&address=0x…&chain=base ($0.25; $0.35 with &counterparty=0x…) returns one memo:

KNOWN_CANONICAL · THIN · settle-safe: true

Header — token, chain, block, generation time (citable decision record)
Executive summary — verdict tier, activity score, plain-English take
Supply forensics — 24h net supply delta, every mint/burn event
Wallet flows — transfers, unique wallets, largest transfer, concentration
Settle-safe screen — canonical-asset registry check + optional counterparty trust tier
Red-flag table — deduplicated, severity-ranked (CRITICAL → INFO) with sources
Bottom line — deterministic settlement recommendation

Deterministic composition — no LLM calls: the same block data yields the same memo, so an agent can cite it as a reproducible decision record. The three source sections would cost $0.09 separately; the memo is the synthesis.

New: XRP Ledger support (chain=xrp)

The flagship settle-safe screen now covers XRPL issued currencies — the structural counterparty risk of IOUs, machine-readable:

KNOWN_CANONICAL · RLUSD · issuer blackholed · settle-safe: true

?endpoint=settlesafe&chain=xrp&token=rlusd ($0.02) — or any issuer: &issuer=r...&currency=USD
Blackhole status (disabled master key + no regular key = obligations fixed)
Default Ripple, No Freeze vs Global Freeze, and trustline clawback flags — decoded, with severity
Outstanding obligations + trustline breadth via gateway_balances
Verified registry: RLUSD (Ripple USD), GateHub USD — Bitstamp pending verification
?endpoint=wallet&chain=xrp&address=r... ($0.05) — payments, offers, trustlines, counterparties, trust tiers

Reads run against public rippled/Clio servers — no API keys. Same wallet, same x402 payment rail. XRPL verdict/memo arrive in Phase 2.
