XRPL Microstructure

Blockchain PAYMENT-READY

payment-ready until 2026-08-20

First-party XRPL market-microstructure and safety data, served per call over x402 and paid in USDC on Base. Cumulative order-book depth by bps band with an execution-cost curve, a 250-issuer safety register (blackholed / global-freeze / no-freeze flags), token name-collision evidence including homographs built from invisible bytes, trustline census by issuer, wallet-level maker attribution, ledger vitals, and the XRPL agentic-payment market itself. Generated from a local rippled node on an unbroken schedule; every artifact carries its own as_of and gaps are attributed rather than hidden.

Pay from $0.05 to $0.75 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

compliance A (13/14): x402 v2 envelope delivered in the payment-required header

13 of 14 x402 conformance checks pass; failing: x402 v2 envelope delivered in the payment-required header. Full checklist below.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share is a concentration signal, not part of the ranking score.

REQUEST / RESPONSE EXAMPLE

An unpaid request to GET /v1/chains returns HTTP 402 with the payment terms. Settle onchain via your facilitator, then retry with the X-Payment header.

OVER TIME

All charts use the 90d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/xrpl-microstructure/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
