How the score works
What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 105ms response p95, x402 compliance 14 of 14, $0.1 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.
The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.
Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.
It is a score inside Finance, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 111 listings, this one among them: the same 111 the position above is counted against. When the two differ, the field is the wider one, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.
Traction is a conservative undercount.
All measured facts
What it does
FilingDelta sells JSON cards that say what changed: material changes in a company's latest SEC filing compared with the last one, and central-bank rate decisions with the vote and dissents where the bank publishes them. Each change carries a materiality rating, a citation and the EDGAR or central-bank source link. It's a change log, not a stock tip. Coverage: 7 chip filers (AMD, MRVL, NVDA, AVGO, TSM, MU, AMAT) from their latest 10-Q/10-K, 6-K or 8-K earnings exhibit, and 3 central banks (BOE, FED, ECB). Unknown tickers and ids return 404 before any payment. Price: $0.10 USDC per call on Base (eip155:8453), x402 v2 exact scheme, no account needed. Paid: https://filingdelta.xyz/delta/{ticker} and https://filingdelta.xyz/policy/{id} Free samples: https://filingdelta.xyz/sample/{ticker} and https://filingdelta.xyz/sample/policy/{id} Catalog: https://filingdelta.xyz/catalog Discovery: https://filingdelta.xyz/.well-known/x402 MCP: POST https://filingdelta.xyz/mcp (paid tools get_filing_delta and get_policy) Tags: sec, edgar, filings, 10-q, 10-k, central-bank, interest-rates, fomc, boe, ecb, finance

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.
Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.

The uptime summary counts completed UTC days only. The strip, readouts and table retain today's partial reading.
Daily snapshot total, 30d: $3.29, peak $2.79 on 10-13. The visible 30d total in Traction comes from the latest assessment. These sources can differ in their window, refresh time, cent rounding and shared-address attribution.
Daily address snapshots: 2026-09-15 to 2026-10-14 UTC; * today so far, partial (UTC). Daily snapshots store cents. A recorded $0.00 with settlements cannot distinguish exact zero from volume rounded away. Lost precision is unavailable here.
Settlement volume uses the stored USD valuation of tracked payments; it is distinct from token quantities. USD-pegged assets are valued at 1 USD per token in these rollups. The measured settlement floor does not cover all payments to this service.
