Filter by ?symbol and ?limit. | $0.001 | Base+ | USDC | header | since 09-07 |
| GET | / | Per-timeframe candle-level audit · MAPE and MAE broken down by 5m, 15m, 1h, 4h, 1d. From 47k+ audited candles. Filter by ?symbol. | $0.005 | Base+ | USDC | header | since 09-14 |
| GET | / | Open markets for Kronos-covered coins with vote status. | $0.005 | Base+ | USDC | header | since 09-14 |

Use ?detail=1 to include full pred_candles arrays (default: stripped · use /decision/:id for single full detail). Response includes total count for pagination. | $0.001 | Base+ | USDC | header | since 09-14 |
| GET | / | AI-powered cross-referenced digest · combines 7 data sources into insight-driven analysis. | $0.03 | Base+ | USDC | header | since 09-07 |

All timeframes by default, or filter with ?timeframes=5m,1h. $0.01 per timeframe, capped at $0.04 (20% off when requesting all 5). ?refresh=true forces GPU inference (bypasses cache) at 2x price ($0.02/TF, cap $0.08); use it with ?async=true. Sync requests requiring refresh or 3+ uncached timeframes return 409 async_required without charge. Horizon: 5m→6h, 15m→24h, 1h→2d, 4h→10d, 1d→14d. For long-running calls, use ?async=true and poll the returned job status URL. | $0.04 | Base+ | USDC | header | since 09-07 |

How the score works
What the score read on this service: status online, 99.8% uptime 30d, 231ms response p95, x402 compliance 14 of 14, $0.001 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 109 listings, this one among them: the same 109 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.
Settled via payAI ($7.53, 738 tx) and dexter ($0.63, 63 tx). Traction is a conservative undercount; first settlement seen 2026-08-31.
All measured facts
What it does
Auditable multi-asset financial forecasting for research and agent decision support. Crypto, commodities, and pre-market equities. 23 paid x402 endpoints on Base + Solana mainnet. Prices from 0.001 to 0.05 USDC per request.
Kronos Quant Signal API is a listed x402 Finance API. Captured payment terms name Base, Solana. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

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.
