A pair on Arc as executed against USDC: volume-weighted rate, range, the rate by trade size, and where the volume traded. ?symbol=EURC (default), cirBTC, WETH or CRA.

Status, sender, recipient, fee in USDC and every ERC-20 transfer in an Arc transaction, with symbols and human-readable amounts.

European Central Bank reference rates against a base currency, latest or on a past date. A daily reference, not an executed price: for that see /v1/paid/fx/execution.

All pairs the collector prices against USDC (cirBTC, WETH, EURC, CRA) in one call: last executed price with its age in seconds, hourly volume-weighted price with the 5th-95th percentile range, trade count, volume, and 24h change. From real swaps on Arc, not a quote.

The price of USYC (Circle's tokenized money market fund of short-term US Treasuries) from the oracle its Teller mints and redeems at, the yield its price shows over 7 and 30 days as a yearly rate, every published price on Arc, and the supply on Arc.

Convert an amount between two currencies at the European Central Bank reference rate, latest or on a past date.

Name, symbol, decimals and total supply of any ERC-20 on Arc, read from the contract at the latest block.

CRC-16 over the input payload in one of several standard variants (ccitt-false, xmodem, modbus, ibm; default ccitt-false). Returns the checksum as an unsigned integer and 4-digit hex. Non-cryptographic.

CRC-32 (IEEE 802.3 polynomial, as used by zip, gzip and PNG) over the input payload. Returns the checksum as an unsigned integer and 8-digit hex. Non-cryptographic — for error detection only.

Every canonical setup evaluation for a given day, filterable by state (fires / boundary / silent / first_ever), factor family, or asset. Includes z_scores per metric, distance_to_trigger, confidence. Distance is measured in sigma — positive = past threshold, negative = short of threshold. Boundary + first_ever states are the highest-signal reads. Applicable across the CRYPTYX 200+ asset coverage universe (BTC, ETH, SOL, top-cap + long-tail); backtested scope is the 33-asset curated slice.

Canonical setup catalog list — 150 founder-approved multi-metric compositions across 8 factor families + cross-family fades. Filter by factor_family (TR/EFF/VOL/FLOW/FUT/OB/OPT/CORR/CROSS_FAMILY), tier (1-5), direction (long/short/neutral), asset (in applicable_assets), or durability_class (structural for 90d+ high-Sharpe, tactical for small-sample, hybrid for the rest). Each setup ships display_name, composition, primary_horizon, backtest snapshot pointer. The shipping surface — not a raw metric database. Applicable across the CRYPTYX 200+ asset coverage universe (BTC, ETH, SOL, top-cap + long-tail); backtested scope is the 33-asset curated slice.

Canonical harness tear-sheet — one call returns totals (fires / boundary / silent / first-ever), top-5 fires by confidence, first-ever prints (5-year rarity), boundary watchlist (near-fire ranked by distance-to-trigger), and silent fade setups. Every setup carries plain-English composition (via ref.metric_display_labels) so responses never leak raw metric_id strings. Priced cheap so polling patterns stay economically viable — every MCP skill instructs Claude to call this FIRST as the canonical orientation. Scope: apex (BTC/ETH/SOL default), all (33-asset curated universe), or asset:{SYMBOL} for single-asset lens.

Near-fire setups ranked by distance-to-trigger DESC (closest to firing first). Primary monitoring surface for autonomous agents — cheap to poll at 15-30 min intervals to detect when a queued setup is about to fire. Distance in sigma; 0.2 means one metric is 0.2σ from its threshold. Cheaper than polling /api/v1/harness/evaluations when you only care about near-fires. Applicable across the CRYPTYX 200+ asset coverage universe (BTC, ETH, SOL, top-cap + long-tail); backtested scope is the 33-asset curated slice.

First-ever fires — setups that fired for the FIRST TIME in prospective history. Rarest, highest-signal events in the canonical catalog. A setup with state = first_ever has never fired before since it was added. Historical backtest reflects behaviour on ADJACENT setups or partial configurations, not this exact combo — treat as structurally important context, not directional recommendations. Applicable across the CRYPTYX 200+ asset coverage universe (BTC, ETH, SOL, top-cap + long-tail); backtested scope is the 33-asset curated slice.

Service health probe — build version, last pipeline run, current signal/composite/asset counts. Sub-second, no DB writes. The cheapest end-to-end pay-per-call check before issuing real queries.

Arbitrary trigger definition — POST any {type: z_score|z_differential|composite, ...} predicate and get the full institutional evidence envelope back. 5-year backtest, Sortino, max drawdown, profit factor, walk-forward IS/OOS, regime context, rolling hit rates. Enterprise tier because every request runs a live backtest (no cache). The extensibility endpoint: anything expressible in Metric Slicer becomes a triggerable institutional-grade primitive. Backtests run over the CRYPTYX 200+ tracked digital assets — BTC, ETH, SOL, top-cap + long-tail coverage.

CVE lookup and vulnerability search — resolve a CVE ID via OSV and return summary, severity, affected packages, and references for agent triage.

Look up a CVE by id, or search CVEs by keyword or product: the NVD description, CVSS severity and vector (v4.0, v3.1, v2), CWE weaknesses, affected products and versions (CPE), and reference links, joined with the EPSS exploitation probability (next 30 days) and whether CISA lists it as a known exploited vulnerability (date added, due date, ransomware use). This product uses the NVD API but is not endorsed or certified by the NVD.
