Compute mid price from bid/ask top-of-book levels. Call when you have L1 bid and ask and need a mid for marks. Returns mid, spread_abs, and spread_bps as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Html Meta Refresh Parse: Html Meta Refresh Parse parses bounded meta-refresh delay and target URL from bounded caller-supplied values without an external provider. Call Html Meta Refresh Parse before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Html Meta Refresh Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, statel…

CSV Numeric Profile: CSV Numeric Profile profiles parseable numeric counts and bounds for selected CSV columns from bounded caller-supplied values without an external provider. Call CSV Numeric Profile before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Numeric Profile as versioned deterministic JSON. Price: $0.001 USDC…

Screen untrusted text for common cross-site scripting signals without echoing it. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible…

JSON Array Length Check: JSON Array Length Check checks selected array fields against caller item-count bounds from bounded caller-supplied values without an external provider. Call JSON Array Length Check before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Length Check as versioned deterministic JSON. Price: $0.…

Takes an audio or video file by URL or inline base64 and returns the transcript: the full text, every word with start and end time and its own confidence, the utterances and paragraphs the recogniser separated, and the detected language with its confidence where no language was specified.

Takes a video by URL or inline base64 and reports where the picture changes. FFmpeg measures the difference between consecutive frames; every jump above the threshold starts a new scene, and the answer lists each scene with start, end, duration and the fraction of the running time it covers, plus the raw detection score positions.

Returns network-wide totals: total x402 events, service count, and a UA classification breakdown (agent vs browser vs bot). Use it to benchmark your service's agent-traffic share against the network.

Hotel photos — a hotel's photo library by property token, grouped into themed sections with full-size URLs, thumbnails, dimensions & paging.

Hotel details & rates — one hotel's full profile by property token: address, phone, per-booking-site nightly & total rates, rooms, amenities & review breakdown as clean JSON.

Build a bounded exponential retry delay schedule with a hard delay cap — call when configuring exponential backoff before calling a flaky dependency. Use before side effects when composing multi-step agent jobs—the same loyalty/workflow demand band agents already pay for on Bazaar, but fully local. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim…

Combine success rate, latency score, and saturation into an ops health band — call when combining success, latency score, and saturation into a band. Use for SRE/ops math agents buy from broad utility catalogs: SLA, error budget, success rate, and health scores with zero upstream cost.

Tracks S-1, 424B, 8-A12B, CERT, EFFECT and review correspondence. Stage-filtered to drop trading-stage housekeeping noise — a 'what's happening in crypto ETF regulation' heartbeat for monitoring agents.

Crypto ETF Sentinel — Crypto ETF AUM leaderboard: top-N US spot crypto ETF issuers ranked by assets under management (or another XBRL TIER1 concept). See the largest Bitcoin, Ethereum and other crypto ETFs by fund size, from daily-updated XBRL facts.

Crypto ETF Sentinel — Crypto ETF fee comparison: current expense ratio for every trading US spot crypto ETF, sorted cheapest first — compare fees and find the lowest-cost Bitcoin, Ethereum and other crypto ETFs. Outlier-capped at 200bps to drop bad XBRL extractions.

Crypto ETF Sentinel — Under-review US spot crypto ETF issuers stalled 148+ days without comment-letter activity (a proxy for SEC inactivity). Sorted by days-since-last-activity descending. Long stalls historically correlate with withdrawal risk.

Crypto ETF Sentinel — Week-over-week pipeline delta for US spot crypto ETFs: change in stage counts, filings-7d, under-review count vs. a prior daily snapshot. Returns 404 (no charge) when no snapshot exists for the requested ``days_back``.
