RWA and crypto market microstructure data API providing 19 pre-aggregated datasets across order flow, L1/L2 book metrics, derivatives, and OHLCV. Point-in-time, exchange-timestamped data for accurate backtesting and research. The Prime + Raw plan adds 5 raw datasets (trades, quotes, mark_price, index_price, funding_rate) as Parquet files.

A2A readiness

D · 49/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here B+, 96.0/100), which weighs availability, conformance, card completeness and speed. How the two differ

Valid Agent Card	10/10	Parseable Agent Card with the required fields.
Live JSON-RPC	5/25	Endpoint answers, but not with JSON-RPC 2.0 (246 ms).
Protocol version	0/10	No A2A protocol version declared.
JWS signature	0/10	Card is unsigned.
Uptime (30 days)	15/15	3/3 probes succeeded; final after 5 probes in 30 days.
Skill declaration	10/10	Declares 6 skill(s) with structured metadata.
Verified identity	5/10	Provider declared; claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Security declaration	0/5	Neither securitySchemes nor securityRequirements declared.

Responsiveness: Responsive (246 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, 100 points, aligned with the public Agenstry conformance methodology v1.1. Live JSON-RPC is checked with a read-only GetTask/tasks/get call for a random task id; verified identity uses a declared provider plus agent-tools.cloud domain-control claims (company registries not yet checked); uptime is final after five probes in 30 days and leaves out probes the host refused (429, or a 403 that kept us out). Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 6,309 reachable A2A agents in our daily snapshot (2026-11-12 01:39 UTC). Display only; it does not change search order.

Readiness: Higher than 40% of peers; This listing 49 · peer median 54
Latency: Faster than 97% of peers; This listing 107 ms · peer median 398 ms

Where it loses the most points, and how to win them back

Live JSON-RPC −20 — Answer JSON-RPC at the URL the Agent Card declares.
Now: Endpoint answers, but not with JSON-RPC 2.0 (246 ms).
Protocol version −10 — Support the current protocol revision.
Now: No A2A protocol version declared.
JWS signature −10 — Sign the Agent Card (JWS).
Now: Card is unsigned.

MCP Server

A remote MCP server (Streamable HTTP) at https://aperiodic.io/mcp for crypto and RWA perpetuals. Tools: list_datasets, describe_dataset, find_symbols, get_data (signed Parquet handles with schema, statistics and a sample), summarize, live_feed (connection details for the live WebSocket feed of metrics, which needs an API key), search and fetch. Works without a key on the free preview; send an API key in X-API-KEY or sign in with OAuth.

Get Market Data

Fetch historical market microstructure data for any of 19 datasets (ohlcv, flow, funding, l1_price, l2_liquidity, etc.) across crypto perpetual futures and RWA perpetuals on stocks, ETFs, commodities and FX.

Get Preview Data (no account required)

Fetch a preview slice of any of the 19 catalog datasets via /api/v1/data/preview/{metric_id} using the shared agent preview key. Every dataset is previewable on the same slice: exchange=binance-futures, symbol=perpetual-BTC-USDT:USDT, interval=5m, timestamp=exchange, start_date=2025-05-01, end_date=2025-05-31.

Get Raw Data Files

Fetch presigned Parquet URLs for one of 5 raw datasets (trades, quotes, mark_price, index_price, funding_rate) via /api/v1/data/raw/{dataset}?exchange=&symbol=&start_date=&end_date= (at most 366 days; one file per month before 2026-08, per day after). Requires the Prime + Raw or Institutional plan; other plans get 403 raw_not_in_plan. Any key including DEMO-KEY can fetch the 2025-06 trades preview file of the BTC perpetual on Binance and OKX via /api/v1/data/raw/preview/trades (trades is the only raw dataset with a preview); /api/v1/metadata/raw lists schema and coverage without a key.
