What the records say

This is a filter over recorded facts, shown in name order. It is not a recommendation and nothing here is ranked. Not recorded means this site holds no record, never that the API lacks it.

All 29 records are listed, in name order.

Side by side

Tick Add on up to three records above and they appear here in columns, drawn from the same records. Columns are in name order.

How each answer is decided

No answer comes from a program reading meaning into a sentence. Each is a structured field, a record that exists, or a row of the capability facts register: a person's reading of the record's own sentence, entered only where its words settle it, with the reason shown in the side by side view and on the capability's page. A reading takes its status from the sentence it was read from, so a reading of an unverified sentence is unverified. The counts are of the 29 records on this site.

A demo environment

Read from the record's own sentence about demo or sandbox access. A person read the sentence and entered yes, partial or no in the capability facts register only where its words settle it, with the reason and the scope printed. A demo of a trading platform that is not said to work with the API is partial, never yes. A sentence that settles nothing stays at not recorded.

14 recorded as yes and verified, 10 partial, or yes but not verified, 2 not recorded, 3 recorded as no. Demo or sandbox, record by record

Streaming of any kind

Read from the record's own sentence about streaming: data pushed over a connection that stays open. A person read the sentence and entered yes, partial or no in the capability facts register only where its words settle it. Yes here does not say what is streamed: the next two lines do.

17 recorded as yes and verified, 3 partial, or yes but not verified, 8 not recorded, 1 recorded as no. Streaming, record by record

Streaming prices, where a record says prices

Yes or partial only where a record says in words that prices or market data are streamed: the record's sentence about streaming, or an endpoint record for a price stream, cited beside the cell. A record that describes streaming without saying what is streamed stays at not recorded. A record that says there is no streaming is a no.

15 recorded as yes and verified, 3 partial, or yes but not verified, 10 not recorded, 1 recorded as no. Streaming, record by record

Streaming account updates, where a record says so

Yes or partial only where a record says in words that account updates are streamed, such as orders, positions, balances or executions: the record's sentence about streaming, or an endpoint or error record for an account stream, cited beside the cell. Anything else stays at not recorded, except a record that says there is no streaming, which is a no.

12 recorded as yes and verified, 0 partial, or yes but not verified, 16 not recorded, 1 recorded as no. Streaming, record by record

A Python library, official or community

The same cell as the Python library table, so the two surfaces give one answer: yes means the record lists at least one library whose language field names Python, each shown as official or community as the record marks it. A record that lists no Python library is not recorded, which is not evidence that none exists.

14 recorded as yes and verified, 0 partial, or yes but not verified, 15 not recorded, 0 recorded as no. Python library, record by record

Its own API, not only a platform

Read from the broker record's nativeApi field: true is yes and false is no. Where the field is empty, a row of the capability facts register decides it if the record's sentence about access settles it, and otherwise it is not recorded. A platform record is itself an API, so the question does not apply to it.

14 recorded as yes and verified, 1 partial, or yes but not verified, 0 not recorded, 6 recorded as no, 8 where the question does not apply. Own API, record by record

An MCP server

Yes means the MCP server register holds a server whose owner is this record, official or community, and the cell says which. A server that was looked for and not found is still not recorded.

14 recorded as yes and verified, 0 partial, or yes but not verified, 15 not recorded, 0 recorded as no. The MCP server directory

Documented rate limits

Yes means the limits register holds at least one limit record for it, read on the source shown. With no limit record, a row of the capability facts register decides it where a record settles it: no where the record says no limit is published, which is not a statement that there is no limit, and partial where a limit is documented for part of the API or is only served at runtime. Any other sentence stays at not recorded.

13 recorded as yes and verified, 3 partial, or yes but not verified, 8 not recorded, 5 recorded as no. Published rate limits, record by record

REST order placement recorded on this site

Yes means this site holds at least one endpoint record for it whose method and path place an order or open a position. Not recorded means this site has documented none. It says nothing about what the API can do.

10 recorded as yes and verified, 0 partial, or yes but not verified, 19 not recorded, 0 recorded as no. Place an order: the endpoints, broker by broker

Fits as recorded

Every fact you chose is recorded as yes, on a record verified at its source.

May fit: partial or not verified

Every fact you chose is recorded as yes or partial, but at least one is only partial, or is a yes that rests on a record that is unverified or has conflicting sources. Each cell says which.

Not recorded here

This site holds no yes or no for at least one fact you chose. That is a gap in this dataset, not a no.

Does not fit as recorded

A record on this site says no to at least one fact you chose, or the question does not apply to this kind of record.
