Response fields

Field
sstring
Symbol.
cstring
Close price, precision-normalized.
dstring (YYYY-MM-DD)
UTC day the close belongs to.
tint64 (epoch ms)
Timestamp of the close, Unix epoch milliseconds.

Reference

Close price is a string, cast before math
Why
c (close price) comes back as a JSON string to preserve exact precision. Only t is a number (epoch ms).
The trap
Math on the raw field breaks: Python raises TypeError, JavaScript + silently joins the strings instead of adding.
Python
close = float(data["c"])
JavaScript
const close = Number(data.c);
cURL / jq
Cast in jq too: jq '.c | tonumber'
Historical bars differ
Bars from /v1/hist/* already return t, o, h, l, c, v as plain numbers, do not cast those.
