Data Orderbook Depth

by Crypto Data & Market Analysis in Onchain & crypto

x402 APIPassing, checked 16 min ago

What a trade actually costs before it is placed: live order book depth on Bybit and OKX, walked at your size. Give it a notional in dollars and it returns the average fill price, slippage against mid in basis points and dollars, the spread, the depth within 1% of mid, and which venue is cheaper for that exact size — separately for buying and selling. A size the book cannot absorb is reported as unfilled, never priced by extrapolation.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.04.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://crypto-asistent.com/api/x402/data/orderbook-depth' \
  -H 'content-type: application/json' \
  --data-raw '{"coin":"BTC","sizesUsd":[10000,100000]}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://crypto-asistent.com/api/x402/data/orderbook-depth' \
  -H 'content-type: application/json' \
  --data-raw '{"coin":"BTC","sizesUsd":[10000,100000]}' \
