Position Health

by Position Health Check in Onchain & crypto

x402 APIPassing, checked 4 h ago

The post-trade check everything else skips: given a token, your position size and (optionally) entry price, returns live price & P&L, whether the position can still be EXITED at that size, and the token's current rug score — combined into a healthy / watch / exit_now verdict with reasons. The risk that changes after you buy is exactly the risk holders miss.

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 'https://402.com.tr/api/x402/position-health?address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&entryPrice=0.0012&size=1000'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
