Prompt Injection Scan

by Delx Prompt Injection Scan in Onchain & crypto

x402 APIPassing, checked 4 h ago

Screen untrusted text for prompt-injection and tool-coercion signals before an agent consumes it. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base or Solana. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

Call it from code

The curl command shows the payment challenge.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://api.delx.ai/api/v1/x402/prompt-injection-scan' \
  -H 'content-type: application/json' \
  --data-raw '{"text":"example"}'

# 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://api.delx.ai/api/v1/x402/prompt-injection-scan' \
  -H 'content-type: application/json' \
  --data-raw '{"text":"example"}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode

We don't show code that pays this service: its listing contains instructions aimed at AI agents.
