Quote 3rd-party transaction & payment insurance

Machine-to-Machine Conformance API · quote-3rd-party-insurance

$0.005 / call 3 free calls/day No signup

Compare insurance quotes from underwriters registered in the open referral directory (coverage for transaction, smart-contract, trade-credit, and BEC wire-fraud risk). Returns zero quotes until an underwriter has self-registered; this gateway never underwrites risk itself.

Honest Scope Guarantee

Open referral directory connecting buyers and agents to underwriters that have self-registered (the directory ships empty; registration is not vetting). Code402 never holds float or takes balance-sheet risk; issues cryptographic POL-1 certificates for bilateral peer-to-peer policies on Base L2.

Quickstart & Execution

cURL (20 Free Calls/Day • Zero Authentication Required)

curl -X POST https://api.code402.dev/v1/tools/quote-3rd-party-insurance/call \
  -H "content-type: application/json" \
  -d '{"amount_usdc":50000,"coverage_type":"commercial_trade_credit"}'

No API key needed for the free daily tier. When daily quota exhausts, the endpoint replies with HTTP 402 Payment Required specifying the exact USDC amount. Machines sign an EIP-3009 transfer on Base L2; human engineers buy card credits. Every paid execution returns a cryptographically signed XDR-1 receipt for zero-knowledge audit trails.
