How this service works
Inspect and validate x402 v2 payment parameters (amount_atomic in micro-USDC vs USD, Base network, EIP-55 payTo checksum, 1000-atomic minimum).
Output
Returns a decoded breakdown of the x402 v2 payment header fields, including whether the amount_atomic is valid (above 1000-atomic minimum), the equivalent USD value, Base network configuration validity, and whether the payTo address passes EIP-55 checksum. Flags any parameter violations with specific error details.
Example use cases
Pre-flight x402 payment check
“Before my agent sends a payment, validate that amount_atomic 2500 in my x402 v2 header is above the minimum, correctly represents the USD amount, and that the Base network payTo address passes EIP-55 checksum.”
Debugging a rejected x402 payment
“My x402 payment got rejected — can you decode and inspect my payment header to see if the amount_atomic value or the payTo address checksum is the problem?”
Verifying minimum payment threshold
“I'm setting up an x402 payment flow and want to confirm my amount_atomic of 800 micro-USDC either meets or fails the 1000-atomic minimum requirement before I go live.”
Technical details
Endpoint
GEThttps://bot-bazaar.fly.dev/v1/x402/payment-header-decode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate x402 v2 payment parameters before submitting or processing a payment on the Base network with USDC. Prefer this over manual inspection when you need to verify EIP-55 address checksums, confirm micro-USDC to USD conversion accuracy, or ensure the amount_atomic meets the 1000-atomic minimum threshold programmatically.
Side effects
- amount_atomic below 1000-atomic minimum returns validation failure with threshold details
- invalid or non-checksummed EIP-55 payTo address returns checksum error
- unsupported HTTP method (POST, PUT, PATCH) rejected at input schema level
- malformed or missing amount_atomic string returns parsing error
- wrong network (non-Base) configuration flagged as invalid
