X402 Chain Reads V1 Base Balance Code Bundle

by Base Balance Code Bundle in Onchain & crypto

x402 APIFailing, checked 15 h ago

Returns base_eth_getbalance and base_eth_getcode results in one paid call, keyed by each part's name. Base bundle of the declared parts. Returns: each named part service's own result, in one paid call, keyed by the part's name -- exactly what each part returns when bought alone; the call succeeds only when every part answers. It takes the union of the parts' query parameters.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.006.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://ari001.tailb4ac3a.ts.net/v1/ventures/x402_chain_reads_v1/base_balance_code_bundle?address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045'

# 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 - 'https://ari001.tailb4ac3a.ts.net/v1/ventures/x402_chain_reads_v1/base_balance_code_bundle?address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045' \
