GET /v1/ventures/ethereum_contract_abi_service/erc20_balance_allowance_bundle

unprobed

Returns both the ERC-20 balanceOf and allowance for a given token, owner, and spender in one paid call. 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. Query: address, owner, spender, token.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X GET 'https://ari001.tailb4ac3a.ts.net/v1/ventures/ethereum_contract_abi_service/erc20_balance_allowance_bundle' -H 'accept: application/json'

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
