Try all five services.

Runnable Python 3.11+ and curl examples. Two free tools; three reports at 0.02 USDC on Base each. The example client never signs and never submits a payment unless explicitly run with --send.

Try the receipt report without funds

Run the live public-chain example → or read its JSON directly. This is one fixed historical public Base USDC transfer, cached for up to five minutes. It is not your payment and is not a funded checkout test.

python3 examples/client.py demo
curl --fail-with-body https://coins.zhidun.ai/demo/usdc-receipt.json

Discover and inspect without funds

python3 examples/client.py catalog
python3 examples/client.py cost
python3 examples/client.py calldata
python3 examples/client.py challenge --service bsc-reconcile
python3 examples/client.py challenge --service usdc-receipt
python3 examples/client.py challenge --service erc20-allowances

The cost fixture models a small loss after supplied costs. The call-data fixture interprets an illustrative maximum ERC-20 approval. A 402 challenge is payment information, not a charge.

Use real input for a paid report

Already using AgentCash? Read the merchant receipt workflow → for discovery, schema inspection and safe purchase recovery.

Choose an input template: BSC receipt, Base USDC receipt or allowances. Replace every placeholder and declare the actual eligible customer's country. Preparation saves an exact request and private retrieval key; an approved compatible buyer separately authorizes payment. Never submit a wallet private key or seed phrase.

The walkthrough covers authorization, explicit submission, recovery and response interpretation. Preserve one original body, key and authorization across retries. Creating a new payment to fix a timeout can charge twice.

Know the boundaries

Paid services are for actual eligible customers outside mainland China, where lawful. Public docs and deterministic free tools are accessible. Network reachability does not establish customer eligibility. All reports are read-only evidence or calculations. Base L2 depth is not L1 finality; ABI decoding is not simulation; allowances are not a safety audit.

Public alpha. Dependency readiness is not a service-level guarantee. No independently verified paying customer result yet. Read the service terms and Agent skill.
