Returns a structured decision procedure (accept, hold-with-conversion-cap, or reject) for an agent receiving an Algorand Standard Asset as payment, based on ASA risk factors like clawback, freeze, and supply controls.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability algorand-asa-payment-acceptance-screen-a71e9194
```

Example prompt: Before I accept that Algorand Standard Asset as payment, run it through the ASA payment acceptance screen and tell me whether I should accept it, hold it with a conversion cap, or reject it and demand ALGO instead — especially flag any clawback or freeze risk.

## When to prefer this

Use this endpoint when an AI agent is on the receiving end of an Algorand Standard Asset payment and needs a structured, risk-aware decision before accepting. It is specifically designed for the ASA-as-payment scenario on Algorand — prefer it over generic blockchain lookup tools when you need an actionable accept/hold/reject verdict that accounts for clawback, freeze, and supply manipulation risks unique to ASAs.

## Known failure modes

- Payment required but not provided — returns 402 with payment instructions
- Invalid or missing input object — returns validation error
- ASA metadata unavailable or unresolvable — procedure may be incomplete
- Network timeout reaching Algorand node data — stale or missing supply info
- Topic override not recognized — falls back to default decision procedure

## How this service works

Decision procedure for an agent being offered an Algorand Standard Asset as payment, the receiving side of the transaction. Inspect the ASA before accepting: clawback address present means the issuer can claw funds back after receipt, freeze address can freeze your balance, reserve and manager accounts can mint or alter supply, default-frozen requires opt-in approval, check supply and metadata. Verdict thresholds for accept, hold with conversion cap, or reject and demand ALGO. Companion to the

## Output

A structured decision brief including an accept/hold-with-conversion-cap/reject verdict, prose explanation of the decision procedure, risk factors identified (clawback address, freeze address, reserve/manager accounts, default-frozen status, supply metadata), the model used, generation source (llm, reasoning, or deterministic), and an ISO-8601 timestamp.
