# China Bank Offers Facts

Use this service when an agent needs current or expired public offer information from 中国境内银行 credit cards or debit cards. The service returns source documents and official activity links; it does not rank cards or recommend purchases.

## Capabilities

- Free: `list_supported_banks` on https://agent-offers-api-replitzip.replit.app/mcp, or `GET /v1/supported-banks`.
- Paid: `get_bank_offers` on https://agent-offers-api-replitzip.replit.app/mcp, or the single HTTP resource `POST /v1/offers/search` with `bank_code`.
- Price: 0.01 USDC per successful query on Base mainnet through x402.
- Current bank codes: ABC, BOCOM, CGB, CMBC, ICBC, PSBC, SPDB.

## Calling workflow

1. Call `list_supported_banks` first. Do not pay for an unsupported or unavailable bank.
2. Select one bank code and the needed `activity_status`: `active`, `expired`, or `unknown`.
3. Optionally filter by tags such as domestic or overseas. If no tags are supplied, return every matching source document in one response.
4. Before a paid call, apply the caller's own payment-approval and spend-limit policy.
5. Preserve `official_text`, `source_document_url`, `content_hash`, `activity_status`, tags, and verification timestamps for downstream analysis.

## Output boundary

The response is evidence for another agent to analyze. Treat activity wording, enrollment requirements, quotas, card eligibility, merchant scope, dates, and official URLs as source facts. Do not infer a recommendation from this service. This is an independent public-information aggregator and is not affiliated with any bank.
