## How to pay

Payment method: MPP tempo.charge (USD stablecoin on Tempo). Cards are not accepted yet.

- Tempo CLI (recommended): install https://tempo.xyz/SKILL.md, then:
  tempo request -X POST --json '{"asin":"B01MDTVZTZ"}' https://amazon.lightanchor.ai/v1/amazon/product
- mppx SDK: wrap fetch with Mppx.create() from the mppx npm package; 402s are paid automatically.
- AgentCash: npx agentcash fetch https://amazon.lightanchor.ai/v1/amazon/product --method POST --body '{"asin":"B01MDTVZTZ"}'

## Rules

- Malformed ASINs return 422 BEFORE payment settles: you are not charged for typos.
- Sending {} charges the tier price and returns a sample response (use the $0.05 tier to inspect output shapes).
- If an upstream fetch fails after payment settled (rare), email sangha@lightanchor.ai with your Payment-Receipt header for a refund.
