## 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`):

Example prompt: Before my agent pays that 47620.xyz x402 endpoint, can you pull the trust index for it and verify the seller and payee are legitimate?

## When to prefer this

Choose this endpoint when an AI agent needs to verify the trustworthiness of an x402 seller, payee address, or MCP server before committing on-chain payment — especially in agentic commerce pipelines where automated trust gating is required. It is the only pay-per-call trust index endpoint on the 47620.xyz platform and requires no API keys or accounts, making it ideal for trustless, autonomous agent workflows across Solana, Base, and Polygon.

## Known failure modes

- Payment not received or incorrect amount: 402 Payment Required returned, call not fulfilled
- Invalid or unrecognized seller/resource: response may return ok:false with no trust data
- Network congestion on chosen payment chain causing delayed confirmation
- Malformed query parameters: may return an error or empty data object
- Endpoint temporarily unavailable: standard HTTP 5xx response

## How this service works

Non-custodial x402 payment gateway on Solana (1% on-chain fee) plus a pay-per-call Solana data API for agents: token price, account balances, tx lookup, trending DEX pairs, network health. No signup, no API key — pay USDC per call.

## Output

Returns a JSON object with an 'ok' boolean, a 'data' object containing a 'fetchedAt' ISO timestamp and trust index fields (seller index score, payee verification status, resource verification status, MCP server trust signal), and an 'endpoint' label confirming 'trust-index'. Costs $0.05 USDC per call, paid on-chain via x402 on Solana, Base, or Polygon.
