# 1) Free health
curl -sS "$BASE/health"

# 2) Free static example of a successful response (USDC snapshot shape)
curl -sS "$BASE/v1/examples/token-check" | head -c 400; echo

# 2b) Free static batch example (USDC+USDT shape; no payment)
curl -sS "$BASE/v1/examples/token-check/batch" | head -c 400; echo

# 3) Unpaid probe — expect HTTP 402 + PAYMENT-REQUIRED header
curl -sS -D - -o /dev/null \
  "$BASE/v1/token-check?mint=EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"

# 4) Unpaid batch probe (up to 5 mints) — 402; amount 10000 µUSDC ($0.01)
curl -sS -D - -o /dev/null \
  "$BASE/v1/token-check/batch?mints=EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v,Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB"

Then pay with any x402 v2 Solana exact client against the PayAI facilitator and retry the same GET with the payment header. Single amount is 5000 µUSDC ($0.005); batch is 10000 µUSDC ($0.01) for 1–5 mints.

What you get (paid)

Direct Solana mainnet account reads only:

mint / freeze authority (active or renounced)
Token-2022 risk extensions (permanent delegate, transfer hook, transfer fee, pausable, non-transferable, default-frozen, mint close)
metadata mutability
top-holder concentration when RPC allows
heuristic riskLevel + flags[]

See free sample JSON at /v1/examples/token-check (single) and /v1/examples/token-check/batch (batch envelope).

Free mint preflight (no payment, no RPC)

Validate base58 shape before paying — catches typos without a 402 round-trip:

curl -sS "$BASE/v1/mint-preflight?mint=EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"
curl -sS "$BASE/v1/mint-preflight?mint=not-a-mint"   # expect HTTP 400

Known issuer assets (mint/freeze authority expected): USDC, USDT, PYUSD, USDS, EURC — still pay for a live check.

MCP (Streamable HTTP) — agent clients

Same prices as HTTP. PayAI Bazaar indexes MCP tools token_check and token_check_batch on this origin.

# Unpaid paid-tool call → payment-required (x402) with bazaar MCP extension; settle then retry.

Use an x402-capable MCP client (e.g. @x402/mcp + Solana exact scheme) against the PayAI facilitator. HTTP routes above remain available if you prefer REST.
