Solana token prices (Jupiter)

USD price for up to 50 Solana token mints in one call from Jupiter's price API v3: price, 24h change, liquidity, decimals and the block the price was read at. Send POST /api/sol-price with the required field mints and pay $0.001 per call over x402 or MPP (there is no free tier). It returns a JSON object with count, missing, prices, source and fetchedAt.

Mints Jupiter does not price come back listed under missing rather than erroring the batch. Pass mint addresses, not tickers (resolve tickers with sol-token-search or sol-token-lookup). Keyless.

Parameters

Example request

curl -i -X POST https://agent402.tools/api/sol-price \
  -H "Content-Type: application/json" \
  -d '{"mints":["So11111111111111111111111111111111111111112","JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN","EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"]}'

Without payment this returns HTTP 402 Payment Required with the exact price for sol-price; any x402 v2 or MPP client pays it and retries.

The hosted connector at https://agent402.tools/mcp needs a payment for sol-price; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.

Errors and behavior

• mints is required. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example, so the caller can correct it.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
• Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key issued earlier (Authorization: Bearer a402_...) also pays it.
• A GET or HEAD to /api/sol-price returns the same 402 quote, so the price can be read without a body.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).

Paid call (JavaScript agent)

import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
client.setSpendControls?.(false); // keep your own spending ceiling in code
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/sol-price", {
