All coin ids (paged)

The complete list of tracked coins (~18k) as {id, symbol, name}, paged: `page` + `perPage` (1-500, default 250). Send GET /api/coins-list with no required fields (5 optional) and pay $0.005 per call over x402 or MPP (there is no free tier). It returns a JSON object with source, fetchedAt, cached, page, perPage and 5 more.

`includePlatforms: true` adds each coin's contract address per platform; `platform` (e.g. base, solana, ethereum) keeps only coins with a contract there; `symbol` keeps one ticker (exact, case-insensitive) across all its namesakes. For bulk id resolution, building a local symbol map, or enumerating every token on one chain; for a single lookup use coin-search. The upstream list is fetched once and cached in-process for 10 minutes, so paging through it costs the shared quota one call.

Parameters

Example request

curl -i "https://agent402.tools/api/coins-list?symbol=usdc&includePlatforms=true"

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

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

Errors and behavior

• Every field is optional. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example.
• 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 (Authorization: Bearer a402_...) also pays it.
• A POST with a JSON body to /api/coins-list is served as this GET, with the body as the input.
• 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 { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

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/coins-list?symbol=usdc&includePlatforms=true");
