Tools, public data and official Mexican data for AI agents, paid per call with x402.
Tlacuilo is an HTTP API (and an MCP server) with 35 tools that an agent can call without an account, an API key or a subscription. Every endpoint answers 402 Payment Required with its price; the agent pays a few cents in USDC on Base or Solana using the x402 protocol and gets the answer in the same request. Prices run from $0.001 to $0.05 per call.
https://tlacuilo-jet.vercel.app/api/v1https://tlacuilo-jet.vercel.app/api/v1https://tlacuilo-jet.vercel.app/mcphttps://tlacuilo-jet.vercel.app/openapi.json · x402 discovery: https://tlacuilo-jet.vercel.app/.well-known/x402 · https://tlacuilo-jet.vercel.app/llms.txtThis repository holds the documentation and runnable client examples (examples/). The server itself is not open source.
Agents are good at calling tools and bad at signing up for things. x402 turns payment into an HTTP handshake: the server says what it costs, the client signs a USDC transfer, a facilitator settles it, and the response comes back. No dashboard, no keys to leak, no monthly minimum. Tlacuilo wraps sources that are useful to agents but awkward to reach (SEC EDGAR, OpenAlex, ClinicalTrials.gov, the Federal Register, Polymarket, OSV, RDAP, DNS, and official Mexican sources such as SAT, Banxico, INEGI and CONASAMI) behind one consistent, paid-per-call interface.

The Payment-Required header is base64 JSON (x402 v2). Decoded, it contains the resource description, the accepts array with one entry per network (scheme exact, network as a CAIP-2 id, USDC asset, amount in atomic units, payTo address, timeout) and the Bazaar discovery block with the input schema and an output example:

"amount": "3000" is 0.003 USDC (6 decimals). The catalog at /api/v1 lists the same prices in dollars.
@x402/fetch)import { x402Client, wrapFetchWithPayment, decodePaymentResponseHeader } from "@x402/fetch";
import { registerExactSvmScheme } from "@x402/svm/exact/client"; import { createKeyPairSignerFromBytes } from "@solana/kit"; import { base58 } from "@scure/base";
const signer = await createKeyPairSignerFromBytes(base58.decode(process.env.SOLANA_SECRET_KEY)); const client = new x402Client(); registerExactSvmScheme(client, { signer }); // Solana mainnet, USDC const fetchWithPayment = wrapFetchWithPayment(fetch, client);
const res = await fetchWithPayment("https://tlacuilo-jet.vercel.app/api/v1/banxico/fix"); console.log(await res.json()); // { serie: "fix", fecha: "...", valor: ... }
const receipt = res.headers.get("PAYMENT-RESPONSE"); // settlement details, incl. tx signature if (receipt) console.log(decodePaymentResponseHeader(receipt));
npm i @x402/fetch @x402/svm @solana/kit @scure/base
To pay on Base instead, register the EVM scheme with a viem account:
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts"; const client = new x402Client().register("eip155:*", new ExactEvmScheme(privateKeyToAccount(process.env.EVM_PRIVATE_KEY)));
The wrapped fetch handles the 402 round-trip transparently: it reads Payment-Required, picks a network you registered, signs, retries with the payment header and returns the paid response. A complete, runnable version that creates and funds a throwaway Solana wallet is in examples/pay.mjs. Python and other clients: see the x402 SDKs at https://github.com/x402-foundation/x402.
The MCP server at https://tlacuilo-jet.vercel.app/mcp (Streamable HTTP, no authentication) exposes the same 35 paid tools plus two free ones, catalog and health. Tool names are the HTTP paths with underscores (web_read, sec_filings, banxico, uma); path parameters become arguments. Payment travels inside MCP _meta (x402/payment and x402/payment-response) exactly as specified by @x402/mcp; a client wrapped with @x402/mcp pays automatically, with an optional approval hook per call.

A tool call without payment returns an MCP tool result with isError: true and the PaymentRequired object in structuredContent; wrapped clients pay and retry. A runnable client that lists the tools, calls catalog and pays for one tool is in examples/mcp.mjs.
Prices are per call, in USD, settled in USDC. Every tool is documented with parameters and a runnable example in the free catalog at /api/v1.
