pumpdata examples

Calling pumpdata.fun from an agent or a script: every pump.fun trade, ever, bonding curve and PumpSwap, since pump.fun's first day, read from the chain's ledger with the dead coins kept, sold by the call in USDC over x402 on Solana. No key, no account.

How a call is paid

  1. Call without payment. The answer is 402 with the offer in the body and in the PAYMENT-REQUIRED header: price, payee, network (USDC on Solana mainnet), and a Bazaar declaration of the inputs.
  2. Sign a USDC transfer for that amount with your wallet (the facilitator pays the network fee; you need no SOL).
  3. Call again with the signed payment in PAYMENT-SIGNATURE. The answer is the data, with the receipt in PAYMENT-RESPONSE.

The x402 client libraries do steps 2 and 3 for you. Every answer carries X-Data-As-Of (the build it comes from) and X-Data-From (where the data begins). A window with no data answers 404 and costs nothing.

The examples

  • curl.sh: the 402 and the free file, no wallet needed.
  • node.mjs: a paid call with @x402/fetch and a Solana keypair.
  • python.py: the 402 and the free file from Python; the paid retry with the x402 package.
  • mcp.md: the same calls as MCP tools (Claude Code, Cursor, Cline, Claude Desktop).

Check the base rate before you ape: agent recipes

A paid GET /baserate ($0.005) in four shapes, each 17-21 lines. The payer key comes from PUMPDATA_PAYER_KEY (base58, or the solana-keygen JSON array). The wallet needs USDC and no SOL. Never commit the key.

The three framework files reuse baseRate() from x402-fetch.ts. Run on their own, they call the action or tool directly, the way the framework would, so no model or agent is needed to try them.
