A server that changes its tool descriptions after being approved ("rug pull") can slip new instructions to agents. Re-check what changed before trusting it.

5base_rate
How often it happens anyway. How many coins first traded inside a market-cap band in a window, how many of those then reached 2x, 5x, 10x and 20x within 3 h, and the median peak. A crossing is a coin's first trade with a market cap inside the band (a coin that jumps over the band in one trade has none); the peak is the highest market cap, curve or pool, in the 3 h after it; USD is at the SOL price of the trade's hour. $0.005 a call, USDC on Solana over x402.
wallet_records
What these wallets have been since March 2025: for each address its class by rule (winner: took out more than it put in over 20+ coin-weeks; bot: a coin traded 20+ times in a week or 500+ coins; supply_seller: took out 1.5x what it put in, 100 SOL or more; new: no record before the mint you name, or before today) and the numbers behind it: pnl_sol, put_in, took_out, coins, first_seen. Up to 50 addresses a call. $0.01 a call, USDC on Solana over x402.
launch_record
This launch, historically. The deployer's record at this launch (launches before it, graduations, the gap to the previous one, launches in the last day), the bundle at creation (buyers in the first 10 s and the share of supply they took), the insiders' share now, curve progress, and how launches that looked the same at this age went over their next 24 h (graduation share, peak and close quantiles, how many died). $0.005 a call, USDC on Solana over x402.
replay
Your picks, replayed honestly. Picks with timestamps and sizes in; what they made, pick by pick and in sum, every coin in the window counted including the dead ones, filled at the pool as it stood after your latency, with every fee, the fixed costs and the bankroll you set. The most recent eight weeks come back apart from the rest, once per rule to each payer. A run is a queued job: the result is {id, state: queued}; poll replay_result with the id. $2 a run, USDC on Solana over x402; a run that fails is rerun free on the same id.
replay_result
A replay's result: the job's state, and the replay once done with the execution model it charged. Free; the id is the receipt.
pumpdata examples
Calling pumpdata.fun from an agent or a script: every PumpSwap trade, ever, and every pump.fun bonding-curve trade since March 2025, 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.
| call | asks | price |

GET /baserate?band=15k-28k&from=<iso>&to=<iso>&venue=any | how many coins first traded inside a market-cap band in a window, and how many reached 2x, 5x, 10x, 20x within 3 h | $0.005 |
POST /wallets {"addresses": [...], "mint": "<optional>"} | what up to 50 wallets have been: winner, bot, supply seller, new, with the SOL behind it | $0.01 |
GET /launch/{mint} | the deployer's record, the bundle at creation, the insiders' share, and how launches that looked the same went over 24 h | $0.005 |
POST /replay {"picks": [{"mint", "at", "size_sol"}, ...]} | up to 500 picks replayed against the chain's history with fees and fills (a queued job; poll GET /replay/{id}) | $2 |
Free, no payment: yesterday's base rate for every band at /public/baserate.json, refreshed hourly.

How a call is paid
- Call without payment. The answer is 402 with the offer in the body and in the
PAYMENT-REQUIREDheader: price, payee, network (USDC on Solana mainnet), and a Bazaar declaration of the inputs. - Sign a USDC transfer for that amount with your wallet (the facilitator pays the network fee; you need no SOL).
- Call again with the signed payment in
PAYMENT-SIGNATURE. The answer is the data, with the receipt inPAYMENT-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/fetchand a Solana keypair.python.py: the 402 and the free file from Python; the paid retry with thex402package.mcp.md: the same calls as MCP tools (Claude Code, Cursor, Cline, Claude Desktop).
