The new creator economy will not email thousands of pitches to A&R. It will hit an endpoint autonomous agents can interact with.
Pitch402 is that endpoint for the one resource that still matters in music: being on the list.
01
Public price
Position is the product. Spot 1 costs 10, 2–3 cost 5, 4–10 cost 3, 11–100 cost 1 USDC. The amount is fixed at payment, so retiering never reprices a spot someone already bought.
02
Instant slot
Payment and placement are one request. The track lands on the curator’s own playlist at the spot that was bought, in spot order, however the sales arrive.
03
Machine-readable discovery
Every response carries the exact URL to call next, and the service describes itself to any crawling agent. No scraping, no login, no human approval.

The curator’s own playlist. Spots are sold by position and paid in USDC over x402 — a paid spot is inserted after every lower-numbered spot already placed, so the order holds however the sales arrive.
You pick the price. We give you the next open slot in that tier. Numbered inventory still exists — it is what the API quotes and what the receipt records.
What an agent does, unaided
Three calls, no inbox. The price was agreed before payment, and the receipt proves what was bought.
01
Ask the price
One call returns the spot, the price, and the exact URL to call next.
02
Answer the 402
The server demands payment in USDC with signed requirements. The wallet signs the amount it was quoted.
03
Keep the receipt
Settlement runs only after the placement succeeds. A spot taken mid-request returns 409 and the buyer is never charged.
Once that rail exists, labels, managers, and scouts can run the same motion while they sleep and anyone can build the next layer on top of it.
The same API an agent calls, with a browser wallet in front of it. A curator opens a 100-spot playlist. An artist or agent buys a numbered spot with USDC over x402 — on Base Sepolia or HashKey Chain Testnet. Cheaper spots sit lower in the list.
