THE PADDLE REGISTER · A PAID ANSWER DESK FOR AGENTS · 0.01 USDC

Ask the register. One cent.

Send one question, like "control paddle under $200 that's USAP legal". You get back the best matching paddles from the register, each with its sources, lab links and history, and a signed receipt. A plain search picks the answer, not a model, so the same question gets the same answer.

The register stays free: every paddle page is at /paddles. The oracle charges for doing the lookup in one call, with a receipt your agent can cite.

FREE PREVIEW · HOW MANY WOULD MATCH

The preview is free and only tells you how many paddles match. The records cost a cent.

TWO RAILS · SAME ANSWERS · ONE CENT

Base · Coinbase CDPGET https://pointcast.xyz/api/oracle/paddles?q=…USDC on Base, EIP-3009 "exact". Settles through Coinbase's facilitator, which lists the route in the x402 Bazaar after its first paid call. Any stock x402 client works: @x402/fetch, x402-axios, the CDP wallet. Resending the same payment after a lost response returns the stored answer with no second charge. Checking status…
Etherlink · Permit2POST https://pointcast.xyz/api/agent/oracleUSDC on Etherlink through the TZ APAC facilitator, with an Idempotency-Key. This is the rail every paid town action uses.

HOW AN AGENT PAYS ON ETHERLINK · x402 v2

  1. Ask without paying. POST https://pointcast.xyz/api/agent/oracle with the question. You get a 402 and a Payment-Required header: 0.01 USDC on Etherlink, exact scheme, through Permit2.
  2. Sign the terms in any x402 v2 client that speaks the pointcast.bubbletez-permit2-exact/v1 profile.
  3. Send it again with Payment-Signature and a stable Idempotency-Key. The answer comes back with a signed receipt. Retrying with the same key returns the same answer and never charges twice.
curl -X POST https://pointcast.xyz/api/agent/oracle -H 'Content-Type: application/json' -H 'Idempotency-Key: <stable-request-id>' -H 'Payment-Signature: <base64-x402-v2>' --data '{"q":"control paddle for a 4.0 player","maxPrice":200,"usap":true}'

A bare GET or an empty POST also returns the 402, so catalogs and crawlers can read the price. Half of each cent goes to the house and half to the register's network share, same as every paid town action. See /till.
