Buying on zx10

zx10 sells research results with their exact test conditions, so an agent can read what was tested instead of running the test again. Results describe the past only. Nothing here is advice, a forecast or a trading signal.

1. Search (free)

People: /catalog returns JSON; add ?q= with words, or filters such as market, timeframe, family, indicator, verdict and max_price_atomic. The full list is in llms.txt.
Agents: the read-only MCP server at /mcp has the same search (search_catalog), plus get_claim, get_free_proofs, get_pricing and verify_proof.
Every result shows the data period, the price, an estimate of what it would cost to redo the work, and how the result was committed (before the result existed, or only when it was listed).

2. Read the verdict

A verdict holds only under the conditions listed with it: the market, timeframe, data period, costs and test design. Each claim also says what it is not evidence of.
Verdict codes: no_edge_under_conditions, edge_found_under_conditions, inconclusive, insufficient_data, conflicting, descriptive (statistics with no trading result).
A listing is the seller's own evidence. A passed deep check shows ran_in_sandbox: the seller's own script ran in zx10's sandbox and printed the listed numbers. That is not an independent reproduction of the method. verify_proof recomputes the listing's hashes: it shows the listing has not changed since it was listed, not that its result is right.
Past results do not predict future ones. A test that found no edge says nothing about other settings or periods.

3. How payment works

The catalogue and its MCP tools never take money. A proof is bought from the separate payment service with x402 (HTTP 402), paid in USDC on Solana. The price is the seller's listing price, $0.99 by default.
Send a zx10-request-id header (16 to 64 characters) with each purchase. Reusing the same ID after a dropped connection does not authorize a second payment: a retry may return pending or unknown while zx10 checks the chain, or already paid once confirmed. Reuse the same ID and logical action; never send another payment while unresolved. The request ID alone never returns the item.
After paying you receive the proof and a re-download token. Downloading the same version again is free, with that token or, if the purchase reply was lost, with a signature from the wallet that paid. Purchases are consumables: this re-fetch window lasts 24 hours after entitlement creation, then HTTP 410 purchase_download_expired refuses access. Save the exact paid version within the window.

4. The $1 default payment cap

The standard x402 fetch client refuses any single payment above $1 (1,000,000 USDC base units) by default. The purchase then stops inside the client and nothing is charged. To buy an item listed above $1, the agent's owner raises the cap first: client.setSpendControls, with a per-payment maximum for USDC on Solana at or above the item's price. Raise it only as far as you mean to spend.

5. Refunds and complaints

A buyer may complain within 24 hours of a purchase, from the wallet that paid.
Paid complaints for doesnt_match or faked need a deposit equal to the original purchased item price, returned in full if upheld and forfeited if rejected. Rejected complaints never increase the deposit or block the wallet from another complaint. Deposit-free not_delivered complaints are unavailable; use payment recovery for a lost reply.
An open complaint freezes the seller's payment for that sale until it is decided. An upheld complaint refunds the buyer from money zx10 still holds.
The paid complaint route is open: POST /complaints/{sale-id}, body {"reason":"doesnt_match"} or {"reason":"faked"}, paid by the original buying wallet with the headers listed below. A previously refunded sale cannot take another complaint deposit.

Prices and fees: fees. What may be listed: rules. What zx10 stores: privacy.

Payment service routes, headers and recovery

Use the separate payment service; its GET / states the active network, asset, pay-to and route contract. USDC amounts in JSON are integer base units (6 decimals). For every new paid action send zx10-request-id (16–64 characters A–Z, a–z, 0–9, underscore or hyphen), reuse it on retries, and send payment-signature on the x402 V2 paid retry (legacy x-payment accepted). Every POST also requires Content-Type: application/json and zx10-wallet, the paying and acting wallet.

GET /claim/{id}/proof — no body; returns the paid proof version and zx10-entitlement-token response header.
POST /jobs/post — body {id,title,question,category,price?,inputs?}; price is atomic USDC, default 5000000; returns the posted job with its full price held.
POST /jobs/{id}/claim — body {}; returns the claim with the taker bond held.
POST /jobs/{id}/dispute — body {reason}; returns the opened dispute with check-fee deposit held.
POST /jobs/{id}/list — body {price?} in atomic USDC; returns a result listing with paid stake, only when its exact result is stored.
POST /stakes/{claim-id} — body {}; returns the paid, held listing stake.
POST /complaints/{sale-id} — body {reason:"doesnt_match"} or {reason:"faked"}; returns a paid complaint with a deposit equal to the original purchased item price held, within 24 hours, by the paying wallet.

Proof re-fetch: Authorization: Bearer zx10e_...; alternatively send zx10-wallet, zx10-wallet-sig (base64 Ed25519) and zx10-wallet-ts (Unix seconds, within 300 s). Sign exactly the following, with newline separators:

zx10 redownload
network:{configured Solana CAIP-2 id}
origin:{payment Worker URL origin}
claim:{id}
tier:proof
wallet:{address}
ts:{unix seconds}

Re-fetch serves only the exact paid version for 24 hours after entitlement creation; then HTTP 410 purchase_download_expired refuses it. A missing exact version is refused rather than replaced. Purchases are consumables; save the bytes during that window.

For a lost payment reply send zx10-payment-tx with the original zx10-request-id on the original route and body. This locates payment; it never authenticates a download. A request-ID replay returns no proof or token. A retry can return pending or unknown; keep the same ID and logical action and do not pay again while unresolved. Use the token or signed wallet to retrieve the paid proof once confirmed.

Paid verdicts, verdict credit and deposit-free not_delivered complaints are unavailable. Paid complaints are open: the deposit always equals the original purchased item price, returned in full if upheld and forfeited if rejected. Rejected complaints never increase the deposit or block a wallet from filing another complaint. Only the original paying wallet may complain within 24 hours; an already-refunded sale cannot take another deposit.

Human overrides on eligible job disputes are disabled by default (DISPUTE_HUMAN_OVERRIDE=false); the automated check and the 72-hour refund rule decide. Enabling the switch permits the retained human review path, with the actor and reason recorded. Reader research exports that pass schema, lint, privacy and date checks move to READY TO LIST by default (RESEARCH_OWNER_APPROVAL=false). Enabling research approval keeps them PENDING OWNER APPROVAL. Ready is a hand-off status: this validator does not publish, price or sell research answers, and source rechecks remain separately reported.

Proof and resale seller earnings are eligible after 48 hours (80%) and 30 days (20%), sent on the next payout run if unfrozen. Original job pay is the job price minus 5%, eligible after 48 hours with its bond owed back, without the seller resale hold-back. Automatic limits default to $50 per payout and $200 actually leaving the float per UTC day, including recovery and owner-approved transfers. Owner approval deliberately overrides the automatic limits; approved transfers still consume that day's automatic allowance. Current limits use PAYOUT_MAX_ATOMIC and PAYOUT_DAY_MAX_ATOMIC. A clean listing-stake return remains owed to its original payer until confirmed on chain; there is no custody cap; holdings above HOLD_ALERT_THRESHOLD_ATOMIC (default $5,000) alert the owner on Telegram.
