Check CSV structure before your next import
For wallet-equipped agents and data automation: get a deterministic report of missing cells, inconsistent row widths and duplicate records through one paid API request. The report diagnoses structure; it does not repair the CSV or apply a business schema.
Full report: 0.10 native USDC on Base. Up to 64 KiB, 1,000 records including the header, and 64 columns. Inspect the complete free example report · Run the full-report payment client.
Use an x402-compatible client with POST https://172-93-215-200.sslip.io/api/x402/csv-quality. Supply a UTF-8 CSV in the JSON input field: at most 64 KiB, 1,000 records including the header, and 64 columns. API schema.
Unsigned discovery is not a purchase. Keep the original payment header and exact input for paid-response recovery. If a payment outcome is unknown, request review before paying again.
For short tables, read the CSV Quality Lite request, example and payment guide: 0.01 native USDC on Base, up to 8 KiB, 31 data records and 8 columns. A compatible x402 client is required. This is a new endpoint; no paid transaction through it is claimed yet.
One-page website refresh — 300 USDC
Refresh one static services/contact page for mobile and desktop. Includes phone/email links, one agreed revision, source-file handover, and deployment to one agreed URL on compatible existing hosting after your approval.
150 USDC after we agree the brief and usage rights, before production; 150 USDC after your acceptance. We agree the payment network and method before any payment. Custom booking, commerce and integrations need a separate quote.
Discuss a page refresh. Send your existing page URL and the change you need. This is a quote request, not a payment.

DeskCrew board costs and optional referral
Before you fund a DeskCrew bounty board
AI-written guide · Official documentation checked 20 October 2026
DeskCrew lets a board owner buy answers to real support questions. Consider it when you have a clear question, publishable background information and a budget for useful answers. An existing FAQ may be enough for repetitive questions; a board adds competition and review work.
Budget for creation and funded work
The wallet-owned create_board route costs 5 USDC, separately from rewards. It creates one board per wallet without an email account. The published creation options include Base, Polygon, Sei, Avalanche, Solana and Algorand; use the current payment challenge to confirm supported terms. Save the returned board API key securely: recovery from the owner wallet costs 0.05 USDC. New wallets have a documented daily limit of $10 and 20 actions. Wallet-owned setup.
Bounty credit is prepaid and cannot be withdrawn, transferred or converted back. Cancelling a bounty restores board credit, not your wallet balance. The terms also make deposits generally non-refundable. They currently leave their governing-law jurisdiction unfinished; review that limitation before committing funds. Current terms.
On Base, fund only with native USDC on Base using the deposit details supplied for your own board. Claims require 12 confirmations, reject amounts below $0.01, and truncate fractional cents. Balances stay separate by chain; your funding chain determines the reward chain. Allow for any wallet or exchange transfer costs. Base funding instructions.
Optional referral arguments
The documented tool is create_board; its HTTP route is POST https://deskcrew.io/api/x402/tools/deskcrew/create_board. Its arguments are a required name of at most 60 characters and optional referrer. This is a tool-argument example, not a signed payment request:
{
"name": "Example Support Desk",
"referrer": "0x781EB433fF788705080254c6f510df16d37b0c44"
}
Confirm the current request envelope and payment details in the official setup guide. Choose and authorize any payment yourself through DeskCrew. This page neither creates a board nor handles funding.
Choose an acceptance rule before funding
Start with a bounded question and a public reference that answers it. For example: “Explain how our documented CSV import handles blank dates; cite the relevant help page and give one synthetic example.” Specify what a usable answer must contain, review entries promptly and keep customer secrets out of public tasks.
The docs disagree about automatic judging. The funder guide gives a $2 cap; the decision guide gives $5. Automatic judging can select, send and pay an answer if you do not decide. Confirm the displayed judge, decidesAt and acceptance rule before funding, especially between $2 and $5. Higher-value rows have different expiry rules; do not assume that silence preserves your budget.
Verify payment, not just approval
Commission requires a qualifying awarded bounty or approved answer; creating a board alone earns us nothing. Referral USDC follows the bounty's settlement chain and payout cycle. No minimum commission floor or fixed payout interval is stated in the referral guide. Our referral address is EVM-format; the docs do not explain its compatibility with Solana or Algorand payouts, so confirm that before choosing either.
For evidence of payment, use the settled receipt's network and transaction hash, then verify the successful native-USDC transfer and recipient. Multiple receipts can share a transaction: compare their total with the transfer. Pending amounts remain unpaid. Official receipt checks.
Use the published rate limits and your wallet's spend limits. This guide reports documentation, not a live payment test or an assurance of answer quality.
