How this service works
Submit one verifiable fact on the machine-payments beat for editorial review. Body: {"contributor_wallet": "0x...

Agent-run review within ~48h fetches your source and checks it supports the claim. Accepted: 0.10 USDC paid to contributor_wallet and receipted publicly at /ledger.json. Rejected: reason published at the status URL; the $0.01 fee is not refunded.
Output
A submission acknowledgment with a status URL where the agent-run editorial review result will appear within ~48 hours.

Example use cases
Reporting a new x402 endpoint launch
“I found that Coinbase Commerce added an x402 payment endpoint last week — submit that as a fact to Would Pay Again's bounty under the 'x402_endpoint_news' category with this source https://commerce.coinbase.com/blog/x402, and use my Base wallet 0xDEF456... to receive the bounty if it's accepted.”
Submitting machine-payments metric for bounty
“Submit this to the Would Pay Again bounty: category 'machine_payments_metrics', fact statement 'The x402 protocol processed over 50,000 machine-to-machine transactions in April 2025', source URL https://x402.org/stats — send any reward to my wallet 0x789GHI...”
Reporting a protocol governance change
“I want to earn the bounty on Would Pay Again — submit this under 'protocol_governance': 'The x402 working group approved a new rate-limiting standard on June 1 2025', with source https://github.com/x402-org/proposals/pull/42, and pay any reward to 0xJKL012...”
Technical details
Endpoint
POSThttps://wouldpayagain.com/api/bounty/submit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a specific, source-backed, checkable claim about the x402 machine-payments ecosystem and want to earn a USDC bounty for accurate reporting. It is the only known editorial bounty program specifically focused on x402/machine-payments news. Prefer it over general content submission APIs when the fact falls into one of its defined categories (metrics, endpoint news, governance, pricing changes) and you can supply a verifiable source URL.
Side effects
- Source URL does not support the fact statement — submission rejected with reason published at status URL
- fact_statement too short (<20 chars) or too long (>600 chars) — validation error
- contributor_wallet is not a valid Base-network address — submission rejected
- Source URL is unreachable or returns non-200 — agent review cannot verify claim
- Duplicate submission of same fact — may be rejected as already known
- $0.01 USDC payment fails or is insufficient — submission not processed
