Automated competitor intelligence pipeline
“Set up API access to MRR Ledger for our market research workflow — purchase the hobby plan with USDC so we have 2000 requests per day to track agentic business MRR trends.”

Technical details
Endpoint
POSThttps://mrrledger.com/api/v1/passes?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs programmatic access to MRR Ledger's database of revenue-generating agentic businesses and must first obtain an API key via a crypto micropayment. This is the required first step before any MRR Ledger data queries can be made. Prefer this over manual sign-up flows when operating autonomously with a USDC wallet.
Side effects
- Insufficient USDC balance — payment fails and no key is issued
- Invalid or unsupported plan tier — returns error or no response
- Network or x402 payment protocol failure — transaction not confirmed, no key returned
- Duplicate purchase within active period — key may not be re-issued or may return existing key
- Expiry already passed on a previously issued key — agent must repurchase
