Built for automated pipelines
Send JSON over HTTPS. Paid calls use x402 with USDC on Base. No account or subscription. Maximum 20,000 rows and 200 columns per table; each CSV must be at most 500,000 characters. Results show up to 100 details per category, with full counts.
Invalid input is rejected before payment. Your CSV is processed in memory and is not written to application storage. CSV contents are not sent to the payment facilitator. Hosting infrastructure may retain request metadata. Formula warnings are heuristics, not a security certification.
