How this service works
Call when an agent needs card matches redacted in text. Nothing is stored. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/redact-card first.
Output
Returns the input text with any detected payment card numbers replaced by a redacted placeholder, leaving all other content intact. No data is stored server-side.
Example use cases
Sanitize customer support transcripts
“Before we store this support chat log, can you scrub out any card numbers the customer may have shared? Here's the transcript: 'Hi, my card 5500005555555559 was charged twice yesterday and I need a refund.'”
Clean user input before database write
“A user just submitted a form and I think they pasted their card number into the notes field by mistake — can you redact any card numbers from this text: 'Please process my order, my Visa is 4012888888881881 expiry 12/26.'”
Anonymize payment logs for audit
“I need to share this payment log with an external auditor but first please redact any card numbers that appear in it: 'txn_001: card 371449635398431, amount $50.00, approved.'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/redact-card?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, stateless, guaranteed-cost ($0.002 USDC) card-number redaction step with no data retention — ideal for pre-storage sanitization, PCI compliance pipelines, or scrubbing logs before sharing. Prefer the free sandbox endpoint (/v1/sandbox/redact-card) for testing. Choose this over an LLM-based approach when you need deterministic, regex/pattern-based redaction without risk of hallucination or data retention.
Side effects
- Text exceeds 100,000 character limit — request rejected with validation error
- Empty or missing text field — request rejected
- Malformed JSON body — returns 400 error
- Payment of $0.002 USDC not provided or rejected — returns 402 Payment Required
- Card patterns not recognized if heavily obfuscated or non-standard formatting
