How this service works
200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
Returns a JSON object containing: 'records' (array of parsed JSON objects), 'count' (number of records returned), 'truncated' (boolean indicating if the limit cut off additional records), 'lines_blank' (number of blank lines in the input), and 'lines_total' (total number of lines including blank).
Example use cases
Ingest JSONL export from database
“I have a JSONL dump from our database — can you parse this text and give me the first 100 records as structured JSON objects? Here's the data: '{"user_id":1,"email":"alice@example.com"}\n{"user_id":2,"email":"bob@example.com"}'”
Count records in JSONL log file
“How many records are in this JSONL log snippet? I also want to know if there are any blank lines: '{"event":"click","ts":1700000001}\n\n{"event":"view","ts":1700000002}'”
Sample first records from large JSONL stream
“Take this large JSONL payload and just give me the first 10 records so I can preview the schema: '{"product_id":"A1","price":9.99}\n{"product_id":"A2","price":14.99}\n...'”
Technical details
Endpoint
GEThttps://fastx402.tools/jsonl-parse?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, stateless, pay-per-use JSONL parser with no API key setup — ideal for AI agents handling ad-hoc JSONL data from exports, logs, or data pipelines. Prefer it over custom parsing logic when you want a hosted, reliable micro-service that handles blank lines, counting, and optional truncation out of the box.
Side effects
- Malformed JSON on any line causes a parse error for that record or the entire request
- Input data exceeding size limits may be rejected
- Limit parameter outside 1–1000 range may return an error
- Non-JSONL input (e.g. plain JSON array) may not parse correctly
- Network or payment failure returns 402 or 4xx error
