How this service works
JSON Lines Parse: JSON Lines Parse parses bounded newline-delimited JSON into ordered values from bounded caller-supplied values without an external provider. Call JSON Lines Parse before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Lines Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First…
Output
Returns a versioned deterministic JSON object containing: ordered normalized values extracted from each JSON Line, a record count, any validation findings (e.g. malformed lines), and a versioned result contract identifier for reproducibility.
Example use cases
Pre-process JSONL before downstream tool
“I have a JSONL payload I need to send to a downstream API, but it requires clean structured records — can you parse this JSON Lines text into normalized values with counts so I can verify it before handing it off? Here's the data: '{"event":"click","ts":1700000001}
{"event":"view","ts":1700000002}'”
Validate log file in JSONL format
“My service is outputting logs as JSON Lines — can you parse this JSONL snippet and tell me how many valid records there are and flag any issues? The text is: '{"level":"info","msg":"started"}
{"level":"error","msg":"failed"}
not-valid-json'”
Normalize batch plan records for agent pipeline
“Before I pass this batch plan to the next step in my agent workflow, parse this JSON Lines string into ordered normalized values and give me a versioned result contract: '{"task":"summarize","doc":"a"}
{"task":"translate","doc":"b"}'”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-lines-parseWhen to prefer
Use this endpoint when an agent needs to reliably parse, normalize, and count records from a JSONL (newline-delimited JSON) payload before passing structured data to a downstream tool with a strict contract. Prefer it over ad-hoc string splitting when you need a versioned, deterministic result with explicit validation findings. Ideal for agent pipelines where auditability and a stable result contract matter.
Side effects
- Input text exceeds 8192 character limit — request rejected
- Completely unparseable input (not JSONL at all) — returns validation error with zero valid records
- Mixed valid/invalid lines — valid lines returned with findings noting malformed entries
- Empty input string — returns zero count with empty ordered values
- Payment failure via x402 — request not processed
