What it does
The specific capability behind this listing, and where to get it.
Repair malformed JSON from LLM tool calls and agent-to-agent handoffs — fixes trailing commas, single quotes, truncation, markdown code fences, comments, and python literals, and can validate/coerce the result against a JSON Schema. Free deterministic tier; pay-per-call LLM fallback via x402 (USDC on Base). Tools: repair_json, validate_json.

Is Jsonaut good value?
How its price compares with genuinely comparable providers.
Priced near the market for its buyer tier.
Basis: same-tier-tier plans in the niche, any billing unit (4 providers), USD monthly, pricing observed 2026-10-27. The per call plan ($0.01/mo) sits 0% above that median of $0.01. Thin evidence: fewer than five comparable providers, so treat the position as indicative. Other cohorts on this page (niche-wide tier peers, nearest products by capability) are labelled where they appear.
Compared with Data Extraction Pipeline
Positioned against the observed p25 / median / p75 of comparable providers at the same buyer tier and billing unit (the basis is stated with each verdict above). See the plans above for the percentile and its cohort size, and the full niche market for peers.
