Swift Bot Labs Toolbox – JSON Diff
x402
Swift Bot Labs Toolbox – JSON Diff is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).
Computes a JSON diff (RFC 6902-style patch operations) between two JSON values, returning the list of add/replace/remove operations and whether the values are equal.

How this service works
62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.
Output
Returns a JSON object with an 'ok' boolean, the tool name 'json-diff', and a 'result' object containing: 'count' (number of diff operations), 'equal' (boolean indicating whether the two inputs are identical), and 'operations' (array of JSON Patch-style objects each with 'op', 'path', and optionally 'value' and 'old' fields).
Example use cases
Audit API response changes
“I have two versions of an API response — the one from yesterday: {"status":"active","limit":100} and today's: {"status":"active","limit":200,"tier":"pro"} — can you diff them and tell me exactly what changed?”
Config file change detection
“Before deploying, can you compare my old config {"debug":false,"workers":2} with the new one {"debug":true,"workers":4,"region":"us-east"} and list every modification?”
CI pipeline JSON schema validation
“In my CI pipeline I want to check whether the generated output JSON {"build":"abc","passed":true} differs from the expected baseline {"build":"abc","passed":true} — are they identical or is anything different?”
Technical details
Endpoint
POSThttps://x402-toolbox.swiftbotlab.workers.dev/v1/json/diff?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, machine-readable diff of two JSON values — especially when you want RFC 6902-style patch operations (add/replace/remove with explicit paths) rather than a visual or textual diff. It is ideal for agents that need to programmatically process change sets, audit configuration drift, or validate that a transformation produced the expected output. Being pay-per-call with no account setup, it suits ephemeral agent workflows where spinning up a dedicated diff service is overkill.
Side effects
- Invalid JSON input in 'a' or 'b' fields returns an error response
- Missing required fields 'a' or 'b' causes a 400-level error
- Payment not provided or insufficient USDC causes an HTTP 402 response requiring x402 payment
- Very large JSON payloads may hit Cloudflare Workers size limits
- Malformed JSON strings passed as the 'a' or 'b' values (when string-encoded) may fail parsing
