Agent Payload Tools – Pipeline
x402
Agent Payload Tools – Pipeline is a paid API for AI agents from api.agent-payload-tools.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-29).
Applies an ordered sequence of deterministic encoding, hashing, and JSON transformation operations to an input value in a single API call.

How this service works
Transform payload data through 1 to 12 deterministic steps in one call, including Base64 encode/decode, hex encode/decode, URL encode/decode, JSON parse/canonicalize, and SHA256/SHA512 hashing. Useful for multi-step data transformation, payload processing, encoding pipelines, decoding pipelines, and chained transformations.
Output
Returns the final transformed value after all ordered operations have been applied in sequence. The result type depends on the final operation — it may be a string (encoded/decoded), a hex digest, a base64 string, a parsed JSON object, or a canonical JSON string.
Example use cases
Sign-ready canonical JSON preparation
“I need to prepare this JSON object for signing — first canonicalize it, then SHA256 hash it, then base64 encode the result: {"amount":100,"currency":"USD","recipient":"alice"}.”
Decode and parse a base64 JWT payload
“I have this base64-encoded JWT payload segment and I need to first base64 decode it, then parse it as JSON so I can read the claims: 'eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIn0'.”
Hex-encode a hashed API secret
“Take my API secret string 'my-super-secret-key-2024', SHA512 hash it, then hex encode the output so I can store it safely.”
Technical details
Endpoint
POSThttps://api.agent-payload-tools.workers.dev/pipeline?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, server-side encoding, hashing, or JSON transformation without running code locally — especially when chaining multiple operations (e.g. canonicalize → SHA256 → base64) in a single call. It is ideal for AI agents that cannot execute arbitrary code but need cryptographic or encoding primitives. Prefer it over general-purpose code execution tools when only encoding/hashing/JSON operations are needed, as it is cheaper and auditable.
Side effects
- Invalid operation type specified — returns error if enum value is not one of the ten supported operations
- Input incompatible with operation — e.g. base64_decode on a non-base64 string returns a decoding error
- Chained operation type mismatch — e.g. trying to json_parse a value that is not a valid JSON string
- Exceeding maxItems of 12 operations returns a validation error
- Malformed input JSON in the request body returns 400
- Payment not included or invalid x402 payment header returns 402 status
