Schemas 10

The contract defines 10 schemas that model the data the API accepts and returns. The most detailed are PaymentAccounting (7 properties), Capabilities (5 properties), Error (2 properties). Each schema is shown below with its type and property counts.

Bytes32
string
A 32-byte hex value, lowercase. Transaction hashes and references.
ErrorCode
string
Every code this API can return. Stable identifiers - branch on these, never on the human-readable text or the HTTP status alone.
Address
string
An EVM address.
Capabilities
object
5 properties
AmountUnits
string
An integer count of micro-USDC (6 decimals), as a string. 2500000 is 2.50 USDC. Used wherever a decimal would invite a rounding error - notably refund amounts.
PaymentAccounting
object
Every unit of a settled payment, read from the chain rather than recomputed from what someone said they would charge.
7 properties

2 properties 1 required
MerchantAction
string
What to do about a result. - SUCCESS - done, nothing owed. - WAIT - the money may already have moved. The transaction exists and has not settled to the require…
Token
string
A signed P2Flux capability: payment intent (p2f1.), setup token (p2setup2.), subscription capability (p2s2.), cancel token (p2cancel1.) or refund token (p2refu…
Amount
string
A USDC amount as a decimal string, up to 6 decimal places. Never a JSON number: binary floating point cannot represent most decimal prices exactly, and this is…

Where this information came from

This is an independent, third-party profile of P2Flux API One-time payments API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
